@alexpacio2013 said in Discussion - object is not a manifold solid !?:

I guarantee you that Bool tools 2 works and works better than the standard tools even among solids

You're preaching to the choir on that point. I don't use nor even recommend the native Solid Tools.

I guess I have no problem, even for complex objects, with making them solids so I get predictable results when using Bool Tools 2 or Eneroth Solid Tools.

Thank you all.

For those who aren't familiar with reading micrometers, the lead screw which drives the moving anvil has 20 threads per inch. So one full turn of the screw moves the anvil 0.05 in. That moves the pointer on the small dial one division and of course the pointer on the large dial, a full revolution. The major divisions on the large dial indicate 0.001 in. I don't know how precisely the original lead screw's threads were made but a device like this can be quite precise in its measurements.

Close Sketchup. Go to user/AppData/Local/SketchUp/SketchUp 2025/SketchUp and open PrivatePreferences.json. Look for "ThreeDTextDlg". What are the "x" and "y" values? Edit those to move the dialog onto the correct screen. This is what it looks like on my computer.

And here's the dialog relative to the top left corner.

Note that the user/AppData folder is normally hidden so you'll need to make hidden folders visible in File Explorer.

Did you install SketchUp 2025 correctly? That requires right clicking on the downloaded installer and selecting Run as administrator. If you didn't do that it's possible that Windows is preventing SketchUp from making suitable updates to PrivatePreferences.json. To ensure SketchUp is installed correctly, close SketchUp, find the installer in your Downloads folder, right click on it, choose Run as administrator, and when prompted, click Repair. No matter what, it won't hurt to do it.

No need for a plugin. Just select all of the geometry, right click on it, choose Intersect Faces>With Selection and then erase the part you want to keep.

What do you need from these threads? Do you just need to represent threads are are you planning to 3D print them? Or maybe something else?

If I need threads that match existing standards, I find it better to draw the correct profile and extrude it along a helical path. Here are some fairly recent examples.

@HornOxx thank you! Two ceparate lines-only exports from SketchUp combined with the render from Vray.

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

I see a major issue is that your profile is offset inward from the path but more than the radius of the arcs at the ends.

Do you really want the "knobs" at the ends to have that corner.

Here the profile (shown selected) is aligned with the path. On the right you can see some of the resulting extrusion. Might be better to put the profile outside the path.

@panixia that's fine. I was simply demonstrating what it would take for the OP to use the texture image they shared.

@Rich-O-Brien
Not a whole lot of difference with AO on this one.

@Gili It works perfectly in SketchUp 2025 and 2026. I've been using it a great deal. I used it repeatedly the other day to set up the linkages on this paddle wheel.

The only legit license for SketchUp is a subscription and has been for a few years. To activate SketchUp you would enter the email address and password you used when you purchased the subscription. You should be able to do that for two activations. That could be on two different machines or two different versions of SketchUp on the same machine.

Presuming you've installed SketchUp 2025 on your PC, what happens when you start it and enter your email address and password?

There isn't a free version of SketchUp for desktop and hasn't been since 2018. There's a 7-day trial but you shouldn't need to use that. Just enter your subscription credentials.

To illustrate what @Rich-O-Brien described, I made a 3D model in SketchUp based on your image.

I imported your image into SketchUp as an image to trace. I made it quite large--200m tall--to avoid the tiny face issue. I used a combination of straight edges and Bezier splines drawn with FredoSpline to outline the letter, draw in the ridge lines and connect them at the various ends. Then I used TIG's Extrude Edges by Rails to create the sloped surfaces. Bybreaking it into a few sections, Extrude Edges is more controllable.

The blue edges show where I divided things up.

@HornOxx from where did you delete them? On Windows the shipped materials are in Program Data.

I think Rich is correct that they are also hard coded so they would get rewritten if you delete them. And certainly the folders would be rewritten if you reinstall SketchUp.

Another little machinist's model. The flywheel on this one is 35mm diameter.

@Loikkanen123 using inferencing as Rich and Box show makes it easy. You need to be grabbing the object by a point that corresponds to the destination point on the other object.

Another thing to consider is modeling objects in the location you need them so you don't have to move them into place.

Did you look at the video on it's ExtensionStore page?
https://sketchucation.com/plugin/1103-extrudetools

I still don't have time to do a video on the entire process but maybe this will help. I copied out the needed edges from the L I already made for this. Note that the straigh edges at the ends need to be divided into multiple segments and welded to make them curves. Two segments is enough, though. Going through the options I chose to no delete the original curves. Since the entire letter gets done in stages, you can't delete all of the edges after an extrusion because you'll need them for the neighboring steps.

@Bryan-K thank you sir!

Here's some views set up in LayOut.

Output Override is a Document Setup setting so yes, you can save that as part of your template like the rest of the Document Setup options.

@Leggy said in Annoying pop up:

Don’t tell me you’ve never drawn over hidden geometry

I haven't because I don't leave loose geometry in my models. One of the first lessons I learned about using SketchUp, even before learning about Hide, is that the geometry is sticky and new geometry will merge with existing geometry.
