Dimension an Arc length in Drawing

  I do not believe there is a way to do so in a drawing.  When you are in a part studio, using the dimension tool, you can select the two end points and then the arc to figure out its length.  However, while you are in a drawing file, the dimension tool will only give you the radius or angle.  This might be a feature that is not added, so it definitely would be useful to have.

  Required to have.  I bought the service to make drawings specifically for arc lengths. Oops

  Have to add my vote for this. I'm finding dimensioning in drawings quite challenging in general. There are a number of workarounds for other issues but curve length does not appear to have one. I'm not sure what to do here. Need to communicate the arc length to the fab shop. I can put a comment/note on there but then if/when the design changes...

  Still not sure how it is 2025 and a seemingly basic tool for accurately dimensioning drawings has not been implemented. Hoping this gets added very soon.

  Feels like some smart person could do a feature script to allow it to be dimensioned in a sketch, then the sketch could be shown in the drawing,

  The improvement request is here:

  Well, 5/13/2025, and I need to show "a dynamic" arc length on a drawing.

  as Stan Lee would say, "nuff said".

  @NeilCooke
  Dear Neil,
  maybe you can enlighten us with this question.
  In sketches it is posible to dimension the length of an arc.
  But in drawings it is not.
  
  How can we solve this issue?

  Thanks for your response.

  @c_büscher The development work for arc length dimensions is in progress for drawings. It won't be possible as you want until we deliver on that. Currently most users call this out manually with a note.

  I'm throwing a comment in here - and a request for Arc Length dim for drawings please.
  I can appreciate manually creating a call out with a note for the time being - with the disclaimer that its not robust and can cause issues downstream in manufacturing if design changes are made an it is not manually updated.
