    Macro: Retrieving custom props from Part while in a Drawing?

    I have a macro which I pieced together from another one found on the web. It saves a drawing as a pdf and names the file with a concatenated list of properties. My problem is that the properties I want it to look at are in the part file, not the drawing, and I don't know how to get the macro to...

    Trying to write a macro to re-order sheets of a drawing...code inside

    I'm new to VBA and this macro-writing business, but here is my attempt. This macro: -inserts a sheet, naming it with the correct number (it does not get called sheetcount + 1 because we want to disregard one of the sheets when numbering them) -Deletes a particular template note on inserted...

    Tangency problems in Wankel motor model assembly

    I'm an Industrial Design Technology / Technical Graphics major currently taking my 2nd Solidworks class. I don't usually get stumped all that easy but the project I've chosen for my midterm is giving me problems. I'm making a model of a wankel motor (like in the RX7) and am having troubles...

    Creating perception of integrity in auto unibody...DIY methods?

    I posted this in the vibration/acoustics forum as well. I hope that's ok. It seems like with each new model of car it is claimed to be some measure (30-40%) "stiffer" than the previous generation, laterally or longitudinally. For some cars, there are aftermarket parts to increase...

    Creating perception of integrity in auto unibody...DIY methods?

    It seems like with each new model of car it is claimed to be some measure (30-40%) "stiffer" than the previous generation, laterally or longitudinally. For some cars, there are aftermarket parts to increase stiffness of the unibody, such as subframe braces and strut/shock tower bars...

    Modern equivellant of continuously variable McCulloch supercharger?

    I found this website a couple years ago: http://www.vs57.com/ It's dedicated to the old McCulloch superchargers that were on Kaisers, Packards, and Studebakers, among others. I'm particularly fascinated by the CV pulley system, which works on the same principle as CV transmissions (like on the...

    Formula for peak piston acceleration at top/bottom of stroke?

    I found the formula for mean piston speed on this forum, and that was useful. But I want to be able to figure out how much more stress I'm putting on a piston (due to rapid change in acceleration) if I shorten the rods. I remember a formula from Physics class: Final velocity =(Initial...

    Any info on lean burn & swirl (in combustion)?

    I'm interested in finding more info on these concepts. I know about Larry Widmer and read everything he says on his Endyn board, but I'm wondering if there are any books or other experts in this area I might be directed to... thanks
