PDS:Arc Tool

Create an arc as an internal contour or use it to reshape a selected segment. This tool is commonly used, as it allows easy reshaping of segments such as Armscye, sleeves etc'. There is also an option of reshaping two pieces at-once, in cases such as a tailored sleeve that 'shares' the same curve.

Number Of Points Along Arc

Set the number of non-grading points that will 'support' the arc. 'Number of internal points' by default is 9. If changed, the system will remember the last number used. Basically. this field should not be changed, but if changed, make sure to write an odd number – like this there will be a non-grading point exactly in the middle of the curve.

18. Arc with 3 points along the arc

Radius

Set the radius of the arc.

19. The radius is 5cm. Note, that in the example, in order to get the correct circle, the Circle By Three Points Tool was used

Distance

This value can also be seen when pressing Shift key , and the center point is shifted. The distance from the original curve's center is marked.
