Hi Michael , I made this little video to show you my request.




Whai I want is to be check box that will delete base surface/cap that was used to extrude/shell.

May be - Cap 1, Cap 2 check boxes?

Hi Andrei,

> May be - Cap 1, Cap 2 check boxes?

I can understand that would be helpful for that particular situation you're showing there, but it would unfortunately make things more complex for other situations like if you just want to extrude a non-capped surface now you have 2 checkboxes you have to uncheck to turn off caps, and then again if you want capping later on you have to check two boxes then to re-enable it...

I would like to make it easier to make pockets like you show there, but I'm hoping to do it at a kind of higher level where you could produce it directly from a 2D profile curve rather than having to do a separate step to trim out a surface fragment like you have in your first example.

I'm hoping that might be some kind of "limit depth" option when doing a boolean possibly.

Also I'd like to make some way for an extrude to be automatically booleaned with another object. I'm not entirely sure yet how to activate that, I had been thinking of doing it automatically if you had a solid selected in addition to the thing being extruded, that might not help in some of your examples here though where you only have a surface as the base part instead of a solid. Right now a solid being selected in Extrude does not do anything to the solid, only surfaces or faces can be extruded and not entire solids, so that's why it might work to use that as a signal for what to combine the extrusion with.

Michael, why not to make when you check - Cap Ends, apears new two check boxes - Cap 1 and Cap 2.

Who never use it will never tuch those Caps check boxes, but who use will check them if needed.

Hi Andrei,

What would then happen if you checked "Cap Ends", but then unchecked "Cap 1" and "Cap 2", does that mean cap ends is on because "Cap ends" is checked or does it mean it's off because "Cap 1" and "Cap 2" are un-checked?

It's kind of weird to have UI structured in such a way that it can look simultaneously on and off with nested controls like that...

- Michael

Then make just one check box - Disable base surface :)!

Or... make it impposible to uncheck both caps. Only one can be unchecked to disable both you have to uncheck - Cap Ends.

Or if you uncheck both caps, Cap Ends unchecked automaticly and next time when you check it it will check both caps.

I think - Disable base surface, is the best option :)

These sound like UI that would not really behave like any other checkboxes in the system, that kind of thing tends to easily lead to a confusing UI.

I'd still prefer to focus on other better ways to achieve the end result rather than a special option that only eliminates one individual step.

It would be better if you could make a raised or indented area directly from an outline curve and avoid several of the other steps as well.

Or also another thing that might work is to automatically do the "disable base surface" thing when you are extruding a face that is part of a joined structure.

- Michael

Michael, What do you think if it will automaticly "disable base surface" if you extrude frome surface, joined surface and edges?

Hi Andrei,

I don't get this, by the time I work out which check box to check or uncheck I can delete the unwanted face just as quick.
I just want to understand the reason for your request.

DannyT,
becouse:

1. You can not see how deeper it goes
2. Check my example here a lot of pecise and you have to spend time to delete them all...

I just show this request in the start of topic on simple example but during work there are more complicated stuff even then I showed in this screen...

I meet this chalenge quite often, so thet is why I asked for this...





Check this model it has A LOT OF stuff like this...Windows, doors, grils etc, etc... So to have this feature will make life MUCH more easer.....

Hi Andrei,

I see what you mean, however for grooves like around the door I would use Construct > Offset > Inset.

Hi Michael,

Having a look at Inset and when 'Use separate height' is checked is it possible to have a zero thickness, at the moment it's not accepted, in that way I think that would suit Andrei's request.

Agree with DannyT

It would be nice :)

DannyT, good idea!
for me it does not matter what it will be Extrude, Shell or Inset, the main thing is - it should work in this case:)! So waiting for Michael reply.

I think this is what I asked about here http://moi3d.com/forum/index.php?webtag=MOI&msg=5508.8

Probably not for individual surface or edges since those can often be used for just regular simple extrudes where people are trying to generate a solid, but I think that it might work ok for the case of extruding a face that's a part of a joined surface.

I don't know... Inset is primarily focused on generating a border, with the border thickness as it's main input field at the top of the command.

So it seems kind of awkward to focus on disabling thickness inside of it. For example since the command is primarily focused on thickness when you pick 2 points with the mouse it sets the thickness, not the optional "separate height" height.

It seems like it might fit better as an option in Offset, maybe something like "build side walls"... The thing that makes me pause about that is that there is then some duplicate overlap functionality between offset and shell, since if you select an entire surface object Shell will thicken it with side walls constructed already. The main difference would be the behavior when there is a face selected instead of a whole object selected, shell uses that as the opening and thickens everything else.

Michael, if it is so problem for you to incorporate this command into existing ones, could you pleas make just script without any UI icons, just script.
In wich you can shell/extrude without base surface.
