Polymodeling this roof?

Hey guys,

 

I just created a puzzle for myself and it's absolutely driving me crazy. I made this roof in about 2 minutes in sketchup...but I want a neat mesh. When I tried poly-modeling this, I could make the main gable fairly quickly and neatly...but when I do the smaller eye-brow gable on the side, it totally screws with my quads. Does anybody have any idea at all how you would go about doing this?

 

BTW, I'm pretty sure that this is independant of any software as long as it's a strong modeler (MAX, Maya, Blender, etc)

 

Thanks so much.

 

PS...And I can't export the roof from Sketchup, because I only have the free version...plus I want a clean mesh.

All you need to do is 2 extrusions, a union and 2 subtractions (if using autocad) but I am sure you can use the same method in 3d studio or any other modeling software.

Make the extrusion with the profiles of the red and blue lines (see attachment) and make a union of them into 1 solid, then extrude the yellow lines and use them to subtract form the main solid.

The other image shows the result using autocad

Hope this works

Wow guys...thanks SO much for your time...I'm going to take a look at these when I get to work tomorrow.

 

POCO...Is that a clean mesh? I was trying to avoid Booleans so that I could stick with quads.

Booleans in ACAD rock...they are very clean.

Yep, its a clean mesh made in 3dsmax, no booleans were used. There are although 2 triangles in the little roof.

creating roofs with quads is not difficult but just out of curiosity, why would you even care when creating roofs? it has no bearing on anything that I can think of.

 

incidentally, here's a free chapter on creating roofs if you have seen this already. click on the free sample chapter for the intermediate to advanced book. http://3dats.com/products.asp

there are several good reasons for working in quads, such as -

 

smoothing works so much better

editing the mesh at a later time is easier

adding detail like chamfers is easier

it looks neater

it will export better

some realtime applications work better in quads

Thanks for the file, Poco...now I just have to reverse engineer it. I realize that roofs don't need to be that clean, but I'm actually trying to do this for my own personal project. Therefore, for the sake of learning and improving my skills, I'd like to keep everything as clean as possible. For myself, the final artwork would be a lot more rewarding, but I realize that others would view that differently.

 

Thanks for the link to your book, Brian.

not going to argue with your list, but what few extra edges are created can be removed with the edit poly in just a few seconds.

I am SO GLAD I pre-ordered this back in January.

 

Eagerly awaiting it's release. I hope to devour it cover to cover in a weekend, then work back through it.

yeah we went through our limited advance copies...which are airmailed one month ahead of the slow boat from china.

 

i would be amazed if you could gobble up all of this stuff in one weekend. you'll have to go without sleep to do it.
