1. ## need help...How to create a shift knob???

Registered forum members do not see this ad.

Im trying to create a car shifter knob. its not a uniform shape.

here is what the iso and the side view looks looks like.

I created these shapes by making half of it flat in 2d then revolving it 180°. then i put them back to back. but as you can see them do not mesh correctly. how can I create these shapes so they can mesh nicer. Im trying to learn how to create complex 3d objects, but obviously im not very good at it. Are there any tutorials where I can learn some things.

See tutorials in my signature. Looks like you want to learn Loft.

ive tried the loft, unless I dont understand how it works. It tells me that the surfaces are non planer.

You forgot to attach what you have so far. I doubt anyone can give much help without seeing where you are going wrong. Not even a picture of your loft attempt.

Did you actually go through and do those tutorials I suggested?

5. how can i upload it, even a zip is larger that the max allowed size???

6. post a screen shot of the profiles you are using for a loft. Start out by drawing 4 circles. one at 0,0,0, one at 0,0,5 ,one at 0,0,8 and the last at 0,0,9. make the bottom circle diameter 2", the second 4", the third 3" and the fourth 1". Loft, select your circles in order from bottom to top. You should then get a dialog that will let you create a thing surface, solid, let you state how the loft should enter/exit each profile etc. If this works out, play with creating paths and guides.

Can't possible be too large. The only thing that is needed is the profile sections you are trying to loft - nothing else.

If it is still too large I would be very interested in seeing a screen capture of that one. My guess is way way too much work. The biggest mistake people make in Loft is too many splines or too many points in splines. Actually makes rougher model rather than smoother.

8. here it is. you can see i tried to make 2 2d views the side view and the front view. then I rotated one 90° and started making the green splines around it to create the shape. but how do I convert the splines into a solid object?

9. forget what you were doing there and start over.

create a loft from the bottom to the top. Follow what i said for a simple loft. Your loft will be driven by cross sections, path and guide curves. I had you drawing circles but any closed profile will work. You need to know how to close a profile using the Region command, or PEDIT.

I read the help, and I still dont understand how to use the loft. what objects in this drawing should I be using. the sections that are laying flat or the ones that are perpendicular to eachother that are standing up??
