    Self-intersecting sweep doesn't form valid solid body

    Hi, I'm trying to model a retainer for a USB port cover. Think of the thing that retains your gas cap. It's a combination of an o-ring to do sealing, and a string that tucks down inside the housing of the part. I have a sweep that goes around sharp bends and the cross section self-intersects...

    Let's burn more sunshine

    Climate change deniers, go away. So let's say global warming is caused by pulling tightly-packed carbon out of the ground in solid/liquid form, then combining it with oxygen and creating more CO2 than there was previously. Let's also say we want to simply freeze the amount of CO2 in the...

    Intermittent wheel wobble

    If I'm misusing this forum, please let me know. I have a 2001 Acura TL. I had warped rotors, so I replaced pads and rotors, then rotated the tires myself. I found there was a vibration that got worse with speed, so I figured an out-of-balance wheel. I asked a local shop to balance the wheels...

    I took a new job a little while ago. I thought I would be taking them into new areas but they need me to do a lot of CAD, which I'm not very good at. I might build enough new stuff so I can stop doing CAD, but that might be a couple years away. I feel like there was a miscommunication and we're...

    L-shaped 6-bar linkage motion

    I'm trying to open an access panel, but the packaging is very tight. I need to move sideways about 2 inches, then upward about 18 inches. The initial motion has to be very horizontal so that tends to rule out 4 bar linkages like on bus luggage doors. Also, I can't go sideways more than 6...
