Hi
I want to display 2D of 3D object (orthogonal drawing). Just wanted to know what is the best way of doing this.
Thank you
Ibi

Hi Ibi
There are different ways to do it. They depend significantly on the objective and type of the object(s). Could you tell a bit more about the purpose? Printing, getting a silhouette for calculations, etc.? Is it a mesh section or other type or whole mode, etc.?

I have a number of mesh objects, I want to draw Oxy, Oxz or Oyz views. I want to draw orthogonal views of mesh objects.

Ibi,

If you just need to set the view point it is easy:

You need to get IFrame of the eye frame (~=Camera) like:
m_kernelCAD.GetView() > IView > IFrame
The last one is a cast (query)

And for the obtained iFrameEye do:
iFrameEye. ResetOrientation() (Or Reset() to set position = global axes also)

iFrameEye determines position of eye frame wrt the global axes.

This will make the view to show the x,y axes as if 2D view.

Call iFrameEye.RotateStd( -90, 0 ); after that to show x,z axes.
Call iFrameEye.RotateStd( 90, 1 ); to show y,z axes

It is demonstrated in the View Point sample (C++). Sorry we do not have VB Net version of it. And C# version does not have the x,y etc. buttons.

In C++ it is done in CViewPointDlg::OnProjectionXY() etc. handlers.

You can also disable view rotations with the mouse to make it 2D view:
IView > IView2 > IView2.Enable(EEnableBit.eEnableRotate, False)

Like in CrossViewForm.Init() , Samples\NET\C#\View\CrossView\CrossViewForm.cs

Kind regards
