Arc Length Dimensions

Post by BarryW » Fri Nov 17, 2017 5:57 pm

Afternoon everybody,
This is probably for Andrew:
I recently worked on a drawing which had been created in AutoCad which contained Arc Length Dimensions. These do not show up in QCAD, (would be good if they did), but, in the return trip back into AutoCad, the Arc Length Dimensions have vanished. Surely, even if QCAD doesn't show them, they should remain on the dwg file and not be thrown away? Is this intentional, an oversight, or a bug ?
thanks,
BarryW

QCAD does not import unsupported entities. I.e. you indeed can lose data on such a round trip.

Much obliged for the speedy reply.
What other dwg. entities are not supported - is there a list somewhere on this site ?
thanks,
Barry

This is a list of entities that are imported by QCAD Professional (note that some are converted into entities supported by QCAD on import).
Everything not in this list is ignored when a DXF/DWG file is imported.

Andrew,
Thanks for that info.
So the bottom line is : If I import a drawing that was created in AutoCAD, I have no idea if some of it is missing !

That's correct. Opening a DXF/DWG file created outside of QCAD always has to be seen as an import with potential data loss.
