Intersect Error: Invalid Topology and The table was not found

[YichiLiu1]

Hi all,

I am having problems with Intersect.

I would like to intersect two polygon feature classes. One of them is a buffer created from line feature class (e.g. stream) and the other one is vegertation cover. However, it always throws me this error.

I've tried repair geometry and it did fix the problem. And if the buffer polygon was created from polygon feature (e.g. pond), the Intersect worked fine.

How can I solve this problem?

Thank you very much!

OK, I found the solution myself. Just in case anyone wanted to know as well, this is what I did. I exported the feature classes, but disabled M values and Z values. Then I did Repair Geometry and both intersect and clip worked fine after that.

I also had the same problem intersecting a polyline feature with a route feature, but investigated a similar solution to yours. However, my "export" of the route feature used this article: How To: Remove Z- and/or M-values from a feature class (esri.com) . Additionally, I did not need to use the Repair Geometry tool.
