I have tried 2 calculation methods from Roark, 1 for ends which are restrained in both torsion and warping and the other for ends free to warp but torsionally restrained. The answers I get suggest twist at the centre will be approx 3 degrees and 9 degrees depending on the case. The ends are...

Thanks all for the replies. I'm going to check Roark first and see what comes of that. As someone who knows little about FEA would it be right to assume a situation like this would be ideally suited to the FE method?. I've started researching the FE method in past few months with view to...

I am trying to find the angle of twist of a thin walled open form cold rolled steel section. The application is a roof member torsionally restrained at either end and subject to a uniformly distributed torque. I have section properties including Torsion Coefficient (J), Warping Coefficient (Cw)...

I am looking for a system of seam joining 2 layers of Mild Steel(each layer 1mm thick). Currently this is done with a "Tox" portable clincher but as the length of the joint is 6 metres, (18 feet approx)and the machine only does one clinch at a time, the time involved is excessive. For various...

Interesting point beachcomber, and I am worried my new role will involve creating and assembling lots of parts simply to have edges that can then be used in derived 3D sketches. May have to look at additional modules for SE David

Theres plenty for me to investigate so thanks all for your help David

Thanks for that Fred, I have the option to upgrade and I will examine the options you have outlined. The derived curve option sugests a curve derived from edges etc. of existing parts, sketches etc., I am hoping there is an option that allows me draw using x, y and z coordinates simultaneously...

Dear all, My new employer uses SE, I'm an experienced Solidworks user. Much of the work I will be doing in my new role is similiar to what I've accomplished in SWX using the 3D Sketching functionality (complex sweeps etc.). I've been looing through an academic version (V12) of SolidEdge and...

Thanks for that smcadman, will examine what you have suggested.

Thanks for that ctopher, I'm wondering how does everyone else using folders deal with the problem of data input if there is no appropriate software. I assumed our setup where I work was grossly lagging behind everyone else but maybe its not, either way there has got to be a more efficient way of...

Thanks for the reply CorBlimeyLimey. Nothing here that quite matches what I am looking for. I was thinking that if I could get a typical example of an NC file for a folding machine then maybe it might be viable to have a custom application develped assuming nothing else is available. Does anyone...

My employer manufactures folded sheet metal products for the roofing and cladding industry. The material is typically less than 2mm (1/16") thick mild steel and product lengths are 8mtrs max. The pressings are simple 2D profiles and high levels of accuracy is not critical. At the mment all...

Another option you may wish to explore is "Solid Converter PDF", you can download a trial version from the Net. It is very good once you have played around with it for a while to become familiar with the various settings, also very reasonably priced. You csn then save the modified file back as...

Once again many thanks to all for your contributions, I will take some time to consider the options. Thanks zekeman for your advice re posting questions, I will make a better attempt if I need to post the same query again. Bengy2

Tim, For what its worth try "TrueGear" an Autolisp routine which you might find useful. You can download it from the net. David Leech

Thanks for the reply TXS. Having checked out your website your views carry considerable weight given the type of products you develop. Having only recently being exposed to ProE (after using Solidworks for years)it appears that considerable improvement is required on the quality of the...

I am trying to decide on a rendering pakage to learn and am wondering if any comparisons exist between any of the above or other rendering packages which might help in deciding on which option is best. The models wil probably be native ProE but can be exported if necessary. I am looking for ease...

I have been receiving the message below in Assembly mode "Invalid reference to segment object used" with the message title "Update Component". Can anyone tell me what this means and what to do to get around it as there is nothing I can do in the assembly without this message appearing.

Can anyone tell me what the message "Invalid References to assembly object" means. I have started getting this in an assembly when I try to carry out any function at all. I have had this before and I had to rebuild the entire assembly from start.

Can anyone suggest a modification to the Scotch Yoke Mechanism which will produce a uniform rate of motion of the reciprocating slider as the crank rotates. A standard Scotch Yoke does not produce a uniform movement.
