I have been sent three drawings from a structural steelwork fabricator who used
the StruCAD program .
He saved the drawings in the .dxf format and then zipped them up and sent them
to me.
I have recently started to use the AutoCAD 2004 LT application.
I unzipped the .dxf files and opened them up in AutoCAD.
Then I saved them as .dwg files.
The .dwg files are completely out of scale in model space.
When I do a distance enquiry on the known distance between two pairs of
intersecting grid lines instead of getting 3892mm I get 59.xxxx on one of the
drawings and for the same pair of intersections on one of the others I get
55.xxxx.
I can of course 'correct' these drawings using the Scale command.
But I would have thought that in the process of going from the original StruCAD
drawing => DXF => DWG, AutoCAD 2004 LT would have been able to keep the
accuracy over the changes.
The dimension of 3892 is correctly drawn in the StruCAD drawings as it would
have to be since this is used in the fabrication of the steelwork members.
Is AutoCAD able to do this or must one 'correct' the scale every time you
receive such a 'delivery' of StruCAD work via DXF?
Apparently, and according to the StruCAD technician, you cannot get DWG files
from that application.
Any help or comments appreciated.
