Good day I am trying to mirror the 2 consturction circles at the bottom of this extrustion to the top of the extrusion so that I do not have to re draw the 2 circles. But when i use mirror program places it above the face.
If you want to use mirror, you have to create a plane exactly to the middle of the body. When you select a plane in mirror tool, you select where a mirror would be, not the target.
You can use the Project tool instead, and project the circles to the top face.
Alternatively, you can select the circles, and move+copy them by exactly the height of the body.
