Hi,
I've got an existing Hevacomp model which works fine in CAD input.
But I need to update the DXFs and change a couple of zones. When I bring in the new DXF all the CAD rooms on the floor disappear. The rooms are still there, because they show up in the 3D view and and I can bring them up using 'find room'. However, when I do this, the DXF disappears form the view.
Is there any way of correcting this?
DXFs are lined up with the previous DXFs, and set to the same scale.
I've tried clearing the chache of the old DXF links, but this hasn't fixed the problem.
DXFs have different names to those used previously. But there is no way of avoiding this, because previously one DXF was used for multiple floors. Now, each floor is different and so needs a different DXF for tracing.
Any help will be gratefully received.
Thank
Hi James,
Everything you describe should is spot on - clearing the DXF cache and having new DXF filenames is perfect If the scales and origin point are the same then the only other thing would be that perhaps the new DXF has stray elements causing this.
Sometimes if there are elements (ie lines etc) very far away from you building plan this can affect the positioning and scaling of the drawing. Could you do a select all in your CAD software and check this?
Also good idea would be to trace a test room (ie in Hevacomp) over your updated floor plan, and then zoom all. The size/location of the other rooms should then become clear.
Regards,
