    mechanica - is it possible to "view max"with "capping surface&quo

    I am running Pro/MECHANICA on a complex part with some internal areas that are difficult to view. I can create a "capping surface" or a "cutting surface" to view these regions, but then I an unable to use "view max". I know you can zoom in on a particular location...

    plastic latch

    I designed a similar part a couple years ago. Polypropylene is your best material for a living hinge, although I have heard of people using polyethylene and nylon. Try GE plastics. You will need to register and get a password. Here is their design guide for living hinges...

    looking for hex-shaped steel tube

    TVP, I'm not sure what you mean by the "~ 0.1 to 1 m section". The inside of the section should measure 1.125 inches (flat to flat). I don't care about the outside dimension (wall thickness), as long as the wall is thick enough to withstand a little torque. Also, wouldn't it be...

    looking for hex-shaped steel tube

    I need some help. I am looking for a hex-shaped steel tube to make a nut-driver type tool for a 3/4" nut. The hex will need to measure 1.125" on the inside. I haven't been able to find anything except squares and rectangles. Does anyone know a source for hex shaped tubes?

    threaded inserts and residual stress in Polycarbonate

    Thanks, Soupcat PSM recommends a hole size of 0.157" +.004". the hole is 4mm or 0.15748", plus draft. So if anything, the hole would be probably slightly too large, but I don't think it's too small.

    Pro/E 2001 crashes when using MODIFY command

    I am having a problem since upgrading to 2001. Sometimes when using the MODIFY command in Part mode, Pro/E will crash and just disappear completely. It happens after selecting a dimension value to modify, typing in the new dimension, and clicking OK or hitting ENTER. Has anyone else had this...

    threaded inserts and residual stress in Polycarbonate

    Thanks everybody for your advice! Actually I was incorrect when I said that the insert was ultrasonically inserted. It is thermally inserted. CoryPad, we are actually getting the inserts from PSM. Thanks. Patprimmer, you are right, there is a much thicker wall section around the insert...

    deleting multiple items in drawing mode - Pro/E 2001

    Never mind!! I just figured it out. I am such a jackass. There is a button you can put on the toolbar "delete many objects". I have been struggling with this for an hour.

    deleting multiple items in drawing mode - Pro/E 2001

    We have recently switched from Pro/E 2000i² to 2001. In drawing mode, the menus are different. I can't figure out how to select multiple entities so I can delete them at the same time. I know I can hold down "shift" and select them one by one, but that takes too long. I want to be...

    bimetal design guide

    I am working on a product that has a bimetallic strip that is used for temperature compensation. It is a U-shaped strip, with the "legs" of unequal length. I am attempting to calculate deflection, etc., but don't know where to start - it is more complicated than the cantilever beam...

    polychloroprene for butterfly valves

    Neoprene (chloroprene) has the following chemical compatibilities (from Apple Rubber catalog): Kerosene Questionable Methyl Ether Questionable Diesel Unknown Petrol Poor Jet Fuel Poor So Neoprene (chloroprene) sounds like a poor choice for your application. Can...

    threaded inserts and residual stress in Polycarbonate

    I have a polycarbonate part with threaded inserts (brass inserts, 4-40 thread, ultrasonically inserted into PC about 7mm or 1/4" thick). I am having a problem with cracks appearing around the inserts. Some of the parts appear to have some shrinkage or voids that occur due to the thicker...
