Changes
|
11.06.04
|
| • | The snap indicator on the status bar now includes the snap value. |
| • | Using a mouse click to change the 3D cursor position did not update the indicators on the status line. |
| • | Using a mouse click to change the 3D cursor position did not work when there was no drawing loaded. |
| • | The Browse button on the Open Drawing dialog did not always set the drawing type correctly (i.e. choosing print templates when you were opening a drawing). |
| • | The ribbon import command did not properly create legacy menus. |
| • | Undoing some activities did not refresh the dockable tree. |
| • | The SilverC-API-only relocate front/back commands did not update the dockable tree. |
|
11.06.03
|
| • | There have been speed and behavior upgrades to the dockable tree. |
| • | A crashing bug was fixed in the macro editor. |
| • | The macro editor no longer marks all loaded macro files as modified |
| • | Some interactive tasks, like copying objects, are now faster, especially when working in large drawings. |
| • | A SilverPlus development platform bug affecting menu switching while picking has been fixed. |
|
11.06.02
|
| • | Added post-command processing in the form of CV_COURTESY_PAINT_MSECS to help SilverC/SilverPlus developers address too-long busy-states which have no message pump, but which do execute a steady stream of engine commands. |
| • | Surface and force command excution was sped up. |
| • | We now locate the 3D cursor at the pointer location after Click+Drag to truck (when at rest). This is to restore legacy behavior. |
| • | The environment file now contains an option to have the mouse wheel recenter the view at the mouse pointer before zooming in/out. By default this feature is disabled to accommodate legacy settings. |
| • | The structure explorer has been revived as an option for the ribbon editor. This provides a dialog with a tree view and a list view, which makes relocating/grouping geometry within a particular block more convenient. |
| • | When copying a block to itself, that is when the source equals the destination, then the result will now be a sibling of the source block, rather than a child. This is to restore legacy behavior. |
| • | Added "New Symbol" and "New Textline" to the Structure > New ribbon. |
| • | The handling for menus with sub-items has been improved when non-leaf nodes were clicked. |
| • | The Quick Access Toolbar (ribbon tabs) may now be configured with the toolbar editor. This is manipulated via the toolbar called "standard". It may also be hidden/shown. This bar will be saved in ribbon definition files. Initially, SilverScreen will create a default. |
| • | You may no longer create a blank ribbon panel with the ribbon editor. |
| • | Ribbon editor now allows you to reorder the ribbons, enable/disable standard ribbons. |
| • | ESCAPE/Cancel of ribbon/toolbar editing dialogs has been fixed. |
| • | Changing the tooltip for a user-defined command now updates the ribbon immediately. |
| • | View > Layout > Window Close and View > Zoom > Geometry have returned to the standard View ribbon, and Zoom > Geometry now works properly with the group commands. |
| • | Selecting a block now begins by clearing away the event queue to prevent immediately scrolling away from the current block due to queued up keys which operated the menu. |
| • | The interactive preview you get when moving geometry has been expanded to include much larger objects/blocks/text. |
| • | The dialog which appears when you press the Browse button while opening a drawing now has a preview window. |
| • | The union q-group command restored the legacy destination block when the group contained different source blocks for the first and last item. |
| • | Selecting a vertex has been optimized for large drawings. |
| • | The dockable-tree performs many updates after a command is finished, rather than immediately. This improves interactive performance, especially when modifying the hierarchy. |
|
11.05.06
|
| • | A problem with group fencing was resolved. |
| • | There was a problem with icon_persist that manifested itself as blank (white) icon buttons. |
|
11.05.05
|
| • | The Edit > Polyline > Unlink command now allows you to select polylines in addition to polygons. |
| • | SilverScreen's static memory footprint was reduced slightly. |
|
11.05.04
|
| • | Shadow handling of solid objects which contained transparent nodes was improved. |
| • | The Render > Clip View command had its' mouse-wheel behavior fixed. |
| • | A rare-case crash in DWG import was fixed. This case was triggered by the presence of specialty-formatting characters (i.e. %s) within text-based fields, which also contained data errors. |
| • | When c-space alignment is set to automatic and the user splits the screen (i.e. 4-way, 6-way, 9-way) then the c-space is appropriately-aligned for the current window on the newly created screen. |
| • | SilverScreen variables had their performance boosted, particularly in heavy-use cases. |
|
11.05.03
|
| • | The system which cross-references the annotation system with the hierarchical geometry database after geometry-modifying activities (i.e. relocate, rename, delete, scale, rotate) has been optimized. This can lead to dramatic increases in performance when modifying geometry in a heavily annotated drawing. |
| • | The rendering of view-parallel lines that resolved to a single pixel on the screen was changed to provide results positionally consistent with the other rendering activities. |
|
11.05.02
|
| • | Minor update to repair SilverEngine platform linkage problem in Release edition of engine10.DLL. |
|
11.05.01
|
| • | Minor update to repair out-of-synch problem with engine.txt. |
|
11.05.00
|
| • | Image handling for very large images has been improved, particularly load speed for image types supported by a Windows Codec. |
| • | The texture manager will now properly save 24-bit texture images to disk. |
|
11.04.11
|
| • | When a triangulation results in unavoidable slivers, the algorithm now retries with rotated points, which often produces more satisfactory results. |
| • | The coalesce command now uses better testing to decide when two polygons are coplanar. It was brought into logical consistency with the 2D/3D Boolean operations. |
|
11.04.10
|
| • | The triangulation of polygons with very small holes was improved. |
|
11.04.09
|
| • | Color map table extensions were not used consistently. In prompting we displayed extension .CMT, but when saving the extension .MAP was used as the default. This meant newly created color mapping tables were not seen via the user interface. The save code has been changed to use the proper .CMT extension. Color mapping files with extension .MAP can be renamed to .CMT files to make them visible to the u/i. |
| • | The view > explore command now uses OpenGL rendering with displaylists for all the different rendering options. |
| • | There is a rudimentary Alias/WaveFront Object File import command. This will allow people to gauge interest in the format and import supported geometry, but does not import all of the material properties. |
| • | The xcopy internal prompting in its non-absolute forms improperly formatted the source drawing name, which generated error #25. |
| • | DWG/DXF Exports improperly set some vertex IDs in polygon-mesh primitives when a non-solid object contained a mixture of lines and complex polygons. |
|
11.04.08
|
| • | Sometimes the switch between filled and unfilled items was mishandled while printing, resulting in geometry being filled when it should not have been. |
| • | The page setup dialog did not properly restore the previously-used color mapping table. |
|
11.04.07
|
| • | The dialog used to insert text erroneously displayed a "Field cannot be left blank" message if the edit box used for horizontal text was empty. |
| • | Bos-level picking improperly filtered away choices when: A) Multiple items were "closest" and B) The choices were not decreased by the cursor-in-bos test. |
| • | The insert symbol command overran a character buffer when the model name exceeded 20 characters. |
| • | Secondary units/notation were not properly loaded from an annotation environment file, which caused new details to display the wrong units/notation when enabled (unless they happened to be the default secondary-units type). |
| • | We no longer translate a symbol definition by the model base point for AcDbBlockReferences. This was causing symbols to appear in the wrong locations when importing some DWG/DXF files. |
| • | Wireframe rendering via OpenGL did not always render details with the proper color. |
| • | Text lines now wireframe-render using a box when the screen height is 3 or fewer pixels. This can speed the presentation of text-heavy drawings which are fully zoomed out, and which therefore display mostly-illegible text. |
|
11.04.06
|
| • | If enabled via the environment file, then the solid modeler will colorize primitives referenced in error messages. That makes it easier to locate, for instance, an edge not shared by an even number of faces. The undo system will remove any colorization. |
| • | More changes made to light sources (including ambient) will generate automatic screen refreshes when light-based rendering (such as OpenGL). |
| • | The view explorer handles the transition between normal operation and exploring more smoothly. |
| • | The coalesce command handles holes in a manner that better accommodates triangulation algorithms. |
| • | Background images now automatically flip when their images are bottom-left-aligned so they are displayed right side up. |
| • | Both textured backgrounds and background images are now saved/restored with Screen Definition Files. Developers wishing to load textured backgrounds or background images will want to append the "background" keyword to their existing "screen open" commands. |
| • | The "convert drawing" command did not properly handle file path information for the model library. |
| • | The "library create model" command did not properly handle file path information for the model library. |
| • | When a model was replaced for a symbol it didn't always repaint unless the drawing were saved/reloaded. |
| • | When the last-write-time of an external model library changes and one of the models it contains is in-use, then the model will be automatically reloaded. |
| • | The depth-precision of OpenGL scenes was improved by considering just the visible geometry. |
| • | Linestyle with dots were not showing up on lines that had a width setting of 1. |
| • | The secondary units and notation were not initializing correctly for the detail properties dialog. |
| • | A placeholder did not appear around text-lines during interactive commands like move. |
| • | Several of the annotate commands did not properly appear on user-defined ribbons. Any ribbons defined with these commands should auto-correct with the new code (an erroneous button will disappear). |
| • | The paint_entity() SilverC API routine will now work in conjunction with DETAIL_NODEs. This change allows developers to make a particular detail easily stand out. |
|
11.04.05
|
| • | SilverScreen will now automatically triangulate line-based polygons that reference a vertex that is being moved, scaled, or rotated in a manner that would create a non-planar polygon. This step can preserve the meaningful boundary representation of the modified object and allow it to validate. Note: This applies to move/scale/rotate vertex, edge, or face only. |
| • | The text replace command did not work properly for centered text lines. |
|
11.04.04
|
| • | Commands that generate groups on-the-fly via the use of wildcard characters are processed as a single command if the number of items in the group resolves to one. This is to allow interactive commands that are specified via the pound character '#' to execute correctly. |
| • | Although binary STL files should never begin with "solid ", many were encountered in practice. If a file starts with "solid " we now additionally check for a few common STL keywords to help disambiguate this erroneous condition. |
| • | Setting the height while drawing a chord did not always work correctly. |
| • | Exporting a Stereo Lithography (STL) file did not properly handle file names that contained spaces in the file name or path. |
|
11.04.03
|
| • | The previous version contained an incorrectly-linked SilverEngine DLL. The file engine10.DLL was incorrectly linked with btree10D.DLL, which is appropriate only for the Debug platform. |
|
11.04.02
|
| • | The 3D cursor will now display a tooltip with the position, or else appropriate drawing information, if enabled via the environment file. This setting is disabled by default. |
| • | The camera develop command did not display frames when executing a program. |
| • | The camera develop command now has the ability to develop to the screen, rather than to disk. |
| • | The dockable tree didn't always update when it should have, particularly when hidden. |
| • | Changing the phong shading attributes now invalidates any display list so the rendering is regenerated to accommodate the change. |
| • | The render > record/develop commands now prompt the user to first save any unnamed drawing. This is because the corresponding frame file will reference the drawing by name, and therefore requires one to function properly. |
|
11.04.01
|
| • | Version 11.04 introduced a memory error to the DXF/DWG import and export code. This error can cause SilverScreen to crash or become unstable. |
|
11.04.00
|
| • | The save-as command has been expanded to offer the choice of different formats. |
| • | The save command now restores the activation status of the C-space. |
| • | The save command now restores the W-space cursor position, provided it was on the screen when the drawing was saved. |
| • | The select command was placed on the standard structure ribbon, in order to have a visual way to select the current block and/or object. |
| • | A startup problem in fullscreen mode has been fixed. When starting in fullscreen mode interactive operations left lines behind on the screen. |
| • | Version 11.03.02 introduced a courtesy save dialog that impacted an exiting application. |
|
11.03.04
|
| • | Improved F1 handling when inchar is active. |
| • | RETURN wasn't selecting the first point of Geometry > Measure > Distance after Undoing the first selection |
| • | The code which parsed text for the bubble u/i had an error in it, sometimes causing whitespace substitution. |
| • | Point sizes for text and details are now consistently handled. |
| • | Replacing a text-line's font via the properties dialog with a SilverScreen standard one (i.e. roman1) no longer erroneously generates error #97 - "Font library [] not found". |
| • | Moving a vertex that belonged to a phantom no longer generates a memory error. |
| • | Restructured paint code to use multimedia timer, which improved Direct2D throughput substantially. |
| • | You are now prompted to save macros after editing them, and also when exiting SilverScreen (if you haven't done so previously). |
| • | C_J and C_CRETURN are the same keycode, so the macro system now handles either as Ctrl-J. |
| • | The screen tabs toolbar has been revived, and is controlled via the Tools > Interface ribbon item. |
| • | The dockable tree now has an auto-hide mode, which can be selected via the Tools > Interface ribbon item. |
| • | Added -wipeui command-line option to remove toolbar, ribbon, gallery, and MFC-related data from the registry. This will remove all user interface customizations and window placements. It is intended to recover from catastrophic startup problems caused by erroneous interface definitions. The user will be prompted before the interface is wiped. |
| • | SilverEngine now establishes a default error-message handler in engine_initialize. This will allow error messages displayed by engine_initialize itself to appear. The API routine set_show_error_handler will override this behavior. |
| • | There are now user-definable toolbars which can be configured via the Tools > Interface ribbon item. Toolbar defintions are saved/restored via the import/export custom ribbon file commands. |
| • | The screen close command now prompts to save modified drawings. |
| • | The SilverC API screen-text routines (i.e. wstring, wstringc, etc.) were redone to fix display problems. |
| • | Improved CControlBar handling for SilverPlus applications |
| • | The SilverC API paint routines which accept COLOR_INVERSE now modify the paint color to be a non-background color if COLOR_INVERSE is set. This is to reclaim legacy behavior |
| • | Export and Import DWG/DXF now export and import the AutoCAD variables LTSCALE, LUNITS, LUPREC, ORTHOMODE, and INSUNITS. This change was made to allow units of measure and notation to be preserved |
| • | There was a problem zooming a drawing which contained sprites. Results were unpredictable. |
| • | The mouse wheel forewards/backwards events have been standardized to zoom in and out. This means they can no longer be tied to a macro, but they will be available when jumping, picking, drawing, and in a ready state. |
| • | A problem in the code that flashes a bos, such as when making a selection in the dockable tree, has been corrected. |
| • | Improved appearance of some polylines containing arcs which are imported via DXF or DWG. |
|
11.01.01
|
| • | There was a memory error in the code which highlighted a p-group, which lead to unpredictable behavior and sometimes related in crashing. An example operation affected was the move p-group command. |
| • | Changes to the standard directories via the file > paths command are now reflected in the open dialogs. So, if you change the drawing directory and then open a drawing you will be presented with the new location as the default (provided there are drawings present in that location). |
|
11.01.00
|
| • | This version was released to correct a mistake in extents computations introduced in version 11.0.09, which could lead to very bad zooming. |
|
11.0.09
|
| • | Solid modeler received performance update which will be most notable on large objects |
| • | Render clip-view command prompting was improved for rear-facing views. Now the default clipping plane faces forwards (with respect to the view) and positive increments move the plane forward (with respect to the view). This feels more natural and consistent than the previous technique. |
| • | The code which generates model names and matches symbols to them has been improved. Model names could sometimes get mixed up during a DWG or DXF import, resulting in self-referential models. |
| • | The view tab of environment files now have an option to auto-algin the c-space to a view. This mechanism is triggered when switching windows and/or screens and can ease drawing in multi-window settings. You simply click the view in which you wish to draw and the construction space automatically aligns accordingly. The default setting for this new feature is "never" to be backwards-compatible with existing environments. |
| • | Machines with multiple active network cards may have had startup problems due to a memory leak. |
| • | The view > visibility > enable command had prompting errors when rendering was enabled for non-opengl renderings (such as hidden-line). |
| • | Extents computations have been sped up which can modestly affect the performance of operations such as zoom. |
|
11.0.08
|
| • | Ribbon editor fixes had an initialization problem which impacted icon sizes. |
|
11.0.07
|
| • | The XYZ coordinate entry dialog was rewritten to fix errors with move and draw commands when working with a rotated c-space. |
| • | The Geometry > Coalesce command had a performance update. The effects are most notable with large objects. |
| • | The DWG import command removed underscore as a default hierarchy separator. The command syntax was expanded to allow [separator "list-of-separator characters"] to be appended and enforce earlier behavior. This change was made because bos-level entities which contained an underscore in their name yielded unintended organizational layers. |
| • | DWG Import performance was improved for files with a high number of layers. |
| • | The ribbon editor sometimes crashed when making changes to a user-defined ribbon. |
|
11.0.06
|
| • | Improved response of context-sensitive help system (F1 help) to Ribbon Interface |
| • | Fixed display problems in draw polygon equilateral and draw circle tangent commands |
| • | Improved responsiveness of swing and truck during interactive prompting |
| • | Fixed a paint problem with isolate reset |
| • | SilverC programs may once-again include files with a .C extension. |
| • | Fixed a problem with SilverC API message areas |
| • | Temporary screen saves/restores were made more efficient |
| • | OpenGL wireframe rendering now handles reference drawings |
| • | Offscreen entities were not properly added to OpenGL displaylists. |
| • | Import DWG now generates warnings when 3D points and vectors exceed the boundaries of a single-precision floating point numeral. This isn't necessarily an error, but often does indicate an uninitialized or poorly set elevation. |
|
11.0.04
|
| • | Introduction of OpenGL-based wireframe rendering |
| • | Introduction of Geometry > Reduce Vertices command to simplify geometry while maintaining the shape. This can be particularly useful importing point clouds or .STL files. |
| • | Fixed problems with interactive drawing experienced on some systems. |
| • | Fixed a memory error redrawing the properties of a p-group. |
| • | Environment paths will now be created, if possible, when starting up. This helps configure a new user on a multi-user system. |
| • | Added [SkyDrive] and [SkyDriveDocuments] to path variables for environment files, for example, the drawing directory may be specified as [SkyDrive]/drw. |
| • | Improved error reporting of invalid edge and vertex numbers in load drawing. |
|
11.0.02
|
| • | Introduction of a modern ribbon interface, with dockable hierarchial tree explorer. See Screen Appearance for more information |
| • | Introduction of anti-aliased lines using Microsoft Direct2D,which is "a hardware-accelerated, immediate-mode, 2-D graphics API that provides high performance and high-quality rendering for 2-D geometry, bitmaps, and text." |
| • | Improved OpenGL-rendered printing performance and screen throughput with display-list rendering |
