3D rib construction for sweep

[BlindChickenRacing]

I am running SW2001 and am trying to create a rib on the XY that is duplicated on the Z with connections between so I can do a sweep of the entire thing. I am trying to create a representation of a part made of steel tubing. Is this possible and if so how?

The problem I think I am having is creating or defining the location of the planes to draw on. How do you define a custom plane to locate a line or drawing segment in a 3D part?

Not at all sure what you are trying to describe, and from the lack of response, I assume no-one else knows either. Usually several people will jump on these types of problems real quick. How about a simpler explanation in layman terms?

Suggestions:
The term "rib" has specific meaning in SW (including 2001 ,if I remember correctly) so use care when using it - people make assumptions.....

..on the XY (?) duplicated on the Z (?) with connections... to do a sweep (?) to make a tube(?)

I'm thinking he's making a (solid) rib then a pattern of them then filling in between - nope, 20001 does not have multibodies - anyway then he wants to sweep a solid!!? nope, must be some sort of sketches on perpendicular planes?.... and he wants to somehow form it all into a hollow tube?......

See my confusion? Would love to help, but don't understand the problem.

OK. Picture the framework of a garage. I am trying to create a cad drawing for a carport made of square tubing. The idea is to create one rib that is essentially a U shaped piece on the XY that is then duplicated every four feet on the Z. Then connect each rib to the next with 4' tubes.

The question I suppose is how to duplicate items that were created on the XY plate on planes with a different depth.

The other being how to create a 3D drawing of a framework that I could then do a sweep of to create the tubing.

JNR is correct, "rib" has a specific definition in the SW community, and it was throwing me off. Let's use the term "support beam".

Look in SW Help, look for Sweep, Component Pattern and Linear Pattern. These are probably going to be the 3 functions you will need to create this garage of yours.

You will also have to decide if you are going to create this as a single Part model, or as an Assembly.

Shouldn't you use the assembly mode?

I think it's better firts create the parts. I gess they will be one U shaped part and 2 tubes (1 vertical; 1 horizontal).

Then put alltogether in an assembly where the U shaped part will be "patternized"

I think MacPT hit the nail of the head. You seem to be trying to make what is really an ASSEMBLY using a PART file. BIG DIFFFERENCE. Solid modelling systems replicate the real world pretty closely. You are building electronic models of parts that are almost as real as the real thing. you are not duplicating the traditional drawingboard method of designing the whole thing in a layout. Think about the real world situation and duplicate it in the CAD system. You will have posts (maybe 4 to 8 of them all identical) plus beams conecting the tops of the post (maybe two lengths - side and ends). Then you will have joists (maybe 10 or more all the same), also sheets of say corrogated plastic roofing. So now you have four PART files (more on that in a minute) and one ASSEMBLY using multiple instances of them. (And guess what, you can now make lots of assemblies of different sizes of carport using the same few part files real quick.)

Once you have got the hang of this concept, move on to looking at component patterns where applicable in the assembly. Then part file configurations to perhaps reduce the number of PART files, while having beams of similar shape but different dimensions. Then look a configurations of the assembly for multiple carport sizes.
