Since upgrading to Rhino7 some of my macro’s creates with blocks with uuid’s behind them.  
The situation is very simple, certain blocks I use quite a lot. So i created a macro for it:

\_NoEcho  
\_-Layer \_C 0 \_Enter  
\_-Insert  
F=Y  
L=L  
A=A  
“T:\Shared drives\Library DS\3D library\D\_Kantenband.3dm”  
\_B \_Pause 1  
\_Echo

Maybe it can be cleaner but it works. It inserts the file as a linked block, scale 1, rotation I can choose, then puts the Echo back on.

First time inserting the blocks name is just D\_Kantenband (Dutch word for Edge banding), but if i then use the macro again Rhino generates a UUID behind it e.g. D\_kantenband 33902969-a431-4feb-bed9-bbf426a6ce3f. The block is still linked and works without any problems, but the name is messed up. (I also need to export the block names so then I need to manually fix the name later)

Its not just this file or macro, any block that I reimport that’s already in my file get the UUID (I re-import them because its faster than scrolling trough the insert block list, sometimes my file has 400+ different blocks).

Does anyone know how to prevent this? Is this deliberate thing that Rhino does or is it a bug?

Thanks,

Martijn

Hi Martjin - I see this, thanks.I’ll get it on the bug list. In the meantime, I would insert the block from the existing definitions after it has been inserted once, rather than go out to the file each time. My guess is the process initially needs to differentiate between the existing definition and the incoming, identical one.

Hi @pascal,

Just to let you know, this bug is also in rhino8. Would still be very nice if there was a fix for this.

Thanks,

Martijn

Hi @dale

Since Pascal is retired, I was hoping you could help me with this (also because your assigned in the YouTrack)

Are you able to pick this up any time in the next few releases 🥺?

I’m hoping this is a quick fix behind the screen, but for me this saves me huge amount of time removing al the uuid’s every time.

My apologies for “bumping” this topic for a seccond time, but I would just really like this have this fixed.

Thanks,  
Martijn
