Hello,

Sorry to answer a bit late.
Regarding the groups, there are a few things to know about them:

when a group is not locked (icon on the left hand side of the group name), it means that if you click on a part of this group in the scene, you will only select the one part. If the group is locked, you will select all the parts included in this group.

If you create a new group with parts belonging to another group, the parts will be removed from the old group to be put in the new one. It is probably how you ended up with empty groups.

For instance, you shall first lock the group of the steering wheel and only after create the parent group that will include it plus other parts.

When I build on mecabricks, I lock my groups as soon as I can to avoid bad surprises later.

Hope I did not make it more blurry than before 😉

It is not possible to open the "group tree" under a group when the group is locked. Could you make it possible? I think many users miss the possibility (like me) to see what is contained in a group when it is locked.

Hello,

The group system was quite complex to code and I had to do a few concessions.
The idea was that a locked group cannot be modified and therefore to avoid a long list of cases to handle I simply made them non-openable.
You can just click on the lock if you want to see the content and then re-lock it when you have finished... It just adds wo more click 😛

is it possible to name the groups?

Hello. Yes, double click on the group name to open a popup.

Have run into a few issues working with Groups in Chrome on Mac (haven't tried Safari yet):

• Is it possible to delete an empty Group?
• Should the groups display their contents?

Yes, you can delete an empty group. Just click the group and press delete. And I don't think it's necessary to display the contents, because all you need to do is click the group and everything that belongs to it lights up. You then could drag it to the side if you want a better view of it. 😃

Thank you... I was trying to use the little minus in the group block before I realized those (the plus/minus) articulate parts in/out of the group. Quickly ramping up the Meca learning curve here.

How do you put groups into groups? I've tried, but with no success.

Select group(s) and press J to put in new group or click the option button of the new parent group and select "Add".

how do i make a group

@earland003, Select the parts you want to group and then press J key or click on the group icon in the left hand toolbar.

How do I put pieces into a group I have made? Thanks in advance for the reply!

Click on the gear wheel of the group, choose Add.

Thanks! I figured it out.

(sorry for bad english) how i can set a part parent ???

and how i can make for example a weapon and a upper part move together ?

i discovered it myself, ignore my quest
