Hey Igor, where did you dig this thread from ? It's like pulling out an old photo album on MoI as a baby :)

Ok, while I'm here, I wish for peace on earth...............Oh! MoI wishes.

Hi Michael,
There is one feature I do like from other modeling programs and does come in handy for repair work and that is, enlarge a surface.
In it's simplest form you pick a surface and it creates an untrimmed copy of the original surface, which would be one thing. In it's advanced form once you pick a surface, an untrimmed copy is created but then you have U and V sliders to enlarge or shrink that copied surface.
Is this possible with the geometry library MoI uses ?

--------

Hi Danny, yup that is possible with the geometry library tools. The bigger issue can sometimes be about setting up the UI for such things.

This part you can actually do right now by using the "untrim" operation in MoI. To do an untrim, select all the edges that make up a trimming boundary and hit Delete, that will remove that boundary and recover the underlying surface.

The edges must not be a joined edge between 2 surfaces though, so you may need to delete some surfaces or use Edit/Separate on any joined surfaces to break the edges you want to remove to not be connected to other things.

Also if the trim boundary touches the seam edge of a closed surface, the seam edge is part of the boundary and should be selected too.

The easiest way to remove everything is to use Edit/Separate to make the surface into a single unjoined surface, and then select one edge and then hit Ctrl+A to select all edges and then Delete.

Check out this previous post for an illustration on untrim:

(EDIT: I just saw on another recent message that you definitely knew all about this - are you asking for something different with this extend mode than what can already be done with "untrim" / delete trim edges ?)

This one I'd need to think about the UI for a bit which may take some time... Probably it could go in the Extend command, but then when it goes there it may be good for it to have several modes like an "extend to boundary" mode like the regular curve extend.

Well, sort of, it does the same thing but without going through the paces of separating, picking and finding all the edges, and you always miss that tiny edge, then deleting.
Where with an enlarge button or even a script for now, it would be; execute command, pick surface, done.

For the second part, extend a surface to a boundary sounds interesting, I don't believe I've seen something like that.

Cheers

Hi Danny,

> picking and finding all the edges, and you always miss that tiny edge,

For now at least, this particular stage can be simplified by using Ctrl+A (or in the side pane, the Select / Sel All button).

If you have an edge currently selected, then select all will go through and select all other edges on that same object, and when you have edges selected it will not go through and select other regular objects.

That will be guaranteed to catch all edges of a surface, including tiny ones.

I didn't even know that you had Ctrl+A in MoI so refined, I missed that one along the way :S

What do you mean, For now at least ?

Thanks

Hi Danny,

> What do you mean, For now at least ?

Well, I mean I probably won't be able to work on stuff for Extend here in v2 since I am trying to wrap it up. But maybe I will be able to make progress later at some point.

Until I have a chance to do something different, using Ctrl+A can make using the current untrim function easier.

Hi Michael,

> Well, I mean I probably won't be able to work on stuff for Extend here in v2..........

I hope I didn't come across wanting that feature now, I was actually referring to how you've made Ctrl+A like a chaining function after selecting an edge of a surface,
I thought you had some other ideas on chain selection of curves and edges.

--------

Hi Danny, no I didn't think it sounded like that, I just wish that I did have time to work on that right now...

> I thought you had some other ideas on chain

Yeah, I do want to have some other tools for that, something like grow a tangent chain off of an initial selection.

Ctrl+A is just meant as a way to grab all edges easily, not so much as a replacement necessarily for directional type chaining, although for some cases they would be equivalent.

French Version of the ScaleArray! :)

Hello Michael,

Is ScaleArray compatible with V4.0?

Hi Psygorn,

re:
> Is ScaleArray compatible with V4.0?

Yes, I just tested it to verify. Note that the way ScaleArray works you need to include a point object in the objects being arrayed. That is used as the origin of the scaling.

- Michael

Hi Michael,

I had downloaded ScaleArray.zip and then unzipped it. then added "_" at the beginning of the names of "ScaleArray.htm & ScaleArray.js" files then put them in the Command folders.

However, I think I don't know how I should include a point! I know ScaleArray will work after a directional array is made but should I add a point using Draw Curve>More>Point , Because I did and then used ScaleArray but I saw no changes in the objects!

What am I doing wrong?

Hi Psygorn, did you add just one point after doing the array? If so then that's the problem - you need to add the point in before doing the array and include the point in the array operation as well.

Then select all the arrayed output including the arrayed points and then run ScaleArray.

Ah ok, Thanks, now it works :)
