Dimensioning in Paper Space

antwaneolee — Sun, 06 Mar 2022 00:42:42 GMT

I am having problems dimensioning a drawing in paper space. The drawing is from a 3D model in model space, but the viewport is a 2D 'Right' elevation on the paper space sheet. Sometimes it gives the correct dimension and other times not. I tried manipulating the OSNAP settings with minimum success.

Please provide feedback.

Thanks.

Post a dwg file please which which contains an example of both of them, so we can see what you're doing.

Please see the attached dwg/drawing file with dimensions. The dimensions at the top left are incorrect.

Please review.

Thanks.

Your viewport doesn't have a proper scale.

Make your viewport scale 1/2" = 1'-0".

IMO it is a bug in AutoCAD. It is not possible to add correct dimensions in the paper space to 3DFaces. I can repeat this wrong behavior in newer AutoCAD versions too.

For the moment I'd suggest to create the dimensions in the model space (and scale them with an annotative dim style). Doing this you need a correct scale factor in the view port(s).

>>Here<< you can see how that can be done.

BTW: I'd suggest NOT to use the Defpoints layer for the viewports (it is a special layer for internal purposes). Rather that create a separate new layer and set its "no plot" property.

Another possibility to get correct dimensions, if you urgently want or have to create paper space dimensions, you can see >>here>>.

In short words:

Convert the 3DFaces into Surfaces (convtosurface command).

Before you should set DELOBJ to 3 (to delete all 3DFaces) and can set SURFU und SURFV to 0 (to avoid the lines inside of the Surfaces).

I will try.

Thanks.
