How do you go about hardclipping a TIN in Arc10? Previously there was a modify TIN tool, but I cannot seem to find it. So my question remains, how do I go about clipping a TIN with a polygon layer?

Edit TIN. Arc Toolbox -> 3D Analyst Tools -> TIN Management -> Edit TIN Add in the polygon Feature class and choose for height field and hardclip for SF_Type

Works for me... thanks Jakub – Andrew Nov 29 '10 at 17:48
I had been performing the above operation to clip my TIN and wasn't appearing to get any results. I found the forum post by @Jakub as linked in the answer by @SaultDon and once I restarted ArcMap the TIN drew correctly (I didn't have to rerun the tool). Thanks for the post. – Jason Jul 6 '11 at 18:25
Just to clarify, "and choose for height field", should be "and choose none for height field". – Mort Jul 10 '15 at 10:23

Try the Edit Tin tool and if that doesn't work,

try to use the clip tool to get your hardclip after your TIN has been converted to a polygon.

Here is a forum topic from the ESRI forums on an issue with this tool, so inspect your results.

No, because the clip tool only works with features, not surfaces. The TIN is not an option to apply the clip to in the drop-down menu. – Andrew Nov 29 '10 at 17:20
Andrew, looks like I was editing while you responded, too fast for me, see if my revision now answers what you were looking for. – SaultDon Nov 29 '10 at 17:31
Thanks I just couldn't find where it was :) – Andrew Nov 29 '10 at 17:48
