    Looking for correct weld symbology

    @kingnero, thanks for the affirmation on that. @gtaw, yep! I worked in bodyweld at Toyota for a few years, so I'm very familiar with how things should be done, or are normally done. Spent some quality time teaching weld robots. I also worked in the greater Detroit area myself for many years...

    Looking for correct weld symbology

    Thank you Al, that's the simple answer I was looking for (and what I suspected was the case). Yep, we've seen the issues that can happen with buckling, but that has been addressed with thicker sheet metal in areas, and adjusting weld locations, etc. Of course spot welding would make the most...

    Looking for correct weld symbology

    @Tmoose: Yes, the sheet metal is notched (either slot or half-round) to identify weld locations. @capntom62: To your point, it seems like a lap joint, but wouldn't that still require a fillet-weld symbol? This pic may help show with more clarity. The intended weld location notches are...

    Looking for correct weld symbology

    Yes, pretty much as you describe, half plug & half slot. It's a fillet weld in the same manner that a tsunami is a gentle wave, but that's primarily what I have been using. I'm also using spot weld, but that jury is still out (per my 2nd question). Seems like I might need to develop some custom...

    Looking for correct weld symbology

    I have a sheet metal welding requirement that does not seem to fit neatly into any of the standard weld type callouts. Typically, the sheet metal being welded together is 16ga. (.060") thick. I've used the fillet weld symbol in the past as a more-or-less generic weld symbol, but obviously this...

    Draftsight 2019 - no longer Free

    I tried both TurboCAD and QCAD (bought them both), but I just can't get used to the UI of either one. My age use of AutoCAD since R12 seems to have permanently programmed my brain to how a 2D CAD program is supposed to work. I'm surprised to not see any mention of ProgeCAD here. It's not free...

    Short timing belt - fixed motor or adjustable?

    Actually it's not a big deal, as these are going to be laser cut, so basically the only effort is in the design. It's more about the quality of the final assembly. I felt that if I didn't have to slot the motor mounts (tensioning idlers are not an option), that the belts would be tensioned...

    Short timing belt - fixed motor or adjustable?

    @Compositepro No, I currently have adjustability (see pic attached to first post), but my question was related to my replacement plates I'm going to have made. I was questioning the need to have adjustability, based on using such short belts that, quit honestly, will probably never stretch to...

    Short timing belt - fixed motor or adjustable?

    Yes, in this case it's bidirectional, and I understand what you're saying. In this case, while not as technically "elegant" as an adjustable idler pulley, I think the adjustment slots allowing motor movement for tensioning will be more feasible than the extra components required by an idler...

    Short timing belt - fixed motor or adjustable?

    Repeatability and accuracy have not been a problem thus far on previous plates I've had laser cut. But you do bring up a good point about the ability to do precision adjustment. I was mostly wondering what the 'norm' is for such an application, in the realm of machine design.

    Short timing belt - fixed motor or adjustable?

    Not really, initial installation is easy to accomplish by merely installing the bolts after the belt is in place or by installing 2 bolts loose and tipping the motor. Either way, installation is not part of the concern.

    Short timing belt - fixed motor or adjustable?

    Hello Engineering community, I'm in the process of doing some major modifications to my X-Carve CNC router. I've already converted it to ACME screw drive, and am about to upgrade once again to linear rails. My question is this: When designing for my timing belt that drives the screws, is it...

    Color assignment by object type

    I only mildly dabbled in lisp, never actually programmed anything myself. But I did appreciate the value of good lisp routines, and had a decent library of them. I was always big into custom menus & pgp file customization for quick command access. That was back in AutoCAD 12 days. Funny story...

    Lol, I see what you did there.

    Thank you maripali, I will give this a go!

    Color assignment by object type

    The draftsmen are responsible for the DXF creation from the model, so hence the clean-up is our responsibility, of which splines are occasionally a part of. It's true that there are only a very few mouse clicks after opening the geometry, to identify the splines via. color change. My goal was...

    Color assignment by object type

    Interesting idea, never really considered that, but I see how it would be possible.

    Color assignment by object type

    Yes, that's exactly how it's handled now.

    Color assignment by object type

    Thank you guys, I appreciate the input! Currently, our models are done in Inventor, then the DXF files are processed or "cleaned-up" in AutoCAD. Splines don't occur terribly often, but as you mentioned SparWeb, it's when a bend crosses a radii. I am not particularly fond of replacing a spline...
