    Clash Check

    Is it possible to tell catia to ignore parts in a clash check or at least be able to exclude certain clashes from a report? I'm thinking of fasteners, inserts that sort of part which are thrown up as clashes but are not "real" clashes.

    Independent Checker

    It has been said to me that my original post was vague and difficult to see through and for that I apologise. Some additional information that I hope doesn't muddy the waters more but will add context to my question. EASA: European Aviation Safety Agency. The European Union authority in...

    Independent Checker

    The approval process to be an authorized checker where I work asks "what does it mean to be an Independent Checker". This has me foxed at the moment. Anyone enlighten me? It's relative to the signatory process under the DOA awarded to the company by EASA.

    XML clash report

    Hi, When I run a clash analysis and save the results as an XML file the report contains all the lines I have marked as irrelavent. As I'm only interested in the relevant clashes I would like to exclude the others from the report. How can I do this? Regards, John Wills

    Reusing design features

    Using Catia V5 I regularly create designs that incorporate components in a product requiring a repeatable set of features in an interfacing component. I thought of using power copies to accommodate this but the power copies would be pretty complex: some having several pockets & holes and others...

    Ladder Chassis Analysis

    For a project I want to learn how to analyse the torsional and longitudinal stiffness and strength of a ladder chassis as used in the AC Cobra in the 1960's. I want to use a simplified model and techniques as this is akin to a conceptual design study. Can anyone help or point out any relevant...

    ladder frame torsion FEA

    I've managed to apply the case I wanted by adding small pads to the inside surfaces of the frame longitudinals and adding restraints to them. the following image shows that my analysis indicates zero deflection of the frame along the longitudinal and transverse axes through the c of g. I'm...

    ladder frame torsion FEA

    Thanks for the reply it was very informative. I'm quite experienced with v5, but new to the GSD function . I have run 2 cases. The first was clamping the end faces on one end and the other where I clamped diagonally opposite faces. Neither quite give me what I want as the clamped ends show zero...

    ladder frame torsion FEA

    Using generative structural analysis I'm trying to set up a pure torsion case for a ladder frame as shown in the attached image. I think I need to restrain the part somehow, but everything I try fails.

    Book Recommendation

    I've not looked at many books on catia, having learned on courses and on the job, but I think the SDC publications series look quite good. I get my student son to borrow them from the university library! I'm currently working through the FEA tutorials book. Interesting, but I don't think English...
