Hi,
I would like to align (snap) to objects that have different angles. Basically I have a geometric figure (a triangle) and I would like to add a rectangle to its border, but I'm not able to match the angles. Any idea ?
Thank you for your help

Hello, and welcome to the forum.
You could either…
Create your rectangle along a line.
On PC hold down the Right Mouse as you drag the rectangle, and ensure that you are snapping to the corner nodes of the triangle. Then resize the rectangle as appropriate.
Or…
If you install the new 1.7 beta, you can use the new Point Transform Tool to drag your rectangle onto the triangle. Then resize the rectangle as appropriate.
