A hook on a pulley for some sort of crane or something. Based on dimensions given in an old, undated book from Spain of technical drawing exercises.

This is a heel strap for a wheelchair to prevent the user's feet from sliding off the foot plate. It's designed to install easily with no tools required except scissors to trim the strap to length. The clips with snap on covers are 3D printed to fit off the shelf polyurethane toothed belting.

From the SketchUp model.

Partially assembled.

Temporarily installed on a chair. Ignore the dog hair.

Combined a Vray render with an AO export direct from SU24.

Experimenting with creating a vintage illustration style for my SketchUp models. The flywheel is based on dimensioned drawings in a textbook from 1897.

This one is called Lady Stephanie. I don't know who the real Lady Stephanie was but if she was anything like this engine, I'm guessing she was kind of ornery and hard to please.

After putting her aside I did another engine today. This is a a little crankless engine.

From an old book. SketchUp and Paint DotNet.

A model of what is probably the first micrometer ever made. It's dated England about 1776 and attributed to James Watt although evidence shows it likely wasn't made by him.

A larger version of this image is available here.

All the screws are made and holes threaded. 28 component definitions, all solids.

Funny guys!

And here's another one. A little 4-cylinder oscillating engine. As usual, all base level components are solids.

This is from a model I initially made 11 years ago for shop drawings. I pulled it out recently to do a bit of refining in SU2025.

@MLUY you could select all the geometry and do the same thing. You'll only soften edges in which the angle between face normals is less than or equal to the angle set in the Soften Edges panel.

Select all of the edges that you want to soften, right click on the selection, choose Soften. If needed, adjust the slider in the Soften Edges panel in the tray.

Thank you. The glass is part of the cylyinder. It gets heated with a flame underneath. The piston is the metal round-ended bit inside.

@alskaro do you mean something like this? As TIG says, apply whatever materials you want to the various faces in the SectionCut Face.

@Rich-O-Brien thankee kindly, sir.

@ntxdave thank you.

Machinist's models.

Can't you just select it to highlight it and hit Delete to make it go away?

Are you modeling internal or external threads?

@Leggy said in help with a thread:

What about tpi?

What do you mean? The thread pitch is given along with the other dimensions for the threads. TPI standas for Threads Per Inch and is not used for metric threads. M22x2.5 indicates the nominal diamter is 22mm and the pitch is 2.5mm. The helix rises 2.5mm for each rotation.
