Parametric planter box

I've been making some finger joint boxes recently but have gotten very frustrated with needing to change the design for every different material thickness, etc. So I figured id give parametric design a shot. My first attempt was using the 2d tools in openSCAD but that was way overkill and I still needed to convert from DXF to SVG to cam it. Being a developer I used JavaScript instead, and made up this little GUI if anyone wants to make their own. It saves svg files out of the browser.

How do other people deal with having to change their designs when the actual material dimensions change? Naive question, I know.

I use a drawing program (FreeHand) which makes changes such as that pretty straight-forward.

There are some CAD tools which are described as being parametric listed on the wiki though.

I use a program called ProgeCAD. It is a paid for program but I bought it a few years ago. I do cad at work every day so I have no trouble with it. It is almost the same as Autocad. Changes are part of the life of an engineer. We just have to get used to it. Guess I did.

I've been using OpenSCAD for parametric 3D printed things, I was really surprised at how shallow the learning curve was. For CNC projects I haven't had as much success. Basically its difficult to flatten a multi layer 3D object into a single DXF (i.e. cutting a border and adding some pockets, or cutting a border and some rabbit/dado joints).

Have you tried Skeinforge for slicing OpenSCAD objects for milling? I think it works well for 2.5D stuff. It's not "proper" CAM, so it's not as flexible, but it looks like it can do basic stuff. (I've never used it myself, but I came across this use a while ago.)
