2d plot using distance between points only?

Sounds like a simple ask - but I can't find software to do it.

It would be possible to use maths to derive the position of each of the corners - but then I'd have to do that for every trangle and plot those points - but it would be really painful.

The other way is to do it as you would on paper:

1. draw the first line A-B
2. plot a circle, centre A with radius of the second length A->C
3. plot a circle, centre b with radius of the third length B->C
4. the intersection of the circles is point C

I'm not sure how to use the cad packages I've found to do that.

That's CreoElements .. the student version is free .. but you can use FreeCad use https://wiki.freecadweb.org/Draft_Line for the circles. Out of that you than need to make a technical drawing .. the circles will not apear there than .. Using meassurements you can add the lengths you don't know .. when it's more than necessary Creo will use "Reference" for them.

Piglet:
Thanks.

I'm giving qcad a go. That seems to be fairly intuitive. It's very quickly shown that my measurements need re-doing!

Blub:
I cannot help with the task, but I'm curious what kind of a project you are planning here - adding more space to Pork Castle? :o

Piglet:
Nothing that exciting.

We have an odd shaped plot, and want an accurate scale map of the house and garden.

Qcad seems pretty good. I can draw it out with that as I'd have done it on a drawing board....but I can always correct mistakes without using an eraser!
