Re: Search for a comparison of PDM,PLM, DMS

Aras PLM have a decent description of what it does.. https://www.aras.com/en/support/aras-innovator-101 depending on what platform you use they might do the same thing but describe themself in different ways. In the end all those fall under "marketing BS buzz word" to describe a platform t...

Re: Fully defined sketch, multiple solutions

if you take both points as defining a vector in plane ( or space for 3D ) Sure, That can work for detection, Using this for a solution is what i am talking about when i say "assumed constraints". the equal line constraint do not care about relation between points only distance. We have to...

Re: Freecad for shop use? Anyone use this 4 manufacturing?

I have mainly used it for 3D prints used in production, test fixtures, jigs, fittings, holders etc. other then that i have made a metal RF shield for a PCB. Have also done a bunch of things for fun in my basement with my CO2 Laser cutter, CNC mill and my 3d printers. What i have found valuable is th...

Re: Fully defined sketch, multiple solutions

of cause its possible to improve with enough dedication and effort. :D What i thought of was stupid. A simple example of where i went wrong. given: p1 = {x=2,y=10} p2 = {x=-5,y=15} Just checking the signs of the points can not tell us if it have flipped. I thought that if p2.x becomes +5, then the s...

Re: Fully defined sketch, multiple solutions

Have the dev env set up now, have read through most of the fc-solver document and looked at the sketcher code and planeGCS, will play around a bit with the interface between sketcher and planeGCS and see if i can inject a few extra constraints to planeGCS for sketcher equal constraints to prevent fl...

Re: Fully defined sketch, multiple solutions

Nice, thanks. I doubt this will be a challenge after reading up on the topo-naming issue and possible solutions when realthunder started his work.. that was some heavy reading... Maybe i will find the time to contribute some code. (main issue is that my overtime compensation is too good at my daytim...

Re: Fully defined sketch, multiple solutions

As a side note, the culprit for flipping is the equals constraints, because they do not care about direction. Replacing them with length/height constraints, which do care about direction, solves the flipping: Would it not be a good idea to store the current sign (+ or -) in the equal constraint so ...

Fully defined sketch, multiple solutions

A poorly designed sketch can be fully defined while also have multiple solutions. Is this something we can detect and warn the user about? The following behavior is not what the user expects, but i do not know if it should be classified as a bug. Stair origo offset = 1000 1.png origo offset changed ...

Re: URDF Workbench, robotics

Hello, thank you for bringing this project to life again.

Will try to catch up wirh both recent ROS, Gazebo/Ignition and FreeCAD development :)

But I am a bit busy at work building a physics simulation framework ^_^
