Parametric modeling in SU, like in Fusion 360

Thanks, Samuel, interesting plugin!

You should use “Number” nodes to set simple dimensions. “Calculate” nodes are designed to evaluate complex formulas.

A documentation is available at GitHub.

Looked at that already, but I see now the use of Number, not Calculate. Thanks for your prompt response.

I think it needs recourse to another Shape, and even that won’t be straightforward

I made my first schema!

SketchUp? CAD Package???

I just spotted this on another forum. Despite Trimble’s best efforts , they just can’t seem to shake off us Bohemians - 3d printers, Artists, CNCers. In fact, they are growing like crazy if this chart is anything to go by.

[MikeWayzovski]

SketchUp has always been the ‘un CAD’ amongst other packages, it is part of SketchUp founders philosophy.

Here’s a link to that site:

CNCCookbook 2021 CAD Survey [ Market Share, Customer Satisfaction ]

Note the ‘pirated section’, Google seems to have done a great job there.

They only call us pirates because we aarrrr.

Cross fertilizing the threads, I propose another 60 second challenge.

Build any internal and external screw thread in hex, hex socket, cheese, csk head from, say, M4 to M12 in less than sixty seconds. Plugins and prep time allowed.

Apart from staring blankly at an array of icons, I’m wondering if SamuelT hasn’t come up with the holy grail for those of us endlessly winding triangles round spirals. Please tell me it’s possible. I’ve just spent two hours threading my 3d printed plastic T-Nuts for my manual mill.

you forgot the 3d Warehouse?

Not entirely, Mike. I don’t want to seem churlish but I’ve tried the 3d Warehouse for bolts and screws and reverted to the DIY option. I appreciate it is a beta release at present, but if this plugin is what I hope it is, I’d call it phenomenal.

[robinmorritt]

Not one to spurn friendly advice, I installed FreeCAD, downloaded a McMaster-Carr STEP file, converted it to STL, loaded it into SketchUp for inspection, then fed it to Cura and spat out a replica on my 3d printer and now offer three observations.

1. It all worked perfectly.
2. Microsoft Weirdows is irritating.
3. The geometry in the other pics is basically why I avoid incorporating foreigners in my models - 36, 40 and 42 segment circles, 216 stray edges and 127 holes in the mesh (which Cura is perfectly happy about ).

So, yes, it’s an amazingly trouble free result, but I wouldn’t fancy putting dozens of them in an assembly or tinkering around with them for 3d printing.

Interesting exercise. I definitely learned something there. Thanks.

Love the Plugin Samuel thanks! Its my first node experience. Question: how can i benefit from the calculate node? can you give a quick example of how to use it?

[SamuelTS]

@mcheru “Calculate” node has its Wiki page. If you want a live example: Open Nodes Editor. Right click in void to display context menu… Click on “Import schema from a file”. Select “Door.schema”. Study how variables are used in “Formula” field of “Calculate” nodes

[mcheru]

Thanks!!!
