Drawing an Arc Between Two Points on a Circle

Hi everyone, I’m new to Seamly2D, and this is my first post here. I’ve encountered a challenge while working on a pattern, and I’d appreciate some guidance.

I’ve created two circles, with centres at points A and C2, and their intersection is at point A1 (as shown in the attached image). Now, I want to draw an arc that joins points A and A1, which should belong to the circle centred at C2.

However, I’m struggling to figure out how to do this correctly. Could anyone guide me through the steps?

Thanks in advance for your help!

You need to find an intersect point at A on the arc. The easiest way is to use the Point - Intersect Arc and Axis tool. Select your arc, select the C2 center point, then rotate the axis line and click on point A. It will create another point at A, but this will cut the arc… so now you will have a segment of the arc from A to A1.

I’ve illustrated below… my point names are different

You can then access that arc segment A3 to A2 length from the varibles.

In this case it’s going to be the shortest Arc_A1 … Arc_A1_8.

Hope this helps.
