LRA to XYZ Conversion
LRA to XYZ Conversion
(OP)
Hello everyone,
I am about to reverse engineer one complex tubular structure and everything I have is CNC bender coordinates in LRA (Lenght, Rotation, Angle) format and Center Line Radius. I need to convert it to XYZ to draw a centerline in Solidworks, because I need to have a 3D model.
Is there any free LRA to XYZ Converter, I have found only commercial one which is not cheap (in terms of our company) and this is needed only once.
Or maybe someone has an access to such software and could help me converting those coordinates?
Any help will be appreciated.

This question properly belongs in forum559: DASSAULT: SOLIDWORKS 3D Design.
If you have data in LRA format, you should be able to create a 3D sketch directly from it. If your tubular structure is welded, you are most of the way to being able to use SolidWorks' welding feature.

RE: LRA to XYZ Conversion
I think it would be about as easy to build the features using LRA references as to recreate the software, but either way, the tough part is bend allowance calculation - which is simple geometry and is in many discussions - recently in http://hackaday.com/2016/05/18/the-art-and-science...
Other than that, the conversions can be done with whatever local coordinate systems/datum planes are available to build the model.
The other method is just using augmented matrix multiplications to transform the coordinates while walking back along the list of bends, just like the bender works.
I wish I still had it, but it's with another company, and probably they discarded it.
