Importing points to make a curve for revolve

Importing points to make a curve for revolve

Importing points to make a curve for revolve

(OP)
I have a matlab code that generates points in a .pts document. The points (10000 of them) make a curve and I want to revolve that on Pro E to make a bottle-like shape.

What I did was:

Insert>Model Datum>Points>Offset Coordinate System

and uploaded the .pts file with csys as reference.

This uploaded all the points.

Then I did:

Insert>Model Datum>Curve>Thru Points

with Spine and Whole Array selected.

This creates a curve through all the points I uploaded but afterward when I try to revolve it does not work.

The error I get is:
The selected geometry can not be used by this tool. Please select new references.

After I make the curve by tracing the points, what should I do in order to make a revolve?

Is there a different way?

Thanks in advance.

RE: Importing points to make a curve for revolve

Whatyou want to do ?
Solid or surface ?

Wildfire is very nice, if you know,
how work with him

RE: Importing points to make a curve for revolve

(OP)
I would like to make a surface by revolving it? Is my approach the right approach? If so what steps should I take next?

RE: Importing points to make a curve for revolve

(OP)
By the way, my points are in this form:

0  0  0
1  2  0
2  5  0

etc etc

and it makes a curve similar to a cubic equation


To clarify, I would like to import those points and revolve it to make a bottleneck kind of shape.

Thanks in advance

RE: Importing points to make a curve for revolve

Why 10,000 points? What's the distance between them? Maybe too many points in relation to the tolerance. Have you tried curve from file using an .ibl file?

RE: Importing points to make a curve for revolve

(OP)
the distance between the points are very minimal

Example:
x y z
8.8899995e+000  2.0261072e+001  0.0000000e+000
8.8899994e+000  2.0259040e+001  0.0000000e+000
8.8899993e+000  2.0257008e+001  0.0000000e+000
8.8899993e+000  2.0254976e+001  0.0000000e+000
8.8899992e+000  2.0252944e+001  0.0000000e+000

I am unsure how to use .ibl files.
Can you clarify and perhaps explain the steps to take?

RE: Importing points to make a curve for revolve

(OP)
after doing some research i found out how to use .ibl...
i put it in this form:
     Open Curve
     Begin section ! 1
     Begin curve ! 0
then points
     Begin section ! 2
     Begin curve ! 1
more points.

However I still have the same problem I was facing with my 10000points method. I have the curve down but I can't revolve it. I don't want to use spline manually and try to trace the line. I would like pro e to trace the curve in sketch mode so that I can revolve it.

The picture I post shows a blue curve line. Lines drawn in sketch mode are yellow.  

RE: Importing points to make a curve for revolve

Try deleting four or five contiguous point groups between each point that you keep.
From the sample, the x points are .0000001 apart, and I hope that's in English, not Metric. It seems like a ridiculous amount of points.
 Use ibl to create the curve, then create a rotate feature and copy the spline created. You are revolving it about a centerline, correct?
Can you upload the file?

RE: Importing points to make a curve for revolve

Use revolve, make sure you choose surface, not solid. Create an axis of revolution first and import the points. It works for me.

RE: Importing points to make a curve for revolve

(OP)
I am beginning to think I am doing this incorrectly.

What I am doing is first draw a line in sketch mode on front plane.
Then upload ibl by
Insert>Model Datum>Curve>File>Select csys

Then I select the curve and do revolve. It tells me to select a sketch but I can't select the curve.

Are these the steps you took?
 

RE: Importing points to make a curve for revolve

Try creating the revolve with its own sketch. Then use the curve (in wf3- Sketch; Edge; Use) to create the sketch.
