Something like extendsrf for subd?

[phcreates (peter harris)]

Is there something like extendsrf for subds?

[Tom_P]

can you give a sample (3dm file) you re after ?

check out
_extrudeSubD
(use the edge “to extend”) use Direction UVN → V

for other cases it might be more adequate to build a helper-surface Stripe and then
_bridge

does this help ? kind regards - tom

I tried using ExtrudeSubD and I don’t like the result. It certainly isn’t a substitute for Extend.

In the attached, the red subds were made by ExtrudeSubD. The green subds is what I’d expect an extend command to do. I would want it to extend based on the box edges, I think.

we do you create a similar topic for the same aspect ?

Wish: SubDExtend

Similar to how Extend is useful for surfaces, I’d like to be able to select an entire edge of a subd and extend it like in the attached. I realize that a smooth option might be tricky because subds don’t have UV direction, but I’m thinking it might be pretty easy to make a Straight extend option at least. And maybe options for just stretching the selected faces vs creating new faces that are joined vs creating new faces that are unjoined? I tried SubdExtrude with V option, and that result is us…

@phcreates

Straight extend option at least.

my 2 cents - - an algorithm might not guess what the user is after. Most scenarios will require to move or adapt the result…

regarding your straight option:

did you try
_slide (the input edge to extend the faces)
_insertEdge (“divide” the extended faces)
i think this is closest to what you re after ?

i would appreciate to keep one topic for one aspect - so if someone of mcneel might merge the topics ?

@Tom_P the topic I posted first was a question to find out if an appropriate tool already existed. The new topic is specifically a request for a tool to do what I need, which I posted in the WIP forum. I think it is clearer to have a post that is specifically a wish than to tag on a wish in a post asking for knowledge. I understand that you’d appreciate that I post in a different way, but your opinion isn’t really relevant. McNeel can move it if they want to, of course.

Slide does extend the right way. For some reason, it only lets me slide a short distance but it does work much like my request for an option to stretch the selected faces. It would be tedious to do slide and insertedge every time in order to accomplish creating new faces that are joined. But, yes thanks, this method could work for me for the Straight option. I didn’t know Slide would work to move edges beyond the subd border!

If you enable gumball mode to object, and select the control points, moving with the gumball is quick and easy (similar result of Slide) then you have to re-insert the edges…

@maje90

mode to object, and select the control points,

… wip / rh9 !!!
nice

[phcreates (peter harris)]

That is a good way to do it. I just have to remember to select the points and not the edges! Hmmm…
