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 “right click” on the line and select “options” 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 tool… not the lenght of the line but the lenght of the movement. (I will share a drawing to Grace)

hi Grace, it’ 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.

Here’s your pattern back :grinning: 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
