Opening .dwg file questions

[Carl_Mesrobian]

I have some old .dwg files from my AutoCAD days, and want to get them into .3dm format, and have questions about dimensions. The .dwg dimensions are larger than the Rhino dimensions, and I’m curious why.

Maybe this is a good one for @mary Here are screenshots

I did a “what” on the AutoCAD dimension:

This is the dimension from the .dwg file:

I did a linear dimension command and this appeared (small one in black):

This is “what” of the Rhino dimension:

In “what” info the text heights and scale seem to be the same, so why are they scaled differently in model space? “MatchProperties” doesn’t change text size.

Thanks for any help

If you want any files, just give a shout - thanks!

Typically turning off layout scaling will resolve this, another good method is to SelAnnotationStyle and change to a native Rhino style.

An example file would help us understand what you are seeing.

Layout scaling is already off. I’ve exported the dimensions in a .3dm file.

The Annotation Style shows model scale as 1.000, but the font is 4 times .0938, instead of .0938.

When you double click the dimension, it shows scale of 4.

After changing that,

it becomes the right size.

For what it’s worth, I just tried opening a .dxf, and once I changed the annotation settings (font, arrow, leader arrows), it worked fine.

Maybe just a .dwg thing??

The blue highlight indicates this is an override, which must be coming in from an Autocad setting that dxf doesn’t support.
