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.
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
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.
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.
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.
