Dimensioning Arc Length in Paperspace

Pascoe_Design

I am doing a tube bending drawing and I usually dimension the radius, angle & arc length on tube bending drawings.  strucggling to work out how to dimension the arc length of the centreline in paperspace... Can anyone help?

@Pascoe_Design - Great question!!!!

So there is a document that shows how to so this . . . 

https://cad.onshape.com/documents/673f5cf242983544f53711c8/w/4d091d8d8fd2881173d137e7/e/7f37e05e0571eb701a16b94d

But it involves a number of workarounds.
My ask of you is where these workarounds are 'needed capabilities', please as a Professional user, submit feedback tickets requesting the specific improvements.

Steps:

• In the Part Studio, I created an additional sketch (the additional step is because i wanted dashed lines in the drawing and i cannot sweep along dashed lines).
• Natively in a Part sketch, i can annotate the arc length (click each end point and then hover over the arc).
• In the drawing, insert a view of the part.
• Also in the drawing, insert another view that is just of the sketch. This second view is a work-around - the enhancement request would be the ability to insert multiple things into the same view OR a way to tie the two views together (I just eye-balled it).

• Next - detail the sketch a you normally would (other than the arcs). We do not currently support the dimensioning of arc length - please submit an enhancement request (via the Feedback tool). To detail these, i used a note-with-leader and typed in the arc length (copied from the sketch). There is an 'arc-length' symbol available as part of the annotation drop down so that works.

I hope this helps you - Philip

You don't need the additional sketch and the sketch view in the drawing.

You can create a few edge to edge centerlines in the drawing and move the end points of this centerlines, so it looks like a single curve.
And then you can create the dimensions as you mention before.

Eduardo, thats neat, but the dim is still manually entered right? (just checking that i am not missing something)

Yes, the dimension is still manually entered exactly as you mentioned before
