Hello there,

I am currently struggling to add a construction plane that is parallel to one of the main planes and touches the edge of an extruded circle (see picture).

 ![constructionplane](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/3X/1/1/119cf7a2e3145e70fe26dbb1172d797df390c469.jpeg)

I thought about using the offset face option, but for this I would need to know the coordinates of the centre point of the circle, which I do not.

How could this be implemented? Thanks in advance!

You can create a construction sketch at the radius of the cylinder, and create a construction plane that’s perpendicular to the sketch.

It worked for me by creating a construction plane using “parallel to face at point” with the centre point of the cylinder and then moving it with the value of the radius.
