Clip Volumes Along a BSpline Curve

Michael Bardin
Offline

I've been trying to produce a series of sections within a GC model. Ive been trying to create clip volumes at specific spacings along a curve. Ideally I would like to be able to replicate the clip volumes along the curve so they update automatically if the curve changes.

Is this something anyone else has managed to do?

Thanks

    Hi Mike,

    Sure can. 

    Just need to place a coordinate system (say byspacingalongcurve) on the BSpline. 

    • Pace a ClipVolume node, you will need to set the left.right,front,back,top,bottom for the volume.
    • Then place a ClipVolumeStyle node that will control the forward,back,cut settings(although I am having an issue with the forward not turning on in the saved views, so watch out for that )
    • Then you can just place a Section node and link up the ClipVolume (In the Section node you can set the base name for the saved views).

    I did find I needed to add another coordinate system to rotate the section to the orientation (along the line) but it depends which direction you would like to view.

    Not a great description so I have attached a sample DGN.

    Thanks

    Thanks Wayne, I was nearly there I think. I wonder if the issues I was having may be from use of 3D BSplineCurve, Ill recreate on single plane and go from there.

    Many Thanks
