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.

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.

A machinist's model of a twin cylinder steam engine designed by Joseph Bernays in the 1870's. The original was displayed in Paris at the Universal Exposition of 1878.

Another in my series of machinist's models. This engine is powered by water, not steam. Water goes into the opening visible near the bottom of the engine and out on the far end. I believe the copper colored cylinder is just filled with air which gets compressed by the water and provides some pressure for exhausting the water.

For a scale reference, the flywheel on this model has a diameter of 159 mm.

Here's a grab of the illustration of the original full-size engine showing the valve arrangement

@nickchun you might try updating to the latest version of the Sketchucation ExtensionStore tool. The latest version is 4.4.1

Another two cylinder engine just for the fun of it.

Until such time as someone figures out and writes an extension to do that you can do it natively. I imported your first two images as images into SketchUp. Then select a random color from the native Colors collection and added it to the model. Under the Edit tab I selected the eyedropper to sample a color, named it, and then clicked on the Create New Material button.

Rinse and repeat for the rest of the colors.

What are you looking for in the Tools menu? Note what it says in Usage.

@mtanure1234 you can use the native Materials tools.

@fransko what stl file? If you are referring to the one for the clips I showed in my first post, no, I don't give away my model files. Sorry.

A model done while waiting on dinner to cook. A pulley on a hook. This is based on dimensions in another edition of the technical drawing books from Spain.

@Rich-O-Brien thank you. At least this time I didn't go overboard with screw threads. I still need to add some studs and hex nuts.

I'd love to be able to make illustrations with the feel of those old lithographs.

@Christian_33 what version of SketchUp are you using? Can you show an image of the sort of thing you are trying to create?

My first thought is to use Curviloft with a centerline and the shapes at the ends for profiles. Might be other options, too.

With Curviloft.

@Lozza944 did you do what the message tells you to do?

@a4jp-com Nope. I think this is a one of a kind.

@a4jp-com said in MSPhysics 1.0.3 (16 October 2017):

Will this work with SketchUp 2024?

No. If you read this thread you'll see the last version it worked with is 2017.
