When adding sketches to a drawing (for dimensioning bolt hole circles) scale is off.

Leo_Dyn — Tue, 19 Apr 2022 23:05:01 GMT

As I mentioned in title, when adding sketches to a drawing (for dimensioning bolt hole circles) scale is off.

What I am doing: placing views as normal. Then using the sketch command within the drawing to place a circle through the bolt hole pattern. When attempting to place a dimension on this sketched circle, it does not work UNLESS the view is at the 1:1 scale. Any other scale and the dimension is off by that scale factor.

Am I missing something? As in, is this a bug, or is this just not an intended use?

If not the intended use, what would be the "correct" method to showing a bolt hole circle dimension in fusion360?

Please attach the MODEL you are creating the 2D Drawing from so the Forum users can see what you are doing. If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Edit: I am puzzled why the Centerline Pattern drawing tool will not do what you want so you can skip the model sketch?

Hi! At the moment, the drawing sketch geometry is measured as the paper length. There isn't a scale factor applied to it. If you want to dimension to the sketch geometry, you will need to override the dimension value manually.

Many thanks!

Sketch in Drawing workspace is definitely not the right tool to do this. It is not even associated (e.g. doesn't get updated with the design). Either add the sketch in Design workspace and make it visible in Drawing (Sketch folder must be visible first), or even better and much easier; follow @jhackney1972 's suggestion to use Center Mark Pattern:

"Center Mark Pattern"

Ah!! Thanks, so much, didn't realize this was there! Exactly what I need!
