I currently use a class library that contains various class modules used to draw shapes in AutoCAD. They currently create LWPolyline entities but I'd like to modify them to create block insertions instead. The reason for this is that there may be several hundred instances of the LWPolyline entities created by a given class module in a drawing. By making it a block insertion instead, If the end user has to modify a specific shape because the customer has decided that a dimension should change the user can simply redefine the block in the drawing rather than having to modify each individual LWPolyline created by that class module. Here's the tricky bit. If we consider the simplest class module having the following properties: Length, Double Width, Double RotationAngle, Double Mirrored, Boolean (I fully intend to remove these 2 latter properties when converting the object to a block insertion.) If my application creates a block insertion name MyInsert with the following values: Length, 5.0 Width, 2.5 RotationAngle, 0 Mirrored, False then any block insertion created by the same class module with any other values than these would require a different name so that these insertions would not be changed when the user redefined the block definition for MyInsert. I'm thinking of creating the first insert as MyInsert1 while adding the class property values (stored in a collection) into the dictionary. Then I can check the dictionary everytime the class module creates an insertion object to see if it has different properties than any previous entry with a 'MyInsert' prefix. If any property is different I would then increment the suffix of the Block name and create another dictionary entry. Question: Any suggestions? Is there a better or easier way to do this that anyone can see. Is the dictionary the right place to do this? Best regards, Dale-
