Cut the geometry in half in results

I have a 3D model which I want to cut in half for beter visualization. Is it possible in SimCFD? I have attached a snap illustrating this point.

guess we can do it using Z-clip, but it keeps cutting the model as I rotate, depending upon the orientation. Is it possible at all in SimCFD?

 

Thanks

If you right click on a plane you can select "Clip" to clip the geometry, then as you view the model as shaded it will appear as a section view.

Thanks Apollo. But there is some anomaly here.  When I  try to cut the geometry exactly in the middle plane, it cuts at an offset of that plane. Have look at the attached pic.

From what I understand, the clip feature "hollows out" the geometry and thus only the outter most surfaces of walls and BCs remain. Then it cuts these surfaces off at the clipping plane and thus you get a sealed surface of walls, BCs and clipping plane, giving an illusion of cut geometry. But as you can see, the walls and BCs are not cut exactly at the clipping plane and extend beyond it. This doesn't look like what I want. The workaround I am using is to adjust the position of clipping plane so that the "actual cut" is at the middle plane, but this still leaves very small projections of these walls uncut and clabbers the view. 

 

Am I missing something here, if I assumed it should cut exactly at the clipping plane?

 

Thanks

OJ,

 

The clipping plane does tend to have a small amount of error where the associated surfaces extend beyond the clipping plane location.  I would suggest that you add that to the idea station to improve the clipping plane precision.

 

You are doing what Apolo suggested correctly.  The z-clipping method would be another option, but is a bit slower and will not be as smooth looking.

 

Thanks!

Sure, have raised the request in idea station.
