# Just some questions...

How would your aproach be to do an mesh(with out using nurbs and curves, etc) like this one?
(it’s from Silo homepage’s)

Why can’t you use curves then hit alt+c?

I agree… This looks like a simple 3 point bezier curve converted to a mesh.

HOWEVER, since you asked for a mesh only.

Add a plane and a circle, delete 3/4 of the circle and 1 vertex of the plane.

Move these two objects so they line up correctly, use “f” to join the 2 edges of the plane to the circle.

Make faces and then extrude.

Pretty simple but I really like curve for this kind of work better…

Two ways:

simple subsurf with zero length extrusions for sharp corners

It was mostly curiosity, because i was trying Silo, and that shape it’s really easy to get, just get a cube and subdivide two faces various times.

So I just wanted to know if you could do it a really quick and easy way, and using curves will take more time that what I wanted.(Yeah I wanted it really quick! but prolly Blender masters can do it really fast with curves but I can’t )

So the simple subsurf and stuff that GreyBeard suggested is what I’m prolly looking for.

Also I’m curious now, Is there a way to convert a subsurfed mesh to real mesh?

Alt+C converts nearly anything to mesh (well, text goes to curve first)

To create that shape with curves:
Press V to break the tangents
rotate by 45 degrees
remove one point
move 2 handles to get the curve you want

Or, alternatively:
remove the points on the sides of the “square”, leave the 4 corners
Change the weight of 3 of the corners as high as it will go

I got the Bezier way of doing it, tought I didn’t got the NURBS way of doing it… I’m good with meshes and a lil good with Bezier but not with NURBS haven’t played enough with em before

And about doing it using Bezier curves, you also have to convert to mesh and then extrude it to get the shape.

But it still can’t beat making a cube, pressing D(to get face selection mode), then shift + a mouse click on each face to select, and pressing alt + C(subdivide) 3-4 times, like you do in Silo.

It’s not like I’m thinking about moving to Silo, I love Blender, just curiosity, and besides Silo is just a modeler and his strong point is supposed to be partially in subdivision.

No need to convert to mesh
Just set the “Ext1” value in Editbuttons

About the simple ’ subsurf with zero length extrusions for sharp corners ’
it might sound silly but I haven’t understood how to achieve it. Althrought I understood that it was just making a cube, subsurf and changing a value, that’s why I said it was quite fast. The part that I don’t get it’s the zero length extrusions part, where can I change that value? :o

Zero-length means that you don’t move the vertices after extruding. Just select a face, press E, Enter and Esc.

To explain my comment on zero length extrusions. In subsurfing the closer 2 edges are together the sharper the crease will be. If the two edges are on top of one another you get a perfectly sharp crease. So select a face of the cube, extrude and just press escape – this creates a new set of verticies on top of the originals creating sharp creases in your subsurfed object.

Note: make sure you don’t remove doubles on the object or you will lose your sharp creases. In practice I almost always extrude a tiny amount to create a small bevel – there are no perfectly sharp creases in nature.

eg.

edit: If you check the news and chat forum you will notice that some testing builds already have true adjustable creases for subsurfed objects like in Maya and Silo

wondering if this is still the case with 2.33

Subsurf ->catmull Clark or Simple subdiv??

I am tryin go to get

do i extrude a face (so 4 edges) or just a edge???

With the new build from news&chat, or in 2.34 when it comes out:

Catmull-clark subsurf
Select all
Shift+E, make the number big (ideally infinite)
select just the two verts in the top left
Shift+E, set to 0

Simple subdiv doesn’t smooth the mesh - it just adds more verticies for thigs like displacement maps and rendertime radiocity.

This feature is not in CVS. AFAIK, it still needs much checking up and is not a 2.34 target. It will depend on when 2.34 “ships” though.

Ah, I thought it was in the bf CVS tree.

So it’s just in those released builds then? or is it in tuhopuu?

Neither. It’s a patch that some people choose to apply to their release.

Martin

hmm,

I am trying to follow you, “OG” blender guys, but you guessed i can’t.

Philip, i am using 2.33a

Select all and Shift +E (doesn’t do anything)

With shift + E do you mean just E (extrude)?

This is a simple object or not??
