Re: csv to vcarve pro
thanks adrian. That gadget seems pretty complex no? all I would like to do is enter the dimensions of rectangles and then have them lay out in vcarve.

Re: csv to vcarve pro
Only slightly more complicated. Even if you just provided dimensions, you would still have to tell it where to place the rectangle. The gadget assumes you will do that explicitly by giving two corners of the rectangle.
So,
!Rectangle, 10,10,20,20
will give you a rectangle with one corner at x10y10 and the other corner at x20y20. That single line is all you need for the rectangle.
The whole set of csv programs deals with both 2d and 3d shapes. The 2d part is fairly straightforward. You just need the gadget called "CSV to 2d vectors"

Re: csv to vcarve pro
I downloaded that gadget years ago but never had a chance to look at it. With the posting of this thread and having had some time to play with it I can foresee getting really into using it. It's going to be especially useful when linked to Rhinoceros 3D's "Grasshopper" parametric visual programming plug-in. For more on Grasshopper you can see our own TReischl's video: https://www.youtube.com/watch?v=1y_47dHqZso
One thing to watch out for with the "CSV to 2D Vectors" part of the plug-in is how it creates circles (at least in VCarve v9.519). It would be interesting to see if v10.xxx has the same problems as below.
I used the following code:
The way "CSV to 2D Vectors" creates a circle is by creating two arcs starting from the top and then from the bottom:
But that creates a circle whose X width is not quite what it should be:
The right-hand arc is OK but the left-hand arc is slightly narrower. The centre of the circle is OK too.
As a test I altered the LUA code for the gadget to draw the circle as four arcs instead of two:
With that change the size is now as it should be:
If you want/need to make the fix yourself then change the two c:ArcTo lines from:
to:
