Split Taperd Column

Recommended Posts

I'm having trouble creating a half tapered column. I managed to create a split rectangle column but can't to seem to figure out the best approach to do the same for a tapered column. Has anyone else accomplished this task?

No, he wants half tapered column.

Use a 2d molding (molding shape drawn in elevation), that is one way.... if I wanted, I could probably come up with at 3 more ways to do it........ Boolean operation. (Yech), Or use a full column and by redefining the "plane" (I forget the correct terminology) Location, it can be resized. (Not perfect), hmmmmmm...... not sure if I can think of a fourth without taxing my brain........

Primitives Pyramid truncated made for the job

He is looking for a half column, am I missing something?

Draw profile of half in elevation with pline solid, move it so that the straight edge is at absolute 0, 0. Convert to solid, explode to faces, delete the faces you don't want (keep the one that is at 0,0) ; select it, revolve the object around the Z axis-180 degrees.

Glenn has a video on here somewhere-that's how I managed these.

Glenn's video can be found in this thread (which might hold some other valuable information as well)...

I could be reading the OP's request wrong, but what I think he needs to do is simply make the column as he needs it (full version) from a solid, and then make another block of primitive to cover 1/2 the column and then do a subtraction of the solid to get 1/2 the column. 

 

Here is an example of what I think you may be after....

He's a genius. I knew there was a fourth way.

I may not understand what half column is to me it has a 8" square base tappered to say a 6" square top

You already mentioned this method Scott, remember...

"...Boolean operation. (Yech)..." :)

looking in plan view, cut in half, base is 4x8 and top is 3x6.

I didn't know what a boolean operation was. I assumed it had something to do with true or false. Thanks though I appreciate it.
