Summary

0000623: InCorrect Data in PCurve

Description

This bug has been added by Narasimha to
http://www.opencascade.org/forumorg/bug.php?bug_id=71&f=8 [^] .

I was trying with the sample "linkrods.step" provided with Standard OpenCascade
installer

To see the problem follow these steps.

1. Load linkrods.step.
2. Convert the model to B-Spline using "BRepBuilderAPI_NurbsConvert"
3. Look at the Face No. 9 in the following loop

TopExp_Explorer Exf;
for(Exf.Init(nurbShape, TopAbs_FACE); Exf.More(); Exf.Next())

Two curves on this face has Data Explosion (For me I saw it on the first
PCurve).

In otherwords the UV values of the PCurve are going beyone the bounds of Surface
UV values and they are not correct.

This particular Linkrods.step has this behavior on more than one face.
