Shift+Drag and CTRL+Drag do not work?

Occasionally, you cannot Spin or Pan your model with the SHIFT+Drag or CTRL+Drag, keys on your keyboard.

There are two possible reasons:

A.Your mouse-pointer is above an element (e.g. a Plane), before you press the SHIFT or CTRL DE: STRG key.

Make sure your mouse-pointer (cursor) is not above an element before you Mouse-Button-Down to start to drag or pan.

B.A bug - MechDesigner just stops responding to the keyboard and mouse controls as we expect.

We cannot find why this happens.

You must re-start MechDesigner.

Note:

We recommend you press the left-arrow, right-arrow, up-arrow, and down-arrow keys on your keyboard to Spin the model by 10º each click (or Shift + Click = 90º , Ctrl + Click = 30º)
