Dilation

You can dilate any subset of your diagram from a point. Here are the steps:

1. Select   the geometry to be dilated.
2. Click the Dilation tool   in the Construct toolbox, or select Dilation from the Construct menu.
3. Click the cursor on your dilation point.
4. In the data entry box presented, enter the dilation factor.

The dilated geometry appears.

Notice all points on the dilated geometry are written as "prime", i.e. A becomes A'. If you dilate this geometry again, A' becomes A".
