Projection points onto surface

[MWSS]

Hello
I'm new with CATIA and I need help.
I need project points into a surface and need export the coordinate to a file, csv, txt, or other format.

I found one macro in this forum to create parallel planes and project a line onto surface, but I can't extract the points.

I need this urgently.

Anybody can help' me?

Best regards
Marco Wilson

How many points do you have? For several points you can fill coordinates manually. Goggle for export points from Catia V5. There is some nice free app. Don't remember the name.

The attached excel has script built in to read from catia. I did not write it, but have used it several times.

Hello rickyt
I try use the script but now I have a new problem.
I create parallel planes in x, y directions and intersect with my surface. How do I can create points in the intersections lines?
I run the scrip and I recognize only 3 points.
In the next image show a little bit of my catpart with the projection lines.

Best regards

You need to have points at all your intersections.
Intersect your vertical lines with your horizontal lines or planes.

I use this command Shape -> Generative Shape Design -> Intersection and the result appear in the next image.
I run the script but he recognize only Point.19, Point.20, Point.21.
In Multi Output.38(Intersect) we see the intersections lines.
It is necessary convert or what else this intersections in points? If I move the mouse and add manually one point the script recognise that point, but not the others.

 

[rickyt]

Excel Macro looks for points versus intersects, even though your intersect results are points.

you can do a few things.
Turn your history off (create datum icon) and re-intersect your curves.

OR create a new geometric set, grab your multi outputs, rmb copy, paste special as result to your new geometric set.

OR same as above but paste special as result to a new empty file.

OR grab all your intersects , rmb > selected objects > isolate.


The excel macro grabs all the points from the geometric set selected, after you initiate the macro.

Hello Rickyt
I follow your suggestion but I don't have success.
I found one tool bar (Time saving Toolbar) and I use this option "Convert Isolated Points to Coordinates".

With this option I convert the points and lately i export to Excel.

Where I can find one macro only to convert the points to coordinates?

 

[rickyt]

This is the only one that I have used.
Once points are in excel, you can then format cells to a number and choose how many decimal places.
Then save it as a csv file.

answer: nowhere

why?

Because what you want is specific to your needs

So what's next?

Either enjoy the free 2 step solution
or
Pay someone to do what you need
or
Learn scripting and do it yourself

if you believe in Santa / Unicorn, you can wait here and see if someone would do it for free... but it might take some time.

up to you.

If you want to learn I suggest you open another Thread and post your code, the error message, the result and what you expect. I will help.

Good morning everyone
Thank you in advance for your support.

Itsmyjob - Sorry if you hurt your feelings.
I'll leave those comments to you

I need help and I try here in this forum.
I work with Solidworks and for that software I've created the code to do what I want. I have the need to apply this to Catia.

Best Regards

Hello Rickyt
I follow your suggestion but I don't have success.

could you present a screen grab of the result after you isolate the points following Rickyt's solution?

no hurt feelings... like I said I will help you to get there, but be ready to show your progress.

Afternoon itsmyjob afternoon
I have successfully successfully exported the points. However I need help again.
I would like to automate the mu process.
I created a macro to create me parallel plans with the following names:
"Plans XZ" and Plans YZ.
Is it possible to use the "Intersection" command directly in my code?
I have already recorded a macro to do this but it only works on this model.

My other question is that I need to create normal lines to the surface from the previously created points and check the angle value in the 3 directions.
Below I send an image of what I intend.
If you can help me, I thank you.
