Update version #, I assume? Done. (And guaranteed not to remember to do it again that when 2019 comes out.)

It doesn't, by the way, appear in the list of checked/unchecked items for the tray in which it appears. So I can't just uncheck it to make it go away.

Layout 18.0.16975 64-bit.

This just appeared on my Layout toolbar today. Any idea what it is?

That did the trick, TIG. Thanks!

Looking back on this thread, I see some discussion about problems dimensioning in Layout. IE, with cut face edges hidden (as is the default), the dimensions have nothing to snap to. The proposed solution was to turn the edges on. But now this can cause problems with the new associative dimension feature, because if/when section cut faces are remade, any dimensions snapped to them "break," and stop keeping up with changes in the geometry like they're supposed to. To keep the dimensions associative, they must be snapped to the actual geometry "below" the cut face. To do this, I think, requires turning the cut faces off during dimensioning.

Sorry, Dave R, I worded that poorly. I don't right-click the context menu item. Rather, I right-click the section cut to bring up the context menu, from which I left-click the "Add SectionCut Face" item.

Thank you, TIG. The version is 6.1. I must have just missed 6.2. However, the "Update" button for Add SectionCut Face in Extension Manager is inactive. I will try uninstalling and reinstalling.

I just installed SectionCutFace. I get the context menu "Add SectionCut Face" but right-clicking it does nothing, other than closing the context menu. There is no dialog box to specify the paramenters, and no section cut face is generated.

After right-clicking, the following is added to the Ruby console:

Error: #<NameError: uninitialized constant TIG::SectionCutFace::COMPO>

Other info: I am running Pro 17.1.174 64-bit on Windows 7. The plugin was installed using the Sketchucation ExtensionStore interface.

I use this one...

That's exactly it! Thank you.

In the meantime, I also cobbled together a "Rotate 90" out of TIG's TextureTools plugin that works more or less the same way.

It will be interesting to see how long it will take me to save as much time rotating textures as I have spent on coming up with a faster way to do it!

Try this....

Thanks for that! Aside from being a helpful tool, it also shows me that it is possible to make a "rotate selected texture 90°" tool, for which I could make a shortcut. Perhaps a good project for me to learn a bit about Ruby!

@dave r said:

Generally I manage to do the rotate thing once for a model and then sample that rotated texture for the other parts where I need the same orientation.

Yeah, I learned that trick somewhere and it definitely helps. But I still find myself doing a fair amount of rotating, because when sampling, it's not obvious whether a texture that appears to be rotated is actually just the un-rotated texture, applied to a rotated component. So I can sample a texture that appears to run the direction I want, but I may or may not get it. Meaning I have to try some other sample source, or just go ahead with the three to nine (depending on how you count) steps to rotate it.

So would it be possible to rotate the texture of a selection 90 degrees with a ruby script? If so, I could assign a keyboard shortcut to that script.
