Building a face from a circle

[Stu Abinavski]

Hello
I need to build a face from a circle. My few attempts have ended in exceptions.
What is the right way to build this?
Thanks in advance.

There are many ways for doing this.

The minimum code way is using IStdShape_DG.Disk(). It will create a disk in the xy palne, which can be moved around.

I have hacked PatchForm_Load() of the installed C# Patch sample to check:

Code: Select all

//Before m_iEntity = iStdShape.Cylinder(m_baseRadius, m_topRadius, m_height);
m_iEntity = iStdShape.Disk(0, m_baseRadius);
// Set locationg and orientation
IFrame_DG iFrame = m_iEntity.GetLocation();
iFrame.SetOrigin(0, 0.5* m_baseRadius, 0);
iFrame.Rotate(0.25 * Math.PI, 1); // Rotate around Y axis

It works.

Another way is via IBRepBuilder_DG. Search samples for IBRepBuilder_DG to find a way to get it.
