I run into this issue often and never seem to have an elegant solution to it. I was hoping someone might have a good idea as to how to deal with it.
I need to cut out the top and bottom plate for a curved knee wall. The plates will not fit onto a 4x8 sheet of plywood, so I want to divide the arc into three equal arcs and then nest them on a sheet of plywood. So I have my arc drawn as well as the two lines dividing the large arc into three equal arcs. The problem is the lines that divide the arc actually need to be two lines, one for the edge of one arc and one for the edge of the arc next two it. So when I break out the snipping tool I have to do all sorts of cut and paste to duplicate those vectors and end up with three separate arcs that I can nest.
Is there an easy solution that I'm not seeing?
Thanks

Re: Divide an area and separate vectors
Easiest way I can think of is to copy all the vectors to 3 different layers, one for each of the pieces you're making. Then you can just easily bring up each layer in turn and snip away the stuff you don't need for that part.

Re: Divide an area and separate vectors
In such cases, I use Steve's method except I duplicate to a total of 4 layers, and I keep one unchanged as a reference. So if I realize I have to change something, I delete the copies, modify the reference and restart the process. Otherwise, the original design is lost.

Re: Divide an area and separate vectors
The way I would do it is to use node editing. In node edit point to where an angle line and the curve meet and press C to cut the vector. Repeat on the outer/inner intersection. That will give you two open ended curved sections. Select one and use the Join with Straight Line tool (click the icon or choose it from the right click menu). Repeat on the other section and then repeat those steps for the other intersection.
One of those that takes longer to write about than actually do.

Re: Divide an area and separate vectors
Thank you for the replies and ideas.
I will experiment with them and I'm sure I will be able to get the job done quicker and easier than the way I'm doing it now.
Your help is much appreciated.

Re: Divide an area and separate vectors
Dear Keith (and others watching)
Here is my two-penneth - click images to enlarge
We use this a lot for our curved seating
(01) Firstly Steve and LGM are correct 'make copies' But see (03) (02) When you use the trim vectors tool there is a tendency for the 'curved vector' to 'spring' off line. This is only a small amount and may not be an issue. But if it is an issue (03) (03) Use Node Edit - Zoom in on the intersection of the lines to be trimmed and insert a node on the intersection particularly on the curved line - but I do it on both. (03a) Occasionally the inserted node 'moves off' the intersection and you need to insert an other (04) Only when I've inserted all the nodes I require do I 'make copies' and start trimming
Anyway that’s how I do it
Sincerely and in good faith
Martin

Re: Divide an area and separate vectors
Why insert nodes and trim? You can cut by hovering with no need to use the trim tool or insert nodes.

Point taken... Force of habit.... and I like to let the trim vectors tool rejoin the trimmed sections.
