Re: running macros ... I must be doing something wrong

If I open a fresh copy of FreeCAD, create an empty sketch, close it and run the Macro, it appears to work. Screenshot 2024-03-18 at 4.37.52 PM.png But to be more useful, almost any recorded macro generally need some editing. For instance, this one will only work with a document called 'Unnamed'. At ...

There's no lag, then?

Re: Swash Cylinder

Here's an alternative way to make the cutting object. Instead of constructing the required ellipses to loft using their parametric equations, and the Parametric_Curve_FP macro, I construct them geometrically. Requires some trig to get the coreect cutting angle for the inner ellipse. Screenshot 2024...

I expect it is going to be a good tool.
Do I need the Ondsel branch, or is the weekly up-to-date with Assembly?

Re: Get getGlobalPlacement for a Link.

What if that Part also has parent's? I would expect that getting the GlobalPlacement would involve multiplications of all Placements from a Part at the root of a document all way down through other Parts until one gets to the targetObj and if the targetObj is a Link that Placements of the LinkedObj...

Re: Swash Cylinder

Am I right in thinking that I can just change the diameters in the DD object? Can I change the angle too in the same way? Is there some docs somewhere for DD and FP? I guess I will have to adjust things to optimise different versions of the device. So many questions, sorry. Yes in a parametric desi...

Re: Swash Cylinder

The error message says that the Parametric_Curve_FP isn't properly installed. Create a new file, go to Macro|Macros, look for Parametric_Curve_FP in the menu and execute it. You should get the default spiral. Likewise, go the dynamic data workbench and 'Create Object' in the workbench, to ensure th...

New Assembly Workbench

Are there any tutorials/videos/documentation on the new (0.22) Assembly workbench? Assembly makes no mention of it.

Re: Swash Cylinder

Mar-17-2024 17-09-34.gif You can control the parameters with the dd object. I wasn't sure how exactly you wanted the top surface, so I left that to you to suitably slice off. .You'll need the Dynamic Data WB and the Parametric_Curve_FP Macro loaded to play with the model. Here's the cutting object:

Re: Curves workbench

On similar lines, I think a points outout option for isocurves would be useful, providing vertices at the isocurve intersections. Then you could provide references at any desired u/v location on the surface.
