    Hi... I think it's better if I make separate thread and put the links here to my custom and in the custom make a hyperlink to here :D

    Build in K-3D just started today never modeled before (did use DAZ3D, but only used primitive and once made a WALL-E figure ;)  most of the time I was just having fun building scene's and rendering pics) and never used this program I also did use any tutorial or manuals (YET!)

    Seems like the only big problems I encounter is a way to CARVE, If heard and viewed a youtube video years ago that's how I now of a sort function...
    When you have for example a SPHERE and 2 small cubes... place them into the eye-sockets... select the cubes and "carve" which leave 2 holes in the SPHERE, but can't seem to find a similar option :)

    Sounds like subtraction. That is usually part of the boolean operations. Don't know about K-3D though.

    yeah subtraction that's the term thanks no I have to google it :) 

    EDIT: found it... now to look if the program supports it ;) 

    Boolean Operations
    The starting point of Boolean operation is two overlapping 3D objects. Boolean operations are prone to error and the resulting geometry might have underlying problems.

    Boolean operation has four possible results:

    Union: Two 3D models are combined and the unnecessary geometry inside of the Models is removed.
    Intersection:
    Overlapping a part of the two 3D objects
    Subtraction (A-B):
    Object A is subtracted from object B
    Subtraction (B-A):
    Object B is subtracted from object A

    F*CK this is not gonna work :(

    CGAL Boolean Operations - K-3D

    I'm gonna be searching another program that does support this function!!
    ANY TIPS ARE MORE THEN WELCOME :) 

    Is Google Sketchup able to do this operation?

    Since you're using K-3D I assume you're using some kind of linux machine.

    In that case I'd recommend blender, even though it has a steep learning curve. The function you're looking for is called difference there.

    Do inward extrudes. Never ever use Boolean. I screws up the mesh so badly, it'll never be able to be printed properly.

    I use booleans for my stuff, case by case. They can work, if you know how to handle it. And it won't screw up your mesh. You'll just have to do some cleanup, which can be very quick. :D

    any chance you can give me some example, how do I know when I need to clean-up for instance and how do I clean-up :D 

    btw no I have the Windows version of K-3D,
    but I'm willing to try other programs... I learn very quickly ;)

    Ok, hopefully this makes sense.

    Lets say, you are going to subtract a cube piece, out of a sphere. Instead of subtracting the cube out of the entire sphere, you select the polygons on the sphere, where the subtraction will take place, and extract them as their own model. That way, you have two parts of the sphere. The area you will subtract, and the rest of the sphere. Then, just do the subtraction of the cube with the part of the sphere which will be subtracted from. Once you run the operation, then you combine the sphere parts back together.

    If you get this "idea", then you can easily apply it to any complicated and poly heavy model. If you have played with the boolean tool long enough, you will notice it will alter the geometry on a model, even where the operation did not take place. If you try this idea, of extracting part of the model out, it will do less damage.

    There have been times, where a model would not even accept a boolean operation for me. But when I separated the area where the operation took place, it worked really well.

    As for cleaning, just delete "edges/lines" that are no needed. Boolean operations will add extra edges/lines. You can just easily delete them. With my method, it will be less work, as you only clean the operation area, instead of the entire model.

    This method only works, if you area doing a boolean operation in an isolated area of a model. If the boolean operation will affect a big chunk of the model, my method might not work.

    One tip for modeling overall, is to keep the model basic, in detail. For example, if you have a model, where you beveled the edges, then apply a boolean, it will screw up the beveled edges. However, if you apply the bevel after the boolean, it will work better. Keeping your model simple, until the end helps. Especially if your still shaping. With details added, before you finalize the shape, it makes it harder to work with. Details are easier to add at the end, and will cause less problems. :)

    100% understood :D  problem is my program won't allow it :( 
    any tips on a easy/good/versatile 3D modelling tool for TF-purposes ;)

    jeez that program is not what I thought it would be...
    good for fun, but not for what I'm looking for...
    now installing Sketchup Pro 8 :p
