rotate/cut mated cone? How

[bline1112]

Hi,
I am a Solidworks user since 1998.
I have never tried to perform this particular function.
I am working on a design for a pool cue (for myself) which is a cone.
I began with a part, created a moldbase, and then mated the two in an assembly. Now I am trying to revolve/cut the 1.375" x 1.375" x 15 forearm to a cone to see what it looks like when turned.
I tried an extruded cut and revolved cut, got a interior hole of the right shape but need to see the negative of the result.
I tried a drafted cut and it only worked on one piece of the mated assembly...won't let me do the other piece.
Is this a loft? Sweep?
Sorry for the elementary question but I'm stumped.
Thanks in advance for all replies.
Regards,
HA Bruce

Bruce...

Im a little cornfused...

Sounds like you have create a conical shaped part and you want to make a potion of it cylindricaL? Im not sure exactly what the shape is that you are looking for...

I can help you once i understand the task at hand!

You say you " tried an extruded cut and revolved cut, got a interior hole of the right shape but need to see the negative of the result."

Well what about editing the definition of this and check the Flip side to cut check box?

As far as the geometry you're describing, unless your after a cone shape cut inside your cone solid, I'm in Jon's corner.

Ok,
I didn't describe it very well, did I? Sorry...
I am trying to describe/communicate the joinery (standing on its end, a top and bottom half that fit together lengthwise)to someone. I am beginning with the turning square I described (1.375 x 1.375 x 15) and then trying to cut (like turning on a lathe) the whole piece (a mated assembly) into a cone by removing the outside using:
1) an extruded cut with a draft angle sketched on the top view (small end) but got a hole (the right geometry in reverse) where I wanted a positive. I din't notice the "flip side to cut" option (extruded cut dialogue box) however when I tried it both pieces of the assembly were cut, (now a postive image) but the square corners of the bottom half (sketch was on the top half) were not removed but undercut most of the way to the bottom AND I was unable to perform the operation twice on each end for a complete image.
2) I also tried a rotated cut - estblished a center plane and on it sketched a profile for a rotated cut but the result was negative (a hole), as above. There is no "flip side to cut" toggle on this feature.
3) Now I am wondering if I'm in the wrong vein. Possibly I should let the assembly become the negative image of the cut and put the joint in the mold base. The solution would be in the moldbase file instead of the assembly file but, who cares. I then use the moldbase solution in another assembly?
Thanks for the feedback...a little something to get my juices flowing. Still interested in suggestions/thoughts on this question.
Thanks Again,
HA Bruce

If you use a rotated cut and sketch the material you want to remove rather than what you want the pool cue to look like then it would do what you want.

Make sure that you make the top part of the sketch higher than the rectangle that you are cutting from as you will be drawing the shape on the plane. Otherwise when the sketch rotates to form the cut it will miss the corners.

I would suggest that you want to make the sketch 0.2825 higher than your 1.375/2 dimension.

Scoobystu, just out of curiosity, why 0.2825?

I don't work in inches I am a metric kinda guy.

By the way I tried this and it works but you don't have to make the sketch any bigger after all.
