Hi Andrew,

Does this help you at all? Specifically "No binding code is needed because it is done dynamically using the Qt meta object system"

https://doc.qt.io/qt-6/qjsengine.html#q ... ntegration

I'd like to think that constraint-based CAD is easier and that it's the inevitability in this space, but agreed that it would be a pile of work.

Existing users might not know what they're missing and there's probably no good way to determine how many *more* users you might be able to attract with parametric features but I totally understand your position. I'll ask again in 12 years!

Saw this question asked in 2010 but thought it might be valuable to ask again. I've been using another cad app for my 3D printing designs and I've become quite fond of parametric constraints. Coming back to QCAD has me missing that capability quite a bit.

That's interesting. Isn't that just for leads, which I have disabled?

Well.. it almost worked. It's generating some strange tool paths that go way outside of the polyline.

That looks like it'll work. Thanks!

As the subject implies I'd like to mill out the area described by a polyline but I've not seen any (easy) way to do it. I've tried to create a series of concentric polylines, each one smaller by the diameter of the tool but selecting them an adding them to the tool path seems to confuse QCad. My gue...

Can you confirm that: - this.arcSweep - this.arcRadius aren't known at prototype post level ...? Not sure I know what you mean by post level, but I'll try to answer anyway. this.arcSweep, etc.. are set in writeEntity itself so they are not available in the override. That fact also makes it impossib...

That wasn't quite right but that link gave me what I needed.. this.nRadius = undefined; this.registerVariable("nRadius", "NRADIUS", true, "R", "DEFAULT", "DEFAULT"); this.firstArcCWMove = "[N] G2 [X] [Y] [NRADIUS] [F]"; this.arcCWMove = "[N] G2 [X] [Y] [NRADIUS] [F]"; this.firstArcCCWMove = "[N] G3 ...

Short story: I've changed my post processor to generate XYR instead of XYIJ and that works fine most of the time. When the arcs are greater than 180 degrees, the convention is to specify a negative radius. See "R Method Example 2" http://www.manufacturinget.org/2011/12/cnc-g-code-g02-and-g03/ Is the...

@Andrew Can I turn this into a feature request? How about a modifier key + mouse drag for 3D pan/zoom?

What can AppPrefs .. Graphics View .. Navigation do for you?

Not much. Those don't seem to affect the 3D window.

Follow the USB cable to the external Mouse ....

Ohh it's that thing with the ball underneath it!

Great, thanks.. but can you help me find the middle mouse button?
