Import DWG with original lineweights

Dalius — Fri, 20 Apr 2007 12:27:36 GMT

DWG import is a real headache...

When I save Archicad file as DWG, the drawing opened in Autocad has original lineweights. However when I open Autocad DWG file in Archicad, the drawing loses original lineweights and all the lines become 0.18 weight.

My question - is it possible to import DWG into Archicad with original lineweights? If yes, then which option of the DWG translator I should use in that case if I don't know what colors and lineweights where used by Autocad user? In other words, I need to open any DWG file in Archicad with original lineweights.

Many thanks for your comments and any help!

I think this is not possible!

Autocad has two ways of assigning lineweight information - by layer in the Layer Manager and in a separate file. In the dwg file there is information only about the first way. So, quite reasonably, AC just ignores this half-information.

You could ask your colleagues to send you dwg files with the lineweight file, but my experience shows that most of them have never heard of this file!

If you know the lineweights/colors you want, you can set up a pen table and apply it as needed. Since ArchiCAD works with multiple pen tables in each project this is really quite easy. It is a pain though if you have to do it often for many different consultants' files. But then most people don't use that many pens and AC can show only the pens used making it fairly easy to tweak them.

CTB or STB?

Thank you for your comments.

As I understand, it is impossible that DWG file could be opened in Archicad with original lineweights if I don't know what lineweights where used in Autocad?

Yeah, this is the question!

If you open the file on another computer, even Autocad would not know!

It will, with eTransmit/Pack&Go ...

... but most of the users don't know about it anyway ...
