I'm struggling with dwg export to (mainly) Autocad. I'm trying to export correct units and linetype scales, but unfortunately I can't get them both working together at the same time.
My assumptions (Archicad):
Working scale: 1:100
Drawing scale on layout: 1:100 (100%)
Drawing units: cm
Save layout into: Model Space
As You can see in my example:
1) Autocad v1 has:
a) wrong scale (1 unit = 0,1cm)
b) good linetype scale (spacing)
2) Autocad v2 has:
a) good scale (1 unit = 1cm)
b) wrong linetype scale (spacing)
Also changing the "Ltscale value in output File" to 10,0 or 0,1 in Archicad translator doesn't change anything visually in dwg because somehow Autocad "Linetype scale" is hardcoded into 0.1 because of Archicad scale 1:100.
This will show you how to map the linetype from Archicad using a template AutoCAD file. Remember, AutoCAD stores linetype and color information by layers, so what we need to do is create some custom linetypes by layers and match them with Archicad's linetypes.
I hope this helps with your issue!
