RHINO MAC - Issue with Layout and Detail Layer Settings in Viewport

I’ve been working more heavily on the Mac side recently and have run into some quirks with Layout and Detail Layer settings as applied to viewports. On Windows, there was never the ability to apply Layout and Detail Layer settings to a modeling viewport, but I found on the Mac side that I was able to apply Layout and Detail layer settings, which was actually pretty helpful for controlling viewports without affecting the overall layer states.

Then I ran into an issue where I opened the file on Rhino for Windows and geometry was then missing from the model viewport even though the layer was turned on in the model layers. I had no way in Windows to make this geometry visible again in the modeling viewports, but it was all still there in the layouts. Instead, I had to open again on the Mac side, made sure the Layout and Detail Layer settings for the model viewport showed everything, save, and then everything was good in Windows.

Crisis averted for a bit, until Rhino for Mac 7.4 came out recently. It now appears that the Layout and Detail Layer settings can no longer be applied to modeling viewports. This makes it consistent with Windows, but now I have geometry saved in the file that I can not see in any of my modeling viewports and have no way of turning this geometry back on. HELP!

Hi Scott,
I am testing this now.
It was probably a bug, that got fixed to your dismay.
It may need to be relogged as a “Feature Request” for a future Rhino, but I actually think it is already on the Tracker.

Until I sort it out, you can return to Rhino 7 sr3 on the Mac.
Install it and “Keep Both”.
Use “File Finder” to start the older one.

Thanks Mary.

Hi Scott -
I’ve tried to reproduce the issue here by creating a file in Rhino 6 with a parent layer turned off for a detail while a child layer for that detail was on. I didn’t have issues opening that file in Rhino 7.
I’m sure that I’m overlooking some step or setting… Could you run me through the procedure step-by-step?

Hi Wim,

It’s not a parent-child relationship if I’m understanding your described scenario. The issue is related to the fact that for awhile Rhino for Mac was allowing for control of layer appearance in the Model Viewport in the same way that layer appearance can be controlled within a Detail.

Rhino Mac 7.4 seemed to correct this so that the Model Viewport layer appearance was consistent with Rhino for Windows and could only be controlled with the Model Layers. That fix made it so some of my geometry was no longer visible with Model viewports.

I’m finding the issue hard to explain but it’d be straightforward to demonstrate if you’re interested.

Hi Scott,
Sorry for the delay.

I isolated the bug was between 7.0 and 7 sr3.
I created a request for an advanced command that would return this behavior.

It looks like when the panels were redo for Rhino 7, it was inadvertently allowed to modify the model viewports layer visibility (not color.). I know this is on the wish list, But it was going to be discuss in a feature overhaul at a later date.

I am hoping that the developer may be able to provide in intermediate solution, since it has become part of your work flow.

Feel free to add any additional comments to the YT.
I have example files and images in the YT that are not available for public viewing.

Thanks, Soctt.

Hi Scott -
It doesn’t necessarily sound like a good idea to stick to 7.3 until that time (if?) RH-63660 gets implemented. The good thing on Mac is that you can have several versions “installed” at the same time. If, after having unpacked the dmg file, you drag the Rhino 7 icon onto the desktop instead of to the applications folder and then rename “Rhino 7” to “Rhino 7.3”, you will be able to quickly “resurrect” a file that no longer shows specific layers in the model viewports.
Apart from that, importing the file into a new file will show all layers in all viewports.
