New nesting tool ...
Wow - that's is already looking very neat. Thanks for working on it.
1. Question: Quantity,
If I have only one part but need to nest it e.g. 50 times then I have to put 49 copy's into my drawing. Would it be possible to tell the nesting tool how many of that part are needed to be nested?
2. Question: Meaning of "Not placable"
If I have 10 parts, start the nesting tool, choose a solution with the alert "Not Placable 1" then the tool will still nest 10 parts. What means "Not Placable"? This test drawing has no duplicates or open contours ...
3. Question: Option for "Move and copy,
If I prepare a nesting and apply the nesting solution the selected parts are moved into the frame. That force me to prepare my drawing just for the nesting task or I will loose my drawing arrangement.
If I could tell (option) the nesting tool to move and copy the selected parts instead of just moving them then I could keep my original drawing untouched - except of visibility of layer etc..
BTW: Many DIY people are using a paper print to transfer shapes to the material (clue on). With my mentioned option, the powerful print preview tool and/or the Paper_Space functionality are then the perfect tools to be able to keep everything as usual in one drawing.
Yes I know, you could use undo but in that case you will loose the nesting and for every additional nested paper print you have repeat that task ...
4. Question: Nesting only for QCAD CAM application?
I know that it looks like the nesting tool is today only interesting for CAM processing but the old school processing needs nesting too. Only a fool doesn't cares how to handle the resources like e.g. a plywood sheet with the best possible outcome to keep the project cost acceptable. And not every QCAD Pro lover use the QCAD CAM solution for different reason.
Any chance to get the nesting tool in QCAD Pro too?

Re: New nesting tool ...
Yes, maybe in a future version.
It means that some parts were not nested. Not sure what was wrong in this case.
Good idea, yes.
The nesting module may not seem like much but it's actually quite an addition in terms of effort that is behind it. So it's more a pricing decision rather than a question whether it would be useful to QCAD users. QCAD users can always resort to other solutions available such as deepnest.
Re: New nesting tool ...
Thanks for your response.
I never doubted that.
I understand your train of thought but think about all scenarios.

Re: New nesting tool ...
Trying to understand the tool ....
If my alignment is Left-Bottom why is a solution offered Right-Top?
and BTW: Every alignment option exist twice in that list ...

Re: New nesting tool ...
I cannot reproduce that here. Perhaps attach the file? It's also odd that you are getting 1 non-placeable part. Can't reproduce that either.
"Left - Bottom" means align left with first priority, bottom second priority.
"Bottom - Left" means align at bottom with first priority, left second priority.
For examples that show the difference, please refer to:

Re: New nesting tool ...
Could it be that you are selecting the sheet as well as the parts? It looks like it in the screenshots. That would mean that the sheet is also a part. It would certainly explain the 1 non-placeable part
When doing that, I can reproduce the weird alignment. Let's just say in that case the behavior is "undefined". I.e. do not select the sheets, only the parts to nest. Then click the sheets after starting the nesting tool.
Never mind about the file.. mystery solved

Yikes - yes I did. Sorry for the confusion!

Re: New nesting tool ...
Wow that tool picked my curiosity. After seeing the few screenshots at the website, I DLed the Trial CAM version to give it a go. And to tell you, It kinda worked for really simple tasks but failed at a somewhat more complex task -- still simple for a human to do, that is.
Please can you give the attached DXF a spin ? I did manually nested the green example. I would expect the Nesting tool to do something similar.
Thanks for your feedback and for your work, as always

Re: New nesting tool ...
Yes, I can see that that will probably not work.
Please understand that a nesting tool is not a puzzle-solver. It proceeds more or less at random (insertion orders based on size with random variations, random angles, best position according to alignment), improving always the best fit to increase the odds to find an even better fit. Especially in cases like this one, where only a very narrow combination of angles and positions lead to a fit and the possible positions and angles depend on pieces not even inserted yet, the nesting tool is unlikely to find the best solution.
Our website shows some examples where a nesting tool can be useful (mainly for many parts that are significantly smaller than the sheet).

Re: New nesting tool ...
I understand what you mean, thanks. This explains why it is hard to do, even for some softwares we use at work.
Thanks for your reply
Oh also, you mentioned "Deepnest" in an above post. Can you shed light on it, please ?
