Add a line to make a triangle. Select the triangle and use the Offset tool. Draw lines connecting vertex to vertex. Bingo. An automatic function is beyond me.

How do I find correct spot on triangle to draw circle so all three sides of the triangle touch the circle?

I would like to find the spot on the face of the triangle so that when I’m sizing the circle the circle will fill the triangle so all three sides of the triangle touch the circle at once. I have tried different things, including google. But I’m probably making it harder then it should be or simple don’t know the correct terms to search for. Here are some stupid things I have been trying. [image]
