I have been working with some metric units lately and have issues with my linetype scale. I have a metric scale of 1:5000, viewport set to 1mm=5M. It seems that the imperial linetype scale, if based on inches originally, would be multiplied by 0.0254 to convert to meters, so 5000 x 0.0254=127 lt scale. But this seems very large in the actual CAD file and does not seem correct. If I set the lt scale to viewport scale of 5, the linetype scale seems more reasonable but still a little small. Does anyone have a suggestion for properly adjusting linetype scale from imperial to metric?
Yes, all the original linework was drawn as imperial, a unit of length was measured as a foot. Now the geometry has been translated to a new coordinate and unit using map3d. Linear lengths do measure properly but may be off a hundredth, I have accepted this level of precision. So a meter in model space is a meter.
1. There is a dedicated forum for MAP3D, you probably ought to post and ask there instead. 2. AutoCAD doesn't understand mixed up units in a file, you must set things correctly: sadly you chose not to answer my question which had you you looked it up would have cleared things up for you. Makes me wonder if I need to simplify my answers for a beginner to help you further? 3. At the command line also type -DWGUNITS ( there is a dash in the name) and ensure your file is now set to meters too after you correctly set what I asked for in my first reply.
Yes, thank you; "measurement" is set to "1" and -DWGUnits is set to 6 for meters. I tried also using millimeters in setting but was prompted for re-scaling geometry. I believe the geometry is good except for the linetype still does not appear with proper line definition, looks solid when it should be phantom2. Should I be using the millimeter setting instead of meters in the -DWGUnits command?
Once measurement is set correctly for metric, AutoCAD should start using the correct ISO version of the linetype file. Reload your linetypes in the file with LINETYPE command (actively go into the ACADISO.LIN file, select all and answer yes to reload all linetypes). Then get back to scaling it like you do in all your other metric files. There is no need to switch to mm if you regularly work in and need meters.
That worked if I am not using a custom linetype file, ours is acad.lin from the imperial version. What is the best way to convert that file to be metric?
