I need some advice.
The 'application' I am trying to make currently adds entites to a drawing. Each entity has data associated with it but also part of a tree of infomation so I store xrecord data along with the objectID in a dictionary tree within the drawing.
I want to be able to select multiple entities and have any matching data shown in a palette. The same way the properties palette behaves.
I have it working but I can see AutoCAD crunching the data. It cycles through the selection set and the dictionary tree extracting entity data until it finds an ID match in the xrecord.
Does anyone have any thoughts on how the properties palette works so quickly or suggestions on how I could improve the speed.
