    Interpretation of General Profile Tolerance Note

    If the MBD model has no datums, it's not completely defined.

    Aluminum Angle Rolling

    I read your post 4 times, it's not clear what you want. You want to make an angle from sheetmetal? I'm not sure why you would roll an extrusion to make a radius.

    Position Control on Circular Face

    How is the pos tol measured to the thread?

    Twin screw extruder modelling

    Depends on your CAD software. In SolidWorks, there are probably a few ways: Different solid bodies merged with threads; Swept boss; Lofted cut, etc.

    Thread Failure in Aluminum Casting

    I would also try the insert. Also, make sure the tapped threads are clean. I have seen too many threads with metal bits in them from the tapping process that will cause the bolt to strip or get stuck.

    Voyager I is trying phone home once again...

    I think it's amazing how NASA can still read those signals.

    Recommanded tolerance for datum features

    I have seen young engineers switch careers, burn out, change from mech to other engineering, because they are taught GD&T and how to tolerance parts. They want to only design a 3D model and move on. The ones I find that stick with it are the ones that are taught machining practices, they get...

    Detail View - solid line vs phantom? What is standard?

    It should be a thicker phantom line. In SolidWorks, it can be set in the drawing templates so it's always there.

    Total Runout - Long Shaft

    When machined in-house or from a vendor, can the straightness be held to the tolerance you call out?

    Straightness of a bend on sheet metal parts

    No. I only remember that we did that process.

    Straightness of a bend on sheet metal parts

    I only had to do this once several years ago. We made a fixture from tool steel, sandwiched the sheetmetal with it, stressed relieved in oven. I don't remember temp/time.

    Design of Threaded Insert

    I agree with 3DDave. Use an existing insert. Would be an expensive part to design yourself.

    Looking for Simple 3D Wireframe Drafting Software for EDM Tool Paths

    If SolidWorks or something similar to complex, then anything may be too complex. A lot of small startups use Sketchup. https://www.sketchup.com/en/plans-and-pricing/sketchup-free?srsltid=AfmBOopW6jr78dsLI8d90N5FzWScmAWp8dJrvc4xbBUGSnULvY6UYicu

    Standards on filling holes with weld

    Can you tap the holes, make threaded inserts, then weld in place? Chris, CSWP SolidWorks ctophers home

    STEP file conversion

    How big? If just working virtual for your company use, maybe try pack and go zip? Chris, CSWP SolidWorks ctophers home

    Question about controlling bow on extruded profile

    Curious how will you measure the bow? Chris, CSWP SolidWorks ctophers home

    Solidworks 2024 minimising on opening files

    I have never seen that. Must be a Windows setting. Does this help? Link Chris, CSWP SolidWorks ctophers home

    Unknown Item

    I agree with John. It has 3-axis adjustment, probably for something optics? Residential or commercial basement? Chris, CSWP SolidWorks ctophers home
