Site Model has 'edges'

Recommended Posts

I keep getting 'edges' on my site models.


Yellow Highlighter:



I'm trying to use the split tool to clean up the edge of the topo lines before I convert, but this still seems to happen often.


Thoughts on what I'm doing wrong?

Ways to fix this?

Should I just crop the edge out?


Here are the original topo 3D polylines:

Good question. I've had this too + wondered why it was happening. I just cropped the offending edge/s out like you say but be good to know why it happens + if anything can be done to prevent it

Yes, I also just crop a bit inside.


Generally you can fixit manually of course by following the edge flow

and adding a few missing or deleting a few redundant points and such.

Sometimes I have that ambition - but this is basically just pointless 🙂

Just crop it a bit off and you are fine.

Agree with all of the above. For most single family residential sites I ask the surveyor to include extra area in the topographic data so that I can crop out the weird random anomalies at the edge(s).
