How do you create 3d model of one or both from 2d to 3d, or do you have go 3d only? Any help you be grand! :-)
Also, I'm not looking for the complete step into rendering. Just wire-framing finish.

I attached examples


Thank you in advance

I would draw the rings and posts as polylines
then extrude smaller circles along them as paths
When all done one could then union them together or make a block

for the tomato cage DONUTS would also work


sad, autodesk hasn't given us the 'lattice' tool from MAX as yet.

this from 1 cylinder and four sweeps

The wire basket would be about the same

The  tomato cage looks like it is incorrectly modelled.
The vertical legs should be either inside or outside the rings.
The legs can butt underneath the upper ring, but shouldn't coincide with the lower rings.

The alignment of components will actually depend on the method of assembly chosen by the manufacturer.

Drawing the cage in 3D should only take a couple of minutes.

The basket shouldn't take long either, there are only 5 pieces to extrude and copy.

To my knowledge there is no program to convert 2D to 3D for this type of work.

added:
Is the basket you show meant to be stackable ??

Kerry,
 I noticed that the cage was wrong, that is why I did mine that way.


That small basket doesn't look stackable, the sides appear to be far too vertical.

You guys are awfully rough on a guys 1st post, I'm guessing he found those images somewhere else.

I don't see what I said as 'rough'
... anyway, Why would I want to call bricks icecream ??

nestable basket

the tricky part is the dimensions of the 2d elements to get the 3d components correct
there is a 3 degree slant to all four sides that's how I know it will stack one into another

welcome deadjam82 excellent question

for some things it is a good idea to actually know how the thing is made
to be able to model the thing at all

most of a time a basic pencil sketch is enough to understand what you need to do

others the limits of your knowledge or the limits of autocad 3d modelling tools will force you to improvise

I would put the uprights of the tomato cage _inside_ the rings,  if the uprights area on the outside, then only the weld is available to resist breaking, and it won't.

I think you have crossed over from

How is it modelled?


Into the land of


How is it made?

Although it does help to know how a thing is made to model it most correctly.

Not really
As we observed earlier, the "tomato" cage has been modelled in a manner that is inconsistent with how the thing is actually made (manufactured).

sort of like the difference between how Barbie is modelled, and how real women are made.
