It might be worth posting any questions relating to this into the main forum as monitoring of posts such as this are minimal.
oh sorry I have replied to the wrong person?
I am using open buildings update 5, I create a 3D model, reference this model into my drawing sheet model space. create sections from the model with drawing production and then create 2D drawing models from these sections, I annotate these sections then reference this into my sheet.
if the model is too far away from 0,0,0 (real world co-ordinates) can this affect the display and printing? I am finding that what I see on the screen doesn't print to my hard copy?
