the above mentioned faro arm compares the product to the iges file and verifies . these are nice the one i used was 17000 out of the box . they are absolutely necessary for 5 axis swarfed surfaces on airframe parts . as to point cloud to parametric solid i have no idea how to do that so i will take your word for it . what i was infering to was this part of the statement
Even if it did, one would have to scan a "known-good-master" at each step of the production for the test scan to reference against you wouldnt need a known good master if you were able to use an ices or other model to compare it to . that was the point of my comment but i now see the point cloud issue at hand . and your solution However, in this case I guess that you could create a virtual point-cloud from the IGES file for point-by-point comparison. which is basically working the problem backwards is exactly what the faro arm does , and is what i intended to convey by my previous post . now how it does it and why ??? well i never asked as the parts we were checking were 12 k eack so i was more worried about proper operation :) On Wed, Jun 12, 2013 at 10:50 AM, andy pugh <bodge...@gmail.com> wrote: > On 12 June 2013 13:52, jeremy youngs <jcyoung...@gmail.com> wrote: > > > not exactly just compare it to an iges file that will never change . or > > other parametric solid > > Going from a point-cloud to a parametric solid is not even slightly easy. > However, in this case I guess that you could create a virtual > point-cloud from the IGES file for point-by-point comparison. > > -- > atp > If you can't fix it, you don't own it. > http://www.ifixit.com/Manifesto > > > ------------------------------------------------------------------------------ > This SF.net email is sponsored by Windows: > > Build for Windows Store. > > http://p.sf.net/sfu/windows-dev2dev > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users > -- We conclude that the Second Amendment protects an individual right to keep and bear arms.
