F J Posted January 3, 2008 Share Posted January 3, 2008 i guess this is how it all starts i just built all the 2D on this house, now that im on to the 3D i realise i dont know how to make a surface! LOL ok, picture a rounded corner wall, like 1/4 of a donut.. i used 2 arcs and 2 lines.. obviously thats not a shape, its just the lines.. so i tried converting 1 of the lines to editable spline then attached the remaining 3 lines to it.. then i welded the vertices where the lines connected, but its still not a shape damn i thought this would be easier lol ok, who wants so shed some light Link to comment Share on other sites More sharing options...
notamondayfan Posted January 3, 2008 Share Posted January 3, 2008 have u applied the extrude modifier to the spline? Link to comment Share on other sites More sharing options...
F J Posted January 3, 2008 Author Share Posted January 3, 2008 yes, the extrude with 0 amount will result in a shape, but is this the only way? Link to comment Share on other sites More sharing options...
chiquito Posted January 3, 2008 Share Posted January 3, 2008 are those line well drawn? if so, check one, go into edit spline, click attach, and attach this lines. next apply an extrude modifier. if it extrudes, you are happy, if it doesn't, you have an issue in the vertices , select all of them (go back to edit spline) and weld them. check again, that should do.

chiquito Posted January 3, 2008 Share Posted January 3, 2008 you can also outline, or go further into polymodeling... but better learn to extrude first. Link to comment Share on other sites More sharing options...
F J Posted January 3, 2008 Author Share Posted January 3, 2008 you can also outline, or go further into polymodeling... but better learn to extrude first. what do u mean "learn to extrude"? lol i just said that extruding the spline with 0 amount will result in the shape.. as for the outline it wont get me any shapes, just another spline as if copied n scaled up or down.. finally i was able to transform it into a shape converting the editable spline into editable poly.. mission accomplished i guess thx all Link to comment Share on other sites More sharing options...

BrianKitts Posted January 3, 2008 Share Posted January 3, 2008 i just said that extruding the spline with 0 amount will result in the shape.. a more appropriate way to do that would be to apply a "surface" modifier to your object. I would think an extrude of 0 amount would create two coplaner faces... which is just bad modeling. Link to comment Share on other sites More sharing options...
Claudio Branch Posted January 3, 2008 Share Posted January 3, 2008 ok, picture a rounded corner wall, like 1/4 of a donut.. i used 2 arcs and 2 lines.. obviously thats not a shape, its just the lines.. so i tried converting 1 of the lines to editable spline then attached the remaining 3 lines to it.. then i welded the vertices where the lines connected, but its still not a shape What you are describing here sounds like a plan section of 1/4 of a tube (not a donut). You have attached these shapes into a single entity and welded the vertices. So now you should be able to Convert to Editable Poly and extrude this single polygon to whatever height you need. Post up a reference image if you need more assistance... Link to comment Share on other sites More sharing options...
RodT Posted January 4, 2008 Share Posted January 4, 2008 another approach would be to try the loft. you can assign your welded spline as the path with a cross section of your wall Link to comment Share on other sites More sharing options...

I would think an extrude of 0 amount would create two coplaner faces... which is just bad modeling. i dont know if its a bug on my end or not but as soon as i added Surface Mod my spline disappeared..

So now you should be able to Convert to Editable Poly and extrude this single polygon to whatever height you need. Post up a reference image if you need more assistance... ok, i'll post a screen of the shape im talkin' about, but it can be any shape really, like the topic says "create surface from lines".. all i want is to be able to create any surface from whatever group of different lines.. i just assumed that once i closed the shape with the lines n welded those corner verts it would automatically be a surface.. like i said before, 2 arcs + 2 lines, converted 1 arc to editable spline n attached the remaning 3 to it, then welded corner verts, but it still wasnt a surface.. only way it changed into a surface was either add extrude mod with 0 amount or convert final shape to editable poly.. another approach would be to try the loft. you can assign your welded spline as the path with a cross section of your wall nah, no lofting.. wanna try n keep it simple, as it should be, the way i see it.. like i said: "i just assumed that once i closed the shape with the lines n welded those corner verts it would automatically be a surface.." but i think i got it going now, one way or the other.. PS: if an X should arise instead of the images just try right clicking the X then properties n copy the image link, thx.. Link to comment Share on other sites More sharing options...
chiquito Posted January 4, 2008 Share Posted January 4, 2008 Are your lines in two planes or in a 3 plane arrange? if its 3 plane, you could also give a try to nurbs. any additional info? Link to comment Share on other sites More sharing options...
F J Posted January 4, 2008 Author Share Posted January 4, 2008 Are your lines in two planes or in a 3 plane arrange? if its 3 plane, you could also give a try to nurbs. any additional info? what is 2/3 planes? all i see on those screenshots is 2D, viewed from the perspective viewport..

chiquito Posted January 4, 2008 Share Posted January 4, 2008 What I meant, is that the lines you have drawn, could be (don´t know if its the case, hence may question) drawn in 3 planes, 3d, or in two planes, 2d. Link to comment Share on other sites More sharing options...
notamondayfan Posted January 4, 2008 Share Posted January 4, 2008 for the surface mod to work, you have to have 3 or 4 sides shapes within you spline. in my attatched image, the shape on the left wont work with the surface mod, but the shape on the right will...

notamondayfan Posted January 4, 2008 Share Posted January 4, 2008 once uve drawn your outline splines, use the "create line" in the modifier panel (selecting your spline 1st ofcourse), then turn on snap, and create a mesh looking design between your origional splines. do a google search on spline modeling and you should find loads. its used quite a lot in facial models, but the theory is still the same.

Guest nazcaLine Posted January 4, 2008 Share Posted January 4, 2008 you have to create a "spline network", that means all splines must be only 1, (i mean attached to form only 1 shape). also, make sure there are no vertices alone, i mean all line vertices should be coincident with the others' vertices.for example, a vertex from a spline can't be placed in the middle of the segment of another spline. if the surface doesn't appear, that can only mean there are left vertices. i hope i made myself clear Eduardo Link to comment Share on other sites More sharing options...

Peter M. Gruhn Posted January 7, 2008 Share Posted January 7, 2008 I'm curious if extrude with a positive non-zero number isn't good. If so then we may have a communication error here. I don't know what you mean by "shape." Why is the welded spline object not a "shape"? Lots of words mean very specific things in this field and, worse, different things in different software.
