How come my this drawing cannot dimension at the isometric view? I attached my part and drawing here. Thanks.

Install Update 2.2 and try again.

Make sure to use only standard views from the View Cube...

Thanks for your help. My other drawings can dimension the isometric view. Only this drawing cannot. I do not know why. Could you please post this drawing which you dimensioned here? Let me see if I can continue from your drawing. I dimension in my drawing screenshot is as attached.

See this similar thread. You might want to right-click and pick different options before placing the dimensions, or make sure under the styles that the orientation is aligned:

From you latest image it appears that you can in fact dimension the drawing, but the dimensions are skewed?

What about the other two views - do they exhibit the same behavior?

I had trouble with that particular view in your file - same skewed dimensions - so I recreated it being sure to select the corner of the view cube to create a standard view.

The new view worked as expected.

Spacebar to toggle position.

I have no way of knowing what technique you used originally to create this view.

Thank you very much. I created the isometric view from the corner of the cube. When I started a new drawing and repeated the same step, it works already.

I am trying to figure out what could have happened with the original.

Did you install the Updates before your latest tests?

Hi! To properly dimension geometry in an Isometric view, there are two options.

1) Set the General Dimension Type to True (right-click on the view)

2) Annotate the part in 3D. Then retrieve the dimensions in the drawing accordingly.

If you create a dimension on an edge in an isometric view using Projected option, the dimension will be wrong. The length is the 3D edge projected to the view plane at the particular view angle. It is not the true length. Such dimension will change based on the view angle.

Many thanks!

Yes. I did. Thank you very much.

Yes. I installed the update. I think it is due to general dimension type setting.

Thank you very much
