A compound steam engine directs the exhaust steam from the first cylinder (smallest one) into the next cylinder which is larger. In the case of a triple expansion engine, a third cylinder (largest of the three) gets the steam from the second cylinder. This works because the steam still has energy to expand after the first and second cylinders. It does require the cylinders get progressively larger.

Thanks. No scavenger system for the exhaust. It's just dumped out into the room. On the other hand it's only compressed air going in.

Here's a little boxer engine intended to run on compressed air. For reference, the large gear is about 50mm dia.

Like usual I haven't added screws

Thank you all.

The only problem I am having now is that when I rotate the object (actually the camera)

So you mean orbit the camera?

the image on the back side of the heart comes and goes

Sounds like Z-fighing. Make the image of the heart a texture and apply it to just the back face of the heart. Turn on Hidden Geometry so you can paint the back separately from the rest.

You appear to have Back Edges turned on. K is the default keyboard short. Tap it and the Back Edges should turn off.

Are you rotating the object or orbiting the camera?

I do have an F1 key but I am having some new problems.

What problems? F1 is a hard coded shortcut so you can change that one.

Merry Christmas to you and yours, Rich.

Amazing!

@ntxdave said in TIG Weld Shortcut Setting:

I will try @Rich-O-Brien’s approach as well.

It's not a different approach. I just demonstrated what Rich wrote.

You're starting to worry me Dave.

@ntxdave said in TIG Weld Shortcut Setting:

I thought the Help file said you can these two keys.

You can use Ctrl and Alt for some keyboard shortcuts. Also Shift. But you can't assign keyboard shortcuts that are assigned by the operating system. Ctrl+A, Ctrl+C, Ctrl+V, for example are hard coded so you cannot assign them to other things in SketchUp.

Sure. I use W for it.

@ntxdave said in Create new or adjust materials:

I need to "smooth" or erase some lines on the heart.

Remove the internal faces between the two flat surfaces. Then you should be able to soften the edges on the surface. Those internal faces will have to go if this is a thing you plan to 3D print, anyway.

@ntxdave said in Create new or adjust materials:

I use the 3D Text editor to create the text. Is this the best way or is there another/better way to place text and an image to the face of the heart?

There's nothing wrong with using the Editable 3D Text extension to create the 3D text although you could also use the native 3D Text tool here, too.. The only benefit to using the extension would be if you want to edit the text after creating it.

What kind of image are you thinking of adding? How are you planning to add it?

I often work with a scale of 1000x. I can treat millmeters as meters that way.

@ntxdave said in Create new or adjust materials:

Would like to be able to set the RGB colors.

You can set the RGB color values if you just change the color picker.

Thank you for whatever you did. It works as expected now.

@Gábor I did send a PM.

Maybe I'm missing something but I don't see the Update All option from earlier versions. Was it removed?

If you turn off the tags for the parts you don't want and set up a scene to show the object(s) you're interested in, you should be able to export the view. Or use LayOut. It would be better for setting up the view and getting the desired export.

FWIW, Fredo has acknowledged that FredoCorner is not an exact replacement for Round Corner although they generally do the same sort of things. There are some cases in which one works and the other doesn't. I've found it imprtant to have both extensions.

@alexpacio2013 what extensions would you not want to update when the author has made updates?
