Editing external linked block causes 100% CPU load

Rhino Rhino for Mac

It happens since years, that Rhino for Mac is going to a 100% CPU load. Sometimes these strange bugs get fixed, but as we can see in the screenshot below, it now happened again.

I already had many discussions about this problem and each time it was a big hassle to find the source of the problem. Over the years I have invested hours just for this specific bug (strange 100% CPU usage for no reason) Now I have an idea / question:

Would it be possible to have a trace command in order to quickly find what process is causing the usage, similar to the activity monitor?

Regarding the problem itself: I just opened a file with some blocks and double-clicked one of the blocks.

I have posted my system info already 100 times, but here it is:

update: the 100% CPU load is stopped as soon as the second Rhino session, that is opened due to the opened block is closed again! @dan

3

Completely easy to reproduce:

Open the testFile, where testCube is linked as a block. Then double-click the block to edit in a new file. CPU load will go to 100%.

@dan

testFile.3dm (2.4 MB)

testCube.3dm (2.4 MB)

it gets worse: clicking objects in opened linked block files does not trigger the properties panel:

Thanks for reporting this Rudi! Those easy-to-reproduce ones are the best kind. Appreciate the clarity of the report. I’ve added this to the pile to look investigate:

RH-81972 Opening Linked Block causes CPU load to go to 100%

Thanks Dan, please dont forget this one as well

Hi @rudolf.neumerkel,

I see the high CPU usage when block editing. Just curious - what problem is this causing for you?

Thanks,

– Dale

It’s making my Intel MacBook Pro very hot and kicks on the fans for no reason.

It disturbs the silence I like to work in as well.

It drains battery life.

10

It doesn’t do this in Windows Rhino…

11

The slowdown appears to be in our effort to disable the source document and any associated UI.

– Dale

12

I guess this is an easy fix?

13

@rudolf.neumerkel - I don’t know enough yet to give a good answer.

– Dale

14

When opening the external block, the properties panel also does not work, btw…

15

I didn’t forget. I’m just slow…as you already know I’m sure.

Logged here: RH-82088 Properties Panel for object does not show in linked block document

Sorry for the delay!

16

thanks, please let me know if one or both of those bugs are fixed…
