Re: Assembly3 preview

We should consider using the SolveSpace way of building assemblies. 1. create a "assembly sketch" in 2d (or 3d if you hate yourself) 2. create the "skeleton" of how your parts will move in the assembly sketch 3. constrain your solids against your skeleton. This makes it much easi...

Re: Assembly3 preview

Screenshot from 2017-12-15 16-02-48.png Now sliding works, but sometimes during "auto recompute" i get complaints about part being "fixed" while moving with "move part". Now i tried to add a joint to one end of the slider to create a "V" with the slider decid...

Re: Assembly3 preview

Can you get information about DOF between each objrct from the solver? I am working on a "RobotCreator" workbench where the user manually place links and joints and define limits and orientation for the joints. Right now it exports a SDF file that you can load in Gazebo (robot simulator). ...

Re: Assembly3 preview

As I understand it, the five "biggest" cad programs as of today seems all using the principle of breaking a product into files , each representing one fysical part, e.g. a nut. This file then becomes relatively easy to exchange with a PDM system. In stead of separate files, the limitation...

Re: FeaturePython shape, union sphere and cylinder

Now this was what i was after! Thank you! fp.Shape = Part.makeSphere(1).fuse(Part.makeCylinder(2,0.2,App.Vector(0,0,-0.1),App.Vector(0,0,1),180)) Screenshot from 2017-11-03 13-56-51.png now its time for pose ;) Here is an example of the "joint" structure i try to visualize and will later g...

FeaturePython shape, union sphere and cylinder

I want to create a visual shape in a FeaturePython that consists of a union of a cylinder and a sphere, what is the best way to achieve this? The shape is going to visualize a joints orientation and limits in my "RobotCreator" workbench. Currently i only have a sphere that is implemented l...

Re: URDF Workbench, robotics

Here is an small update, progress is slow as usual, but now i have something that can export to SDF with 3d shapes and joints . Joints are created by selecting two objects and then running the "createHingeJoint" script that will create a joint object that keeps track of parent/child, posit...
