Export compound shape

Hello, I am trying to export a pure compound shape in .stl format. It's a kind of cuboid made of smaller cuboids. I can export the shape, but when I try to import it to SolidWorks or Matlab I get errors saying that there are too many facets or that more than two facets share an edge. Is there a way ...

Different results from force sensor and graph

Hi Coppelia I noticed something strange happening, and I don't understand why. I am trying to read the results from a force sensor. I do it in two ways: programmatically and using a graph. The thing is, I get different results! In the script, I call the sim.readForceSensor a couple of times (10-ish)...

Re: Grasp issue

Hello, The object I'm trying to grasp is a pure compound shape. It's a group of small cuboids that make up something like a 3D puzzle piece. The problem is that because of the shape of the object, the gripper finger is partly on the surface and partly in the air, and so it falls through the surface ...

Grasp issue

Hello, I have a problem with the RG2 gripper. The gripper needs to grasp an object & it's programmed as recommended: the object is attached to the gripper attach point, and the gripper force and velocity are set for the grasping to appear realistic. However, the 'fingers' of the gripper do not a...

Re: Pos./orient. of inertia frame & COM relative to shape frame:

Hi, Yes, the inertia matrix can be set in an absolute manner via Set inertia matrix and COM relative to absolute frame . But, how do I set the inertia frame ? The only thing I can find is to set it in relation to the shape frame, via Pos./orient. of inertia frame & COM relative to shape frame as...

Pos./orient. of inertia frame & COM relative to shape frame:

Hello, My question has to do with inertia frames of shapes. I imported a shape from SolidWorks, with calculated COM and moments of inertia. In Coppelia, I'm assuming the inertia frame is the same as the shape frame. However, my inertia frame is different in Solid. So I would like to use the 'Pos./or...
