Hey All,
I have a formed sheet metal part similar to that shown. Dataum A is the flat back surface, Datum B is defined by a hole perpendicular to A. Datum C is defined as the center plane of a slot. I want the ears of the sheet metal part to by symmetric to a center plane running through the...
Hey All. Not sure what category this should go in, so I'd start here.
I'm working on an investment cast stainless marine product. I'm not that familiar with investment casting. It seems to me that no draft is required on the investment cast itself due to the ceramic mold being broken or...
Hi All,
I have a project where I am designing a new fastener head. It's something similar to a Philips head or Pozidrive type head. I've looked at the ASME standard for fastener heads, but they only give a few dimensions on the head and drive recess geometry. For instance, I've found additional...
Hi All,
I posted this question months ago and I guess I either forgot the answer or moved on to other things and never figured it out.
I'm trying to figure out how to drag the control polygon for a simple two point spline that is constrained by tangency at both end. I do this all the time in...
Hi All,
I'm working on a quote for a client of mine that wants an engineering certification for a lightweight hanging frame. This frame is constructed out of EMT: the electrical conduit that you run wires through. There is no standard for EMT material properties as its typically not used...
Hey All,
I don't know whats up, but its driving me nuts. When I create a spline curve tangent to construction lines at both ends, I can't seem to modify the spline curvature. It has always been the case that you just right click on the spline, hit modify, then click the tab with the spline...
Hi All,
I'm designing an electrical connector housing that is to be machined from brass. I need to design in a ramping bayonette-style twist lock into this housing...like what you would find on a typical BNC cable connector. This particular design requires that a piece of the brass flex like a...
Howdy,
I'm looking for any equations to help ballpark a spiral spring design. I'm working on a retractable lanyard for keys / tools, etc. I'd like to find some equations that will estimate pull force for a given mat'l thickness, O.D., I.D. etc. This is the same type of spring you would find in...
Hey all,
I'm coming back to Pro/E after much SolidWorks work. I'm trying to use simplified representations similar to the way that configurations are used in SolidWorks. The problem is that these representations don't seem to save with my top level assembly. It always shows the generic...
Hey all,
I was wondering what using actual skeleton parts in an assembly gives you over just using an additional part file. I ask because I have the basic version of Pro and was considering the AAX extension. I used to run it at a past job, but can't seem to figure out what I'm now missing out...
Hi All,
I'm looking for some recommendations for a moldable rubber material to be used for a handle on a swimming pool toy. It has to be good in chlorinated water, sun, and pretty durable. Also, the current material gets all dirty and sticky with use...anything out there guard against that? I...
Hey all,
I'm running an analysis on a welded bent sheet metal assembly. Simulation treats these as shells. I've had the best luck creating my own surfaces and then applying a thickness to them in simulation, but I'm not sure which direction Solidworks is deciding to create the shell. This can...
Howdy Y'all,
I'm wondering if basic beam theory still applies to x-sections that are not-symmetric across their centerlines. Say, like a c-channel on its side or a right angle bracket. It seems to me that if the load is not going through the centroid of the x-section it will induce a twisting...
Hi all, just looking for an opinion.
I've been approached by a client asking for FEA work on an elevator system that needs to be approved by a PE. The analysis deals with the loading and structure of the elevator system, not surrounding building structure.
I have my certification in Mechanical...
