Drawings: How to dimension angle between arcs?

[r.moss]

I have a curved sheet made with three sections of different radii.  In the original sketch I drew construction lines between the arc centres and the blend points and set the angles between those construction lines.

How can I show those angles on a drawing?

Really I need to be able to put points at the arc blend points and then draw construction lines between them and the centres, so I can measure angles between those lines.

Alternatively (maybe better) it would be nce to dimension arc lengths between the blend points.

(PS.  I have heaps of dimensions that need to be re-associated - that will be another post).

when you need a dimension that isn't easy/possible to achieve with the dimension tools in the drawing space, you can create geometry as a sketch in the design, turn that sketch on in the drawing, and dimension to that.  you un fortunately may need to leave the sketch on in the drawing view after you dimension. so I usually create a separate sketch in the design with just the sketch elements I need for dimensioning.

Thanks, that's a good tip.

Construction lines are not visible in a drawing (and sketch solid lines become dashed, like a centreline) so I need to convert my construction lines into solid but that's no big deal.

My next challenge is to dimension a skew-ended pipe .   I don't think there is any way of adding dimensions apart from making a table of angles.
