Syntax : (entupd ename) ename - a valid entity name returned by entsel, ssname, entlast, or the entnext function. entupd - Updates the screen image of an entity.
Googling for CommandAsync I only found 3 examples: a thread on Kean Walmsley's blog, another one from AutoCAD DevBlog and a code sample on GitHub. (entmod elist) updates the AutoCAD database and replaces the old layer name with the new one. NET, AutoLISP, and other techniques.While.
In previous articles in this programming series, we have explored how to customize AutoCAD-based products using Visual Studio.
Roe Customize AutoCAD Electrical and other software products that lack a. The docs about these methods are more than laconic: " This is Command, a member of class Editor." Program AutoCAD-Based Products Using AutoLISP 18 Mar, 2015 By: Andrew G. Note that these methods are no longer available. AutoCAD uses the 420 value, so the code 420 value should be removed before attempting to. These method replace the need to P/Invoke acedCmd() or call the non-public Editor.RunCommand() to synchronously run AutoCAD commands.
