Title: some improvements for the vehicle turning simulation module
Post by: cr_raul on August 05, 2010, 03:50:17 PM
hi Lars,
I was thinking that it would be a great thing to have an option for drawing only the boundary of the swept path and maybe an automatic hatch for it. It would make things a lot easier. and maybe you could make the window fixed size like the other menus in cadtools.
I tested the VTS on some plans and got good results, well, excepting  some U turns but this was because the trailers used for carrying the blades of the  wind turbine generators have additional steering capabilities... so with a standard trailer of the same length it seemed to be out of track.

Hi!
Only outer boundary is something that would be great but I've no idea how to do this without slowing down the process dramatically. Every sweepline needs to be evaluated against the vehicle path at small intervals and that takes forever. A concave hull would do the trick but the only sample I've seen is also to slow. Other turning software has that feature so it must be possible to achieve.

The accuracy is quite good, I've compared it with Autoturn. Additional steering is probably hard to manage, I'm satisfied with it as it is now (free). I don't know how much money they charge for one of the professional turning software.

The turning command has been released as a standalone software for Brickscad and I'm also trying to port it to Microstation, perhaps there are some built-in functions in the API that helps me add outer boundary.
