Title: Creating Static Block of iinstance of dynamic block
Post by: cmwade77 on March 11, 2024, 07:57:49 PM

I am trying to work around some issues in CAD, so I am trying to create a static block of an instance of dynamic blocks. I have code that mostly works with this jig until I click to finish the the rotateresize jig as attached, then it throws a system exception error because it tries to copy the block again. I am using the attached block as well. I am close, just not sure what I am missing.

Hi,
What about using BlockReference.ConvertToStaticBlock (https://help.autodesk.com/view/OARX/2023/ENU/?guid=OARX-ManagedRefGuide-__OVERLOADED_ConvertToStaticBlock_Autodesk_AutoCAD_DatabaseServices_BlockReference)?

Your CreateBlock method could be something like this:

Code - C#: [Select]

1.         private static void CreateStaticBlock(BlockReference originalBlockRef)
2.         {
3.             var db = originalBlockRef.Database;
4.             using (var tr = db.TransactionManager.StartTransaction())
5.             {
6.                 var blockTable = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
7.                 int i = 1;
8.                 string newName;
9.                 do
10.                 {
11.                     newName = $"Nested_{i++}";
12.                 } while (blockTable.Has(newName));
13.                 originalBlockRef.ConvertToStaticBlock(newName);
14.                 tr.Commit();
15.             }
16.         }

And this method should not be called in the Update method of the RotateResizeBlockJig. It should be called in the InsertBlock method instead.

Ah, my bad for not more clearly explaining what I am trying to do, I am trying to work around some issues in how jigs work with dynamic blocks. Basically, I am dynamically updating the properties of the block, creating a new block that contains that block as an entity, then erasing it as the mouse moves. It works smoothly this way, until I finish the command. I know I have seen this approach before on a website (it's what gave me the idea for this approach), but I can't find it now and so I am trying to recreate it from scratch.

I actually have figured out a better way around the issues by making the original block not visible, setting the properties, then making it visible again seems to work.
