Eneroth Solid Tools taking a very long time to do a subtract or trim (SU 2026 on Mac)

I’m not sure which forum topic this belongs in, but since I’m talking about Eneroth’s Solid Tools, I thought I’d try the “Extensions” topic.

Eneroth Solid Tools on SketchUp 2026.1 (also 2026.0 and, I think, 2025) on my M1 Max MacBook Pro (running Sequoia 15.5) is running extremely slow doing either a trim or subtract with two intersecting curved solids. It does eventually finish the action, but is so slow the Mac is showing the spinning beach ball cursor for many minutes (3+), and the OS thinks SU is not responding (aka frozen). I did try the same trim and/or subtract using SU’s native Solid Tools, which completed the task in a second or two.

I’d honestly prefer to use Eneroth’s Solid Tools when possible since it maintains my component as the same component whereas SU’s Solid Tools converts the component being acted on into a new group. Eneroth’s Solid Tools has worked just fine in the past (SU 2024 and older)

I’ve included a sample file that shows the problem. Specifically, subtracting an Elipse ring from a central Hub assembly. The sample has both the unmodified Hub assembly component with the two cutter solids located as required, and a modified version of the component created by SU’s Solid Tools. Again, Eneroth’s Solid Tools got there without crashing, but it took a very, very long time.

There’s a lot of geometry to process so you need to give it time. You might try Bool Tools 2 instead. It’s often faster.

This is real time with Bool Tools2

Thanks Dave.

SU Solid Tools (SST for short) was near real-time-ish. Eneroth’s Solid Tools (EST for short) used to be just as fast. I’m just wondering if there’s a Mac/SketchUp/EST code problem now?

Also, thanks for the Bool Tools 2 lead. I’ll try that out as well. That said, in your screen cap vid, Bool Tools 2 did look like it took 15 or so seconds on each cutter. That’s acceptable, but SST only took a couple seconds on my Mac.

Since you are working with components I copied and scaled the objects x100.

This was real time with Trim+Keep Plugin working on my Mac:
