 | | Sorting parts by location —Larry Pieniazek
|
| | | Does anyone know if there exists a utility to sort parts in a model file by their "cut plane" location? I know I can sort by X Y or Z values but what I am actually interested in is sorting using a cut plane that is perpendicular to the eye vector in (...)

You could hack up a Perl script which computes the euclidian distance between the viewing point and the origin of each individual part, and concatenates this number to the beginning of each part line.

| | | | | (...) Well I am sort of doing that right now, although not in perl. I chose to use my company's product, sort of as a learning exercise. If someone has perl code that recognises the various line types that would be spiffy. If you have the formula (...) (23 years ago, 28-Aug-01, to lugnet.cad)

If the viewpoint is at location (a,b,c) and the part is at (x,y,z), then the distance between them is: ((a-x)^2 + (b-y)^2 + (c-z)^2)^0.5 Since all you want to do is sort, there's no need to take the square root after summing the squares.

| | | | | | (...) Bram Lambrecht gave you the formula. Depending on what you want to do and what kind of viewing transformation (if any) you are using, the euclidian distance _may_ be the wrong kind of measure to use. But it is probably an ok approximation... (...) (23 years ago, 28-Aug-01, to lugnet.cad)
