How to delete multiple blocks at once in Rhino8?

In Rhino 7, it was possible to delete several highlighted blocks at once:

I’m struggling to find this option now that our company has moved to Rhino 8.

Where has it gone?

More over, where are all the other important options, like “Count” and “Select”?

Hi DuncanW,

Those are available via Right Click

Thank you, but I cannot get that to work.

The point is that you want to do the selection in the model, as that’s where you see the blocks in use. I don’t want to have to repeat selecting in the Block Manager, as seems to be necessity now, as a single right-click will cause a new highlight-state that then only deletes that particular block.

This feels very clunky and inferior compared to Rhino7.

For files with a large block library of 500+ definitions, it’s impossible to select individually.

I will ask for a downgrade to Rhino7 for now. I honestly cannot work like this.

Got it, a reselection of the selection shouldn’t be required. Thanks for the input.

The initial soft selection you are seeing (where you have to then select again in the UI to delete them all) can be hard selected by the ‘Get Selection from Viewport’ located in the hamburger pulldown

Thank you Japhy, that is helpful to know. Ultimately though it’s an unnecessary extra two clicks.

What was the idea behind the extra additional highlight state? What is it intended to be used for?

To have it goes against the Windows standard that has been established and used by people for decades.

The old BlockManager UI is gone in Rhino 8. The functionality has been reproduced in the Panel UI, albeit slightly different. I’m going to add feature request to get the ‘Get Selection from Viewport’ functionality added to the Right click menu as well.

Thank you, but instead can we please just have the previous RH7 selection behaviour back?

I don’t want to have to right-click first in order to reconfirm a selection I have already done.

Again, what is the use of the semi-selection-state?

It highlights the selection and allows the user to refine from there vs deselect then do something, which would be required on a full select, IMO.

Okay.

Personally I don’t think that behaviour makes sense and the handling was better in Rhino7, but that’s just my opinion.

I’m not sure if it’s possible, and it seems too late now, but it would be wonderful if McNeel could give more importance to testing these changes with select users ahead of implementing them. I’ve been working with blocks in Rhino for 10+ years, and at this point my files are mostly blocks and nothing else. I would be happy to give feedback and input for testing purposes.

Thanks, I think i understand the issue and will illustrate the differences in a feature request and see what can be done.

ExplodeBlock command … Purge/BlockDefinitions …


Yes I know a workaround like that, but it’s very undesirable when the ability to delete multiple blocks at once had been present for years. It looks like it was removed by an oversight which saddens me.

I usually do a mass deletion of all blocks, but you can obviously select whichever blocks you’d like.
