Handy middle mouse button moves shave time and frustration from modeling tasks in Solid Edge ST4
The middle mouse button, or scroll wheel, provides improved model rotation in ST4. You can now select a vertex, edge, or face as the model rotation center. To do this, simply following the steps below:
First you must let the system know that you want to enter the rotation mode. This is achieved by a single click to the middle mouse button (MMB), on an empty space. You will notice the cursor changes appearance. Before you click the MMB your cursor looks like this:
After you click the MMB you cursor will look like this:
Notice that the little blue face, indicating selection mode, has disappeared.
You now have three options available to you:
1. Rotate using a position on a face.
• You can now move the cursor over the face shown below. Notice the dark pink dot, indicating that you are in the rotate mode.
• If you now hold the MMB down, the part will rotate about the dark pink dot. In other words, the dark pink dot becomes your center of rotation.
2. Rotate using a position on an edge.
• You can move the cursor over any edge. Notice the entire edge highlights.
• Holding the MMB down allows you to rotate about the edge. In other words, the edge becomes the axis of rotation.
3. Rotate using a position on a vertex.
• You can move the cursor over any circular edge. Notice the entire edge highlights.
• Holding the MMB down to rotate allows you to rotate about the vertex of the circular edge. In other words, the vertex of the circular edge becomes the axis of rotation.
Note: Once you have completed the rotation, you are returned to selection mode. You will have to single click to the middle mouse button (MMB), on an empty space, if you wish to perform another controlled rotation.
