    Calculating the inside volume of an assembly

    I've done something similar when I have to determine the wet weight of a pilot plant. However, rather than fighting in-context design I save the assy as a part then draw a bounding body. Then it's pretty simple to do a combine/subtract. Dan www.eltronresearch.com Dan's Blog

    Mechanical Spring Representation

    Thanks, fellas. That's what I thought. I'll just cherry pick the pertinent information from old standards for what I want to see on drawings. Why did ANSI drop the spring standard, I wonder? Dan www.eltronresearch.com Dan's Blog

    Mechanical Spring Representation

    I'm running up against a wall in specifying the standards for information that needs to be included on an engineering drawing of a spring. So I thought I'd ask the experts. I have done a search and checked the FAQs, but I haven't found anything yet. ANSI Y14.13M used to be the standard, but it...

    Who is going to SWW15? (Phoenix, AZ)

    I'm not going to make it. I really need to retire so I have more time for these things. Dan www.eltronresearch.com Dan's Blog

    Spring Expanding in Motion Analysis

    Here's the version that I was suggesting. Dan www.eltronresearch.com Dan's Bloghttp://files.engineering.com/getfile.aspx?folder=a7dd4419-2368-4272-b9a0-ccdb8d25f50a&file=Moveable_Coil_Spring_Helix.zip

    Spring Expanding in Motion Analysis

    You can still do it with the end segments being in a fixed position. Just mate a plane within that component to be parallel or coincident to the ground plane while leaving all other links in the spring free to move. Dan www.eltronresearch.com Dan's Blog

    Spring Expanding in Motion Analysis

    You can create "live" springs in several ways. I'll try to explain two. In one instance you can create a sweep of the spring profile within the context of the assembly. The path sketch of the spring should be constrained to the components that are moving relative to each other. In this instance...

    checklist or set of company standards for making models

    How about: no mustard and ketchup allowed on the Feature Manager. This one grabs me by the pink parts every time I work on someone's model that doesn't care about errors in the feature tree. Dan www.eltronresearch.com Dan's Blog

    Surface of a Sphere

    Yeah, it should be a fun one to make. Unfortunately, I can't open the '14 files. If I update to '13 sp5 I should be able to, right? Dan www.eltronresearch.com Dan's Blog

    Surface of a Sphere

    Here is the method I used. It isn't exact, and it needs some tweaking. However, I think it is passable. Dan www.eltronresearch.com Dan's Bloghttp://files.engineering.com/getfile.aspx?folder=32311c6e-2715-4574-96ef-40f4ac4b20ec&file=Sprocket_Chandelier.zip

    Surface of a Sphere

    Yes, a sphere has only one diameter. The plates that I need to attach to the surface of the sphere are differing sizes. Imagine sticking a bunch of CD's to the outside of a beach ball then deflating the beach ball. That's kind of what I'm going for, but the CD's are various diameters. As an...
