Rotating Elements

 

This task will show you how to rotate elements.

In this scenario, the geometry is simply moved. But note that you can also duplicate elements with the Rotation command. You can de-activate the duplicate mode if needed by: De-activate Duplicate mode.

Rotating elements also means re-computing distance values into angle values, if needed. Be careful: only non-fixed elements are updated.

Open the Transform_replace01.CATPart document.
  1. Click Rotation from the Operations toolbar (Transformation subtoolbar).

 
  1. The Rotation Definition dialog box appears and will remain displayed all along the rotation. De-activate the Duplicate mode, if needed.
    If you keep it active, you will be allowed to define the number of the instances you wish to create in the meantime.

 

  1. Select the geometry to be rotated. Here, multi-select the entire profile.

  1. Select or click the rotation center point.
    You can also enter a value in the fields displayed (Sketch tools toolbar).

  2. Select or click a point to define the reference line that will be used for computing the angle.
     

  1. Select or click a point to define an angle.

 

  • If you have check snap mode in the dialog box and set the value to 5 degrees, then when you drag the cursor to rotate the element it rotates by 5 degrees steps.
  • You can also enter a value for the rotation angle in the Rotation Definition dialog box
  1. Click OK to end the rotation.
    Rotating elements also means re-computing distance values into angle values, if needed. Be careful: only non-fixed elements are updated.

  • Internal constraints are preserved 
  • External constraints:
    • geometrical constraints are killed
    • dimensional constraints are modified and revalued.
