This is an impressive assembly, would you be willing to share a little about your modeling strategy? Part vs PartDesign, A2, A2+, A3, those sorts of decisions you had to make along the way?

Hi emills2.
This particular model I generated a little over a year ago in FC V0.16, the greater majority of the parts were drawn in Part Design WB with the use of Part WB for Helix, cubes and cylinders, all assembled using A2.
Assembly strategies vary with the model at the time, sometimes starting from the ground up or from the middle out, components drawn in numerical order as indicated on the plans.
In some conditions Sub assemblies are useful, my only hesitation in creating subassemblies is that they do not retain the correct colours when imported into an assembly, I guess it is due to the different lighting angles of each part

I am now using V0.18 with assembly A2 plus 4.25, however, I do use the overlap facility incorporated in V0.16 A2 to check placements etc.
Thanks for asking and your comments.

I have never heard of a horizontal rotating piston, and the link was not that informative. Is this a steam version fo the wankle engine? :?

Awsome model. I am always impressed when I visit the user showcase.

In a way I suppose it could be remotely related to Wankel engine, I admit I had not thought about it those terms.

Reading about the sealing issues reminded me immediately of the Wankel engine. Wankel wasn't really an engine specialist, he was a sealing specialist.

FAO. jtm2020hyo.
Hi, I would be happy to share with you.
However the file of parts including assembly is 8.47 MB and is to large to include here.
The location of the plans was included in original past.
I can post different views if that would help
Any Questions please ask, I'll help if I can.
