I’m having an issue in rhino when I create a block. The appearance in ghosted mode changes and darkens the same closed polysurface if it is a polysurface within a block vs a simple polysurface. It’s somewhat benign, but because it’s darker and grayed out it sort of makes the block appear locked compared to other items. Has anybody else experienced this?

The above image shows what is happening. The 1st and 3rd polysurfaces are exploded and not within a block while the 2nd a 4th are identical polysurfaces within a block.

Hi John,

Please run SystemInfo command in Rhino and post the result. A small example file is usually helpful as well. Thanks!

I believe this was fixed in 8.18, please update and try again.

Huh, strange, when did that update come out? The automatic updates on my Rhino said I was up to date even though I was only running 8.17

8

It still a release candidate

Hi John -

New Service Releases are published every second Tuesday of the month and Service Release Candidates for the next version every Tuesday.

This particular issue was fixed in 8.18 which became the current SR two days ago.

Sometimes it takes a restart or two of Rhino for it to find the update. If all else fails, you can use the link on the Updates and Statistics page to manually download and install the update.
