Civil 3D – Point Style File Size Issue

If you hadn’t noticed (I didn’t), the size of your Civil 3D 2009 drawing will change depending on style factors. 

A buddy of mine questioned me yesterday about some substantial differences related to the size of the drawing he was using, and noted that while he saved his site plan with trees (point styles) on, the drawing was twice the size.

I just tested it.  I took a huge site plan, and saved it with trees on, and saved it with all point styles overridden to standard.  Sure enough, I got a 30% reduction in size.

It appears that the application does not treat the Point style blocks as it treats normal blocks.  Normal blocks are place holders, an entity shell that contains the standard DXF table entries for location, scale…….etc, and then upon regen, it goes to the block table, and pulls the information to display it, where the place holder says it should be.  Instead of saving 40k 1000 times over, it stores 1 40k reference, and stores 1k 1000 times. 

However, for point styles, it appears as though the application is treating the drawing as if it had 1000 different entities, and is storing all the reference information at each point location.

If anyone has additional input, please comment. Christopher, James, Dana, that means you!
