Shell of follow-me extrusion doesn't disappear with layer

Your Lemo Cable component is assigned Layer0. So hiding the cable layer doesn’t actually hide the component.

However inside the component most of the geometry is set to the cable layer. So they become hidden when the cable layer is hidden.

The wires are set to Layer0 so they are not hidden.

The correct fix is to select all the geometry inside the cable component, and set it to Layer0 (or untagged in 2020). Then set the Cable component to the cable layer.

I thought the center axis of screw/washer assembly was on the z axis. I’ll check when the purge finishes.

Did it take a very long time for you guys? Seems like 15 or 20 minutes so far.

Thanks again!

After a couple of hours, the purge finally returned. I then did the cleanup3.

Wow! What a difference. The performance for my needs is now adequate. Thanks to Box and DaveR for the tip to do this!

I triple clicked on the wires as Box indicated and change their layer from “blank” to layer0 (I’m on SU 2018). Then I assigned the component to cable layer. Now’s all good!

I post questions to many forums. The replies on this forum are the fastest and best by far. DaveR has been especially helpful over a long period of time, typically with a timely reply just minutes after I posted the question, even at strange hours.

Thank you!

Wow! On my computer it took 1 minute and 47 seconds. to complete the purge. It would be nice if Sketchup showed a progress bar instead of freezing things indefinitely.

Interesting.

My processor isIntel® Core™ i7-7820X CPU @ 3.60GHz, 3600 Mhz, 8 Core(s), 16 Logical Processor(s)

I have 8 GB memory, and lots of unused motherboard SSD storage (hundreds of Gigabytes.).

This was about the best available around 5 years ago. The performance I was seeing made me wonder if it was time to buy a new system. But, after the purge, performance is reasonable for everything I’m doing.

I did use Task Manager to make sure SU was actually doing something. It WAS consuming processor resource, though only around 20%, according to TM.

Memory usage was under 7 GB–I shut everything else done while it was crunching, but still it took well over an hour.

Also, before the purge, just opening the file took over a minute. After the purge (and cleanup), it only takes a few seconds.

Sketchup (and all cad) is a single thread operation, it can only take place on one core. So it’s possible for Sketchup to be locking up it’s single core with work while system diagnostic says there is still available resource.

Here are two versions of purge in real time on your file.
The longest part is in the middle when I revert back to do the second purge.

I suspect there is some tweaking that needs to be done to your system if it is taking so long.

How long did it take on that PC?

The gif in the post above is in real time. So you can see how long it took.

Wow. I can’t imagine what could be tweaked to make such a difference. I’ll go back and try it again.

First, I just want to repeat the purge where it took over an hour It’s working again now, been a couple of minutes.

One difference in what I’m doing–I have "Only components’ clicked. I’ll see if that makes a difference. Also, SU 2018.

Still running. Task manager says 9% CPU, 1.5 GB memory usage. 0 GPU, 0 Disk. Power Usage “Very High”.

Total computer usage is 13% CPU, 36% memory.

Reproducible. Still running over an hour later. I’ll kill and try with Entire model and show nested components.

That didn’t make enough difference to get the kind of performance your gif shows (still running after restarting). Could the installed extensions make a difference?

I did add one that monitors changes to the active layer and issues a warning when it’s changed. Maybe something gets triggered and has to time-out during execution of the purge command? Just a WAG.

Not a pressing issue for me, since the purged file has good performance. Besides, I wouldn’t know what/how to “tweak” or investigate further.

Thanks for trying it on your PC.
