Surface Modelling - Surface Associativity Integrity Error

Hi,

I have these blocks that I use which work perfectly in Autocad 2012 and 2014. Basically you can edit certain properties of the blocks (like length, width etc.) and the block changes accordingly. However, with Autocad 2015, when I try to use the same blocks I get the an error. I have attached a screen shot of it to the post.

When I click OK, I can still keep the block in the drawing, but it doesnt alter its appearance as I change its various properties.

These blocks can also be viewed in 3D.

Thanks in advance for any help!

Can you attach a copy of one of these blocks to your next post? I'm running AutoCAD 2015 so I can test it.

Hi ReMark,

Thank you very much for your reply. These are blocks that I actually use for work, so I'm not sure if I should be posting them here. Will check and see.

However, what I can tell you is that since I posted, another block which was working perfectly now displays that same error and doesnt display the block properly when I insert it.

The blocks are basically conveyor blocks. With the latest block that is causing problems, when in top view 2D, the conveyor block doesnt display properly. Certain sections of its are missing (its like a dashed line). But then when I change the view to an isometric with 2D wireframe, the lines are continuous.
