    CATIA Frame

    Nope, can't get it to work. It keeps saying it couldn't find the directory for my Part file. I have called the local Dassault Systemes office in Gothenburg but they were not able to give me the answers. Only told me to check out the help files and the companion. I'll have to see if I can get...

    CATIA Frame

    Hi Fernando, I don't think that's relevant with the structural design profile issue I'm having. Thanks for your time anyways. About the issue: I found where it says I have to resolve the parts, but I don't know how to do it. online/CATIAfr_C2/sr1ugCATIAfrs.htm In the help files there it...

    CATIA Frame

    I've tried that before and I've tried editing the catalog on that AISC folder as well as the catalog in the StructuralCatalogs folder. Didn't work. I did notice that the profile sketches in the ModelsResolved folder match up with the profiles listed in the Shape tool menu, where as the design...

    CATIA Frame

    Hello, I'm still having zero luck with getting custom profiles to work for my v5R19. I see that there are no more replies and am just hoping there might be some tips after this bump. Regards, Horace Lai

    CATIA Frame

    I finally got around to installing the online help files. I look over it and was able to create catalogs. I was also able to create a tubing profile using sketcher. But I can't apply any of this to the shape tool in the structural workbench. I have no idea where the catalog for the shape...

    Hi Azrael, Thanks for the tip, it helped a lot. Would you know how I could create custom pipe sections? Thanks again, Horace

    Analysis of Carbon Fiber Parts

    Hello everyone, Can I get some advice on analyzing carbon fiber parts? How would you model the anisotropic behavior of such material? How would you model the properties of a certain weave pattern over another? Also, what FEA program would you use to do this sort of analysis? Thank you very...

    CATIA Frame

    Azrael - "do you mean that you define the tubing dimension in a weldment feature?" Yes, that's exactly it I can't find any good tutorials on the Structure Design workbench. I have both the Structure Design and Weld Design workbench. Right now I have a wireframe model that was made using the...

    CATIA Frame

    Hi, I'm so-so new to CATIA in the sense that I've went through tutorials in a book but never applied the software into a project. I need to draw a spaceframe in CATIA. When I was using Solidworks, I drew lines for where the steel tubing would go and then use the Weldments feature to apply a...

    Designing a Motorcycle Rear Fork/Swingarm

    The biggest deflection on the motorcycle chassis is the head tube, the tube that holds the steering fork. This would change the steering alignment quite a lot. The chassis I'm designing is almost identical to the Norton Featherbed chassis due to packaging concerns. It was not surprising to...

    Designing a Motorcycle Rear Fork/Swingarm

    Using the 5g bump assumption and including the weight of driver, passenger, and cargo, I have made some tests on the twist, bump/compression of the swing arm and chassis. For the swing arm, I had deformation of about 1/16" max but i don't think that matters too much. I think what matters more...

    Designing a Motorcycle Rear Fork/Swingarm

    Hello everyone, I'm in the process of designing a swingarm for a 250 pound motorcycle. The kind of a swingarm is the traditional types found on cruisers. Wikipedia calls it: Swinging fork - the original version consisting of a pair of parallel pipes holding the rear axle at one end and...
