Re: Springs and Plastic Deformation

Finer mesh: Check. Contact points: Check. Plot linearized stress: Fail. When i try to set up a clip filter along a line, i select two points and get: Coin warning in SbVec3f::setValue(): The double precision vector will not fit into a single precision vector. *** Abort *** an exception was raised, b...

Re: Springs and Plastic Deformation

Awesome! This is very much a work in (early) progress. All files available on: https://github.com/maidenone/OpenBiped its dependent on my solidpython fork (generates scad files and BOM with total cost and print time) https://github.com/maidenone/SolidPython I have a freecad design of the same spring...

Springs and Plastic Deformation

I am trying to make a script to auto-generate 3d printable "springs/dampener" that can handle a given load. It was a few years since i studied material physics.. so now i would appreciate some input on how i can calculate or see when or where the part should "brake" or become per...

Circular dependencies, How to break a part.

Note: this is for latest build (git) of 0.17 I have found how i can introduce circular dependencies. 1. create a pad (will be named pad), 2. from a sketch based on a wall on pad, create pad001. 3. create pad002 from the face of pad001 so you end up with a "U" shape. 4. create pocket001 tha...

Re: feature req: additionally reference cube and cylinder at their midpoints

also, almost related, i want to be able to select a middle point on lines ^_^, abuse this a lot in solid works. one day i will write a python script that inserts a point in the middle of the selected line. The hard part will probably be to have it automatically update its position when the line that...

Re: Editing early sketches not effecting part

Also got the same issue when editing old sketches, almost always fails, so removes all pads and start padding again from start each time i have to go back. if i where smart i would base all sketches on planes instead, but i am to lazy to be efficient.. My circular dependency got more paths then your...

Re: URDF Workbench, robotics

Not at all, quite dead for the moment, am afraid, did not come that far. I will probably pick it up a bit later again. Right now i am playing around with very simple robots in ROS/Rviz/Gazebo, will probably revisit this later on when i start playing around with more complex robots.

Part Design/Sketcher issues latest build (git)

When i go into part design, create a part, body and then create a sketch, x,y plane, then the sketch will be invisible in edit mode. when i exit edit mode the sketch will be visible again. have also tried to open an old file with ...
