Talk:Blender 3D: Noob to Pro/Simple Vehicle: Seat

Extruding the seat
Like others when I did it the first time, and extruded in "vertex" selection mode, and picked "regions", the loop cut made a funny triangle shape on the back of the original cube, this is because I was extruding regions, and had created alot of doubles, some with reversed normals.

A better way to do this and not create doubles is to go into "Face" selection mode, then you will be extruding faces, and not wind up with a ton of doubles, some of which will have the wrong normal’s, and make your loop cut act funny.

If you insist on using edge mode, or vertex mode, you want to only pick "Faces" from the popup menu that appears after you hit the EKEY, this will stop the doubles from appearing. If you don't see Faces on this menu then you are really extruding from doubles with reversed normal’s, so go and remove them ( W -> remove doubles ) before continuing to extrude.

Yoshi's Addition (leather look)
After subsurfing to give the seams a leathery cord look. Hit A to select all then W and Subdivide Fractal and just keep the defaults and the seams will look like a bunch of vines until you render it and they look like leather seams.

older issues caused by doubles, or interor faces, during extrusion
In blender 2.45, I tried getting into the wireframe mode, but didn't find any internal faces. Maybe they don't exist in all cases. MSK61 (talk) 16:20, 12 May 2008 (UTC)

I also use Blender 2.45 but I managed to find some internal faces (in the loops) and deleting these really did clear everything up. I was already wondering why my model looked so wrong.

Viewer: Selecting all(AKEY)Pressing WKEY and selecting "Set Smooth" helped me a lot in the looks.

Noob note: You should remove doubles at this point (TAB to edit mode > WKEY > Remove Doubles). When I removed doubles before adding the loop cuts, I found that they did not loop around the bottom of the seat correctly, and when I did not remove the doubles at all, I had trouble forming the seams in the next few steps.

Noob note: I had to remove all faces inside my seat before loop cut works (and in object mode I join all faces Ctrl+J)

-- Noob note: Also you could try deleting faces and edges which are unused inside the object (seat) this way there are no edges to cut up the loop into lots of different sections, so now you will have one clean loop :)

-- When I tried to subsurface I had the problem that my extruded cubes only subsurfaced smoothly into the cubes that they were extruded from. I wound up with big dents in between the different sections of the seat (it actually came out looking like a pretty good hand) and I have so far been unable to remove them)

Try selecting all vertices (AKEY) and remove all doubles before applying the subsurf mod, this helped in my case...)

User: Thank you that did fix my problem. My seat still needs a lot of work with creasing to look like the final picture but at least it isn't a deformed hand anymore) end user feedback.Feureau 00:24, 24 March 2007 (UTC)

- I am having a terrible time with loop cutting on this project. I could do it fine during the dice tutorial. And after extruding the multiple cubes for the car seat, setting edge mode, selecting ctrl-Rkey, and hitting the 4key, the four parallel lines loop cut lines are still fine. Once I hit  or LClick however, all loop cut lines suddenly run symmetrically at an angle towards adjacent vertices. I've tried doing a loop cut after each step, which usually works fine. What I can't figure out exactly is why and when the loop cut changes in this way.

2008-07-19, Same problem as the user above (I'm using blender 2.46). I used the multicut tool instead. I have no idea why the loopcut didn't work.

-- I'm little confused when it comes to loop subdivide... First of all after creating whole seat I hit "remove doubles"... Then loop subdivide didn't work as it suppose to (it took me about 30 min to realize it...). When I thought that I can't remove doubles before loop subdividing I would like to know how to add loops to all blocks in the center instead of hitting ctrl + r to every single block?

Ctrl + R (cut) started to work properly when I extruded regions only (Blender 2.48a).

-- I moved the following user comment here because I think it does not belong to the articel, since loop cut does work in 2.6x, 91.66.152.41 (discuss) 10:41, 20 May 2013 (UTC):

Version 2.60 user comment: I tried several different edge loop, loop cut, loop subdivide, etc. to no avail, so I selected all the edges of the middle portion of the object (seat) using box select, then I Knife Cut (hold down Kkey and LMB through the front view of the edges from top to bottom. Select multi-cut and number of cuts to 4.
