# Collar facing by moving a curve

I try to make the facing of a collar. I moved the collar-curve 2,5 cm perpendicular, but the curve is obviously too short. how can I extend the collar facing line?

It all depends on how you are drawing your collar. perhaps you can share the .val and .vit files so that I can see. Which pattern making system are you using? What do their instructions say?

to extend the length of a line, you should be able to â€śright clickâ€ť on the line and select â€śoptionsâ€ť from the resulting pop up menu. In options you will see the length of the line and you can replace it with a new value. Grace can probably help you with making the length be a formula rather than a simple value so that you would not have to extend this manually.

Thanks kmf, but when I select options, the options are the ones from the move toolâ€¦ not the lenght of the line but the lenght of the movement. (I will share a drawing to Grace)

hi Grace, itâ€™ s a very simple shirt, that I copied from a real shirt. so no patternmaking system. I hope the facing.val makes it clear. thanks in advance. facing.val (13.7 KB)

Is this what you want to do?

I added node A18 at 4cm from the end of the curve Z1-A4 using the segment a simple curve tool (Spl_Z1_A4-4). Then I added the node A19 using the point at distance along line tool from A2 to A8 and the formula Spl_A18_A4+2 (which is the distance of A18 from A4 and added 2cm to get the V nicely).

I then drew the simply curve and used formulas for the angles and lengths of handles.

Now, if you change the -4cm at the end of the formula, the whole curve will move accordingly.

Hereâ€™s your pattern back now you can see if you can do the same for the back neckline.

hi Grace. [I apologize for the late reply] thanks for your instructions. I guessed there would be a more exact method to make a parallel curve, but your method works more than good enough. thanks again, Anna
