Re: V0.19 Top Down Assembly Design Using Assembly4--Update #5 Steampunk Lighter

This is the 5th example from the original post that demonstrates use of PartDesign master sketches and Assembly4 during top-down design of a steampunk cigarette lighter found in a restoration video on YouTube. Comments about the work process are included in the captions of the following screen shots...

renaming the property from "m" to "module" works for me
OK, thanks for verifying and the quick fix.

Please test if using an expression for the module-property works now.
Works just fine for me as well.

Great workbench!

Re: Gears in FreeCAD: FC Gear

...ping Here is some odd behavior with a bevel gear object in the Gear workbench, perhaps it is a bug that hopefully can be fixed. If one tries to add an expression to the 'm' (module) parameter in the gear property panel and then save the file, when the saved file is retrieved, the expression is m...

Re: Simple shapebinder / sketch / face referencing question

if I wish to reference a sketch (or maybe some additive / subtractive geometry) to a solid face, I should build a shapebinder on the desired face and use that, correct? IMHO yes. That is , a shapebinder of the sketch but not attached to a face, only the origin planes. Either that or a Sketcher > Ca...

Re: Suggestions for improving my part design workflow requested

The fundamental question is: how to reference specific geometry from other sketches rather than solids? You can use a shapebinder of the sketch with external reference or more directly, a carbon copy of the sketch. Convert the carbon copy to construction lines (blue) and then add/subtract and const...

Re: V0.19 Top Down Assembly Design Using Assembly4--Update #4--Geared Hand Grinder

This is the 4th example chosen to demonstrate the advantages of the master sketch approach and the Assembly4 workbench for top down design. This is a geared hand grinder design loosely based on one found in a restoration video on YouTube. Model_2_master.JPG Model_4_pinion.JPG Model_5_mesh.JPG Model_...

Re: V0.19 Top Down Assembly Design Using Assembly4--Update #3 Antique Blowtorch

A few of you are still hanging in there (435 views last count of the arbor press details) so I will continue with some of the details of the work process for the third project, the antique blowtorch: Picture2_exploded.jpg Picture3_master.jpg blowtorch4.gif blowtorch2_tubing.gif Picture4_modified.jpg...

Re: V0.19 Top Down Assembly Design Using Assembly4--Update #2

I just made a silly bare-bones example showing my modeling workflow. Not so silly. Thank you for sharing your file and workflow. I learned so much studying your tree, step-by-step: 1. How to get the master sketch into ASM4 Model by simply assembling it. Avoids the out-of-scope warning I usually get...

Re: V0.19 Top Down Assembly Design Using Assembly4--Update #2

There is another way, namely start from the master sketch and attach the bodies' sub-sketches to master sketches using LCS:s. I have linked sketches together using LCS's for 3D movement but not sure if that is what you are suggesting. I would love to see an example. Perhaps you can post one with so...
