Reverse Engineering Ext - WF2 |
|
|
Hi,
Does anyone know a way, preferrably through wf2, to change point cloud data
numbers to reference a different csys? Easily done with datum points.
I have point cloud whos origin I'd like to move.
Thanks

I suppose you could create an offset csys, use it to generate a transformation |
matrix and then use those values to change the x, y, z values of each point.
Sounds like a programming job and AFAIK Pro/e doesn't mess with reprocessing ibl
data, chiefly, especially in REX, because it's not concerned with that data or
those points but with the surface you create from the data.

You could EFFECTIVELY move the csys in a couple ways |
* Produce the surface at the default csys then Copy>Transform the surface to the
new csys location
* Create an offset csys before importing the points to produce the surface, then
pick your new offset csys instead of the default when you create the surface.
After you have the new surface moved to the desired location, maybe you could
generate a new ibl file. I don't know all the internal capabilities of REX.
Something to look into if you're really serious about getting the ibl data with a
transformed csys.

Assuming your point cloud is 'dumb geometry' why not create your new
co-ordinate system, then export the points relative to that. When you
re-import it, it will be relative to your new zero point with no legacy
data in the file.

As far as I can tell, there is no mechanism to save the point cloud relative
to a new csys. I can save it and can enter a filename only.

'save a copy' is not available at that point. Under the 'Points' pulldown is
'save' which has no csys option.

If "at that point" means you are not in Standard Application mode, you might
want to try it from there. That's how you'd do a "regular" import feature datum
point array. |

If the part isn't super-secret, mail me a copy & I'll have a look.

These are not your typical points. They don't carry parametric info. There
are over a million of them. The 'insert data from file' along with having
the RE Extensions automatically put Pro into the rex mode.
I don't think one could handle a million points thru standard point
features.

Not talking about point features. If you read the data in and end up with an
import feature point array you should be able to export the data referencing any
coordinate system you chose. If it were me, I'd create a small data set and
figure it out.

"read the data in and end up with an

If I insert from file an iges point file I get an import feature. How do I
export that? Any other type of point file (pts, ibl, vtx) imports to point &
faceting tools. During point manipulation I can save the point data but only
to pts or vtx files with no csys option.
I've created an import feature consisting of points fr

That should be as simple as creating the desired csys, Save a Copy, select Datum
Curves and Points, select the desired csys (from Standard Application mode).
I'm not sure how much good this'll do you. I just tried to read a million point
IGES and couldn't. I'm using a pretty old machine with only 3/4 GB RAM. The
million point IGES is huge; about 237 MB.

"During point manipulation": I don't have REX and am probably not understanding
what you are dealing with after import.
For what it might be worth: Using WF2 Foundation I can create an Independant
Geometry feature and read a million point *.ibl or *.pts (about 12 MB) into it.
It asks me to specify a csys to use for import reference. This creates a set of
curves from the data rather than a point array, though, and beyond that I'm
lost. Sorry, probably not much help... |
