• Converting DWG-DXF Colors And Line Weights

The Translator import and export functions differ a bit.

When you open a DWG in ArchiCAD, the translator converts the colors to correspond to ArchiCAD, but because ArchiCAD has pens matched to colors, the lines have ArchiCAD pen weights. This is useful to match to ArchiCAD drawing standards.

When you export a drawing to DWG, the translator converts the colors, but the lineweights will correspond to the AC values, and not to the values in the table. So lineweights in the Translator dialog take no effect to the generated DWG. Now it's seems like you cannot set different lineweights as ArchiCAD defaults.

The easiest way to set different Lineweights as in ArchiCAD to assign lineweights to layers or colors.

To simplify the process in AutoCAD:

- If objects require identical lineweight by layers, check the Set All Elements' Colors To BYLAYER box in Translator Setup > Attributes > Pens and Colors > Methods tab. When you open the file in AutoCAD, you can set the lineweight using the Layer settings dialog.

- If you want to assign lineweights to colors, save the DWG using ArchiCAD colors. When you open the DWG in AutoCAD you can select the elements by color, and set the object lineweight or you can create a Plot style table, which is a table that contains parameters used by printing/plotting. Here you can assign pen weights to the corresponding colors.

Note: Plot styles take no effect to the display of the objects on the screen.
