Best way to split a polygon keeping the common curve on both sides?

Hi all,

I have to do this action a lot. Whats the best way to do this?

The method I currently use takes quite a few steps:
1- draw cutting line
2- split command
3- join curves of left side
4- redraw cutting line on right side
5- join right side

I’m hoping there’s a faster way

You can offset the cutting line (sketch the cutting a little bit longer) in both directions a then trim arc and offseted curves

I want to split the object and not lose anything.

Why I need this: I work with CNC machines, to stay within the limits of our machines I often need to divide the objects we need to make.

Hello - use CurveBoolean for this.

You can use CurveBoolean its very simple but you have to change all the horrible default options to this.
DeleteInput=All CombineRegions=No Output=Curves AllRegions

If you like the way you currently do it but want to speed it up you can do that as well…

1- draw cutting line (select it and CTRL+C to copy it)
2- split command
3- join curves of left side
4- CTRL+V to paste your curve (no need to draw it over and over just copy paste!)
5- join right side

you can assign those options to the right click on the icon of curve boolean, @pascal should know how to write it better.

I already did try CurveBoolean for this, it works a little bit better. But was hoping there would be an even better function I missed :slight_smile:

Thats actually the method I already use. But whenever I need to use copy/paste like that, it just feels sloppy to me… I’m always looking to improve whatever I’m doing :slight_smile:

Hello - this seems pretty straightforward -

To make things even quicker (no command line options to choose) make a macro:

! _CurveBoolean _DeleteInput=_All _CombineRegions=_No
