I've encountered on a couple projects recently my files will start freezing when I try and open them after having updated something in my design file where my surface/pipe network resides.
It all appears to be as if something has become corrupt in the design file (where the surface/pipe network resides). The odd thing is, I can open the design file and make edits without issue, but when I then open the grading plan, it freezes trying to synchronize.
I can't figure out what is happening to the files to cause such an issue, as it will be fine and everything syncs properly, then I'll make one change to the grading and suddenly everything takes forever to load or just crashes.
I did notice, on a project, if I copies just some polylines out of the design file into a blank drawing, the file blank file would become rather bloated in size. After wblocking the plines out to a r12 dxf and then inserting that into a blank file, it would be a manageable size again. It's like something is attaching itself to all the objects within the file, which makes reading the file when syncing data references either crash c3d or just take forever to load.
Any thoughts/help on this would be greatly appreciated.
