bmBrowser no longer available to BricsCAD Mechanical customers?

This means that you have Platinum V19? As far as I can see, you should then have the Mechanical Browser if you right-click on the menu bar. It is also a command called MECHANICALBROWSEROPEN. it is also a command called MECHANICALBROWSERCLOSE
.

I guess that some of what you are looking for might be in BricsCAD V19 Mechanical. In V18 you had Platinum + Sheet Metal, but in V19 you don't have Sheet Metal but a Mechanical edition that includes the Sheet Metal tool sets.

Suggest you get in touch with your Bricsys/BricsCAD representative to discuss.

If you have V19 Platinum, Mechanical, and Communicator, you should have all what you need. It must be something else not working. I had some problems since I have been testing what is available on lower levels, Classic and Pro, and Platinum and Mechanical didn't reset for me.

I then went to Settings, and searched RUNASLEVEL and made sure that it all was set to run with all the active licenses I have. You should have Platinum, Mechanical and Communicator activated in the settings. See the screenshots of how my settings are now.

Another thing, If you have customized a button in the Assembly toolbar to run the "bmBrowser" command. That command is not valid anymore and the command for the button should be changed to MECHANICALBROWSEROPEN. But if you also want to open the Components library, that command is COMPONENTSPANELOPEN.

It is not called bmBrowser anymore. It is Mechanical Browser - MECHANICALBROWSEROPEN and Components - COMPONENTSPANELOPEN.

I suppose the reason can be the old CUI file. After every new installation and the first program start you usually have to see the message about the update of .cui file.
Try to click by right mouse button on any toolbar/ribbon and choose Customize. In the customization dialog use left bottom button (manage your customizations... ) Then use "revert to default" on the bottom part of the dialog.

ATTENTION: this will revert all your GUI customization to default!

I'm not going back to the default CUI until someone explains in detail how to use the partial for customizations.

A partial CUI file, when you create one,
by default just exists in the same folder beside the default.cui.
It is basically the same as the default CUI - but empty, when you start.

In Customization Dialog, once loaded, the partial CUI will also exist beside
the "default" Bricscad CUI in any customization Tab.
Like on the right side all available Tools/Options, on the left side the default
Tools, inside a Bricscad "default" Group/Folder
and below will be your Partial Group/Folder.

There you will duplicate, create or modify things like Tool Palettes.
E.g. a custom Tool Palette similar to a default Palette, but without any Tools
you don't need but maybe other Tools you want to be there.

So when you created all things you need in your partial CUI file by saving
the Customization Dialog and go back to your UI.
When opening Toolboxes, you will now have access to both,
Bricscad Toolboxes (Default.cui) and YourCustomTools (partial.cui) Toolboxes.

Like when you created a better version of the Manipulation Toolbox,
you would close the Bricscad Manipulation Box and instead open your
"Manipulation Box"

The default CUI has a risk of being overwritten by installations or updates,
opposite to the Partial CUI file will stay.
As so far you did with the Default CUI, you can transfer the partial CUI file
to other machines or new versions of Bricscad and load it there.

There are some general risks in Bricscad's UI Customization.
Like Tools saved in any kind of UI files may no more be available or replaced
in future versions of Bricscad, or new options added that you will not see
when overwriting by your "old" files.

Also I had issues when duplicating existing Palettes before customizing,
using the same names and such issues. Forcing Palettes to open automatically
or where they will dock may have been also risky.
But maybe those were just issues with previous Mac Versions of Bricscad.

Also there is now the concept of the "Workspaces",
but I don't really get how these will work together with partial CUIs or where
they replace it ....

As to yr last para - I use Workspaces bigtime but also don't understand how to set things up incl them, and CUIs, and Profiles ...

The difficulties with CUI's/workspaces keeps coming up with regularity. Myself I couldn't get my head around it, so thanks to someone on this forum they recommended using Profiles which works for me but I use a pretty simple setup.

I don't have room on my screen for more toolbars.

That is why I use a partial CUI.
I create some some Panels similar to the existing Bricscad Panels,
but just the Tools I really need, without the extra stuff.
So I close Bricscads View Panel and activate mine instead.
That avoids screen waste.

The toolbars I have activated for each of these workspaces are different. Is that saved in the customization, or the user profile?

That is where my knowledge and experience ends ..
I think,
which Toolbars are active and which hidden is normally saved in your Workspace.
But as far as I know you can force Toolbars in Customization Dialog to automatically
open. But maybe that is overwritten when you manually close such Panels any way (?)

Far too complicated for me.
Other Apps offer a Tabbed UI for me (like Modo or Blender)
Where each Tab for a specific Workflow holds the collection of Tools needed.
Or save just my customization of the Default UI, without offering both beside
each other

When you start with your attached partial UI it is empty.
Theoretically you could copy over all things the default CUI offers
in Customization and start modifying these.
(Or duplicate the whole default CUI file ?)

As I said I had problems with duplicating Palettes in the past on Mac,
that may have been fixed already. But I'm still not confident to do so,
so I personally do them usually from scratch.

You should look at Ralph Grabowsky's eBooks.
There is also an option to use your Partial UI as the Default UI and
the Default as Partial UI. Forgot what the advantages were.

I am the wrong spokesperson for what is possible or what may forbidden
or risky as the whole system is too complicated for me.
When I started with Bricscad I had to delete my whole Config and edited
Default CUI and start from scratch every 2 weeks for over a year.
So far I just use the minimal part of options that I really need and where
I did not experience lots of issues.

You can do so,
it is just the risk of being overwritten, when you update
before you back upped .... which happened for me
a few times.
