Hi,

The attached file has an equation error (I cant find the 2 dimension errors D1@Plane2 and D1@Plane3) and a sketch error that I cant fix. I need to do 2 things;

1. Flip the direction of the extrude boss (I need it to be on the other side of the plane)
   1. When I do this the tabs sketch doesnt line up with the solid body anymore and I dont know why that happens
2. Mirror the body around the Right Plane, No matter what I try I cannot get the mirror to work.

I need to know how to fix the errors and then accomplish the 2 items bulleted

Kind regards

Michael Mullineux
