I can not get my head around this random way the selection tool works, not works at all, half works. And even this: it does not work. Yet it does. But not really.
Please see this:
These are curves that were extruded in one go. They must be identical. Yet they behave different from each other when you want to select.
Selection in general has been a pain for me in Rhino.
This is my selection filter:
First, posting a file rather than a video will get you a much better analysis.
Second, you have subobject selection checked in your selection filter. You might want to look in the Help to see what subobjects are and what checking the subobject filter does. If you uncheck that, what happens?
Not necessarily, it depends on the quality of the curves.
They are likely not all the same, it depends on the quality of your curves, some of them appear to have made polysurfaces when extruding (possibly because of kinks in the curves), so they are not simple surfaces or extrusions. Simple extrusions will not select when the subobject filter is active. Parts of polysurfaces, will however, which is what you appear to be able to select…
Sub objects was on. Apparantly that causes this behaviour. Still weird why it would half select SOME of the items. But it is solved for now. Thanks for the quick reply!
Because some of them are polysurfaces and some of them are extrusions. Check your input curves on those that produced polysurfaces - they have kinks at the joints. When subobject selection is active, it will select the component parts of a polysurface, not the whole thing. It will not select simple extrusions at all.
Also, suggest you turn off extrusions - run the command "UseExtrusions and set it to “Polysurfaces”. It may be less confusing after that.
I have been looking for a good selection tutorial. Could find something about selection commands but not really the specifics of how you can make it work. Apparantly they made a whole thing about this selection you first have to understand their logic behind it. This is what i mean:
Another example. For me as a novice coming from 3DsMax this is very weird why they do not make it work on default but you have to mess around with the selection filter. But then you turn on points there and even then you can not select points. You know what i mean? It is very funny how they made this.
Is there some way to disable the selection being default off / not working?
Do not assume Rhino works like 3DsMax or other software you may be familiar with.
No, you don’t… Perhaps you need to have a read through the introduction material for Rhino to see how it works.

The purpose of the selection filter is to limit the selection to certain types of elements. If the selection filter is not active, everything is selectable - except for locked objects or those on locked layers. So, just turn off the filter for now (click in the status bar pane so that it’s not bold and that the filter box goes away).
Thanks for the great tips. I have read the documentation, I read: “Select the sheer curve and press F10 to turn on its control points.” Ok so you have to press F10 otherwise it won’t work. Riiiight… Man who would have thought! F10 it is.
In Windows F10 turns on control points for any object that can have them. For curves, you can set them to turn on automatically when you select the curve in Options>Mouse. (personally, I’m not a fan, but YMMV)
You can also use the toolbar icon to turn on points or change the hotkey from F10 to anything you like.
