Can the entire assembly be mirrored at the same time? If so how would you go about doing that.
Use mirror command in assembly and choose your options.
Yes, See the image below
Select the plane to mirror and the components you then want to mirror
If this assembly is at all complex I'd suggest the following:
1. Start a new assembly (Assembly B).
2. Insert your assembly (Assembly A). It will be fixed by default.
3. Right-click on the assembly in the tree and choose "Float" from the drop-down.
4. Assuming you want to mirror it side-to-side, then Mate the Top and Front planes of each assembly coincident, and then mate Assembly A's Right Plane to Assembly B's Right Plane at 1/2 the distance you want for the Mirror. (If you want to mirror it front-to-back, or up-and-down, then choose Planes accordingly.)
5. Select the Mirror Components function, as in Stephen's screenshot, using Assembly B's Right Plane.
If you'll follow these steps I believe it will create a much more stable model. And I know that if you try to mirror multiple components some of them may be oriented incorrectly, and it may be tedious to sort through the options to get them the way you want. Also, this way you can go back to Assembly A and add/remove components and Assembly B will automatically update to reflect the changes.
