I want to know how to model this cab with pro/e.Do any body can give me advice?What I want to know is how to stick the beams to the steek cover so precisely or perfectly?I'm very appreciate that somebody could tell me the process to do that? Below is the picture of the cab:   Modified by edison1982 at Sun, Nov 26, 2006, 04:57:38

hello, You can model this CAB easily using combined solid and surface options or otherwise you can model using sheet metal module. but it will be littlebit tougher than earlier one. Enjoy

Hi, Are you currently a ProE user? I used ProE before, and there are a lot more other CAD softwares that are capable of doing this. Such as SolidWorks, Solidedge, Onespace Designer, which might be cheaper Are you going to come out with the 3D modeling from the photo/picture? That are a lot of work to be done and you need an experienced mechanical design who is experienced in the 3D software as well. Before you open up your 3D software you might need to first come out with a plan. You need to know the cab's outline dimension, bills of materials, positioning and space allocation for each component. Then only you can start to open up your software, and slowly start to come out with the design in CAD. Ofcourse, in CAD everything is perfectly accurate, no manufacturing tolerance. For example, you design a steel bar which is 250mm long, so you just plug in the number of 250, and you can change the number anytime you want. Hope it helps rgds, patrick

vijayguru,thank you for your advice! I can model a cab like that,but i can not model it so precise.My method is model a cover first and then using offset surface to cut every beam respectively.But i think it is very boring to do that,and i also think it is exactly not a good methods to do that .The second method i used is makeing the cover first and then makeing some datum planes.Then use these planes to intersect with the cover to make some curves.The curve is stick on the cover.You know,then I use these curves to sweep the beams, but it's not so precisely, I mean there are always some beam extending outside of the cab cover.Could you give me some more advice?Thank you for help!

Normally, when we design and engineer an assembly, the CAD modeling supports the engineering drawing requirements. The engineering drawing requirements are determined by the fabrication/manufacturing requirements or sequence. The two primary approaches to design and modeling are the bottom up design method, which is taking all of the required parts and designing them together. Then there is the top down approach, where the final assembly is known or the envelope and the individual parts are designed and fit back into the assembly or envelope. Regardless of your approach, you will need to organize your cad models in a manner that is manageable. Since you seem to already know what the assembly is, then I would design the cad model in subassemblies. If the frame is a weldment, then model the frame as one cad model (inseparable assembly). The sheet metal and other parts are likely to be separate parts, so you can create a separate cad file and import all into the designated top assembly cad file. I am not a expert with Proe, however I do have at least twenty thousand hours on other systems (Solid Edge, Intergraph EMS, CADAM, ,Catia, and Microstation). All 3D Cad Packages have means or command functions to associate individual parts or subassembly files together. I would assume Proe has coaxial, planar, tangent, and other parametric constraints available in assembly mode to orient the your parts and assemblies together. Additionally, many cad systems allow you to just anchor the part or subassembly within the model and manually move to the final assembly position. In general, when you model your parts and assemblies you will model them as though they where perfect. Your engineering drawing (blueprint) will include the requisite manufacturing tolerances for the real world. Sometimes when a part has a bunch of plating or other surface treatment or coatings, we model our part at the pre-coatings size and then offset the part within our CAD model This can also happen when we know there is a bond line of some predicted thickness within a assembly.

Thank you ,Kelly!I have found an article about this topic just now.That is exactly what you said.In proe,there is a assemble skeleton to do that:what you said top-down.You make a skeleton first and if you change the skeleton,then all the parts change too.I think your idea is excellent.Thank you for help.
