Currently if a custom shaped linetype is exported to AutoCAD, ARCHICAD will create a linetype that has all the segments of the linetype in one shape definition. The disadvantage of this is first that in case of polylines AutoCAD will display the shape in a kind of unpredictable starting position, the second is that if the polyline or line segment is shorter than one segment of the special shape, then it will not display anything even if one or more arcs of the shape would fit into that segment.
With matched AutoCAD linetypes
This example describes the export of ARCHICAD's built-in "X" linetype to DWG, but the same steps can be used for every symbol linetypes.
Step 1. Create custom AutoCAD Linetype
At first step the same (or similar) linetype should be created in AutoCAD which can be the used ARCHICAD linetype convert to.
Open a text editor program that saves in ASCII format (for example, Notepad)
Paste the following rows which means the description of a continuous line with X signes:
Save this file to *.lin (AutoCAD linetype) format, e.g. X_line.lin
NOTE: the default AutoCAD linetypes are stored in "acad.lin" or "acadiso.lin" Linetype Definition files (e.g. C:\Users\Username\AppData\Roaming\Autodesk\AutoCAD 2010\R18.0\enu\Support), the linetype definition can also be pasted into these files as in our example.
Step 2. Load the created linetype and save to DWG
In AutoCAD open Linetype Manager and load the created or the modified (acad or acadiso) .lin file. The new "X_LINE" linetype will appear in the Linetype list.
This linetype can be applied to existing lines in AutoCAD or it can be used as a template file.
Save the file as DWG.
Step 3. Set Linetype-conversion option in ARCHICAD
