The physical seam allowance in a pattern piece in an imported DXF file is shown by an internal line. To remove this seam allowance, we do the following:
-
Select an edge. The selected edge is highlighted.
-
In the Context view, under Actions, apply a negative seam allowance - equal to the amount of the existing seam allowance material.
-
On the keyboard, click Enter. The seam allowance is removed.
We are going to apply this technique to our pattern pieces, starting with the collar, then the sleeves, and then the front and back pieces.
Tip
In the tutorial, the seam allowances are known. If you receive a DXF file and do not know the seam allowances, you can use the 2D measuring tape feature to measure the seam allowances. For more information, refer to 2D Measure.
Once you are ready, continue with Dealing With the Collar.
