Re: Assembly 4 workbench--Arandela Mechanism

Since it seems everyone else in the CAD world has one of these models, I thought we should have one too for FreeCAD. Dimensions for this model were taken from this tutorial: https://www.youtube.com/watch?v=98A_8qSqxh8. The model was built using the V0.19 PartDesign workbench and assembled /animated ...

Re: V0.19: Just for fun--Newton's Cradle

Thank you all for the kind comments. Would it be possible to create a very simplified assembly using these principles, and explaining the thought process in the creation, either with text or with a voice-over? What does what and its purpose... I refer you to one of zolko's excellent tutorials: https...

V0.19: Just for fun--Newton's Cradle

If they can do it in Solidworks we can do it in FreeCAD!...https://www.youtube.com/watch?v=d7QLdHGKtOk I thought it would be fun to see if I could simulate Newton's cradle motion with the Assembly4 (V0.9.3) animator. The following screenshots describe the process: Capture.JPG Capture2.JPG newtons_cr...

Re: Fridge Handle

The handle has a bunch of random curves and angles everywhere so I spent a lot of time zooming 1:1 and putting a reference handle to the screen to do shape matching. Thank you for all the interesting details. A couple of minor comments on your work process: Sometimes you can take a picture of the f...

...(only)! took me the whole day to make it!
Wow. For a complete beginner that is quite impressive. Thanks for sharing.

I for one would like to know what workbench you used, the version number, hurdles overcome, and any particular
modelling strategy, etc.

Re: Sketch or datum plane alignment to tilted face

My question is how to properly attach sketch or datum plane so it is parallel to a tilted face? Attach to the sketch that created the tilted face. Use Sketcher > Map mode > Normal to Edge and with Attachment offset rotate the sketch 90 deg about the sketch X or Y axis. This is usually fool proof un...

Re: Part design and design intent/concept

Mostly everything is already there, FreeCAD needs polish, not new features. +1 As a mechanical design engineer I prefer the Part Design workbench and Assembly4 with a few tools from Part (mirror) and Draft (arrays) workbenches. However, Part Design Fillet, Chamfer, Draft, and Thickness could use so...

Re: Datum planes, LCS, and base sketches...modeling challenge

I modeled this up using a base sketch Nicely done. It is a tricky object to model. I like your idea of using a master or "base" sketch since it has the potential to dramatically improve the robustness of the model. The real test for a model is how easily it can be changed without blowing up. For so...

Re: How do I make a Master Sketch

a reference to any documentation or tutorials about what a Master Sketch is, or how to construct one. If such material exists, could someone kindly direct me to it.

Re: How to rotate multiple bodies until they touch the edge of a third

I attempted to use the macro and got the following syntax error: I am not a programmer so hopefully someone else can help out with the syntax error. In the meantime, try this one: __Name__ = 'Measure Circle' __Comment__ = 'Compute the radius of a circle by 3 points or a circular edge' __Author__ = ...
