I'm trying to figure out how to enable this via ArcObjects. I can cast an IMap or IGroupLayer to ILevelMasking to retrieve the levels as a string, but nothing in that interface allows me to enable the option. Any ideas?</SPAN></P></BODY></HTML> Fri, 28 Jul 2017 18:35:23 GMT https://community.esri.com/t5/developers-questions/arcobjects-how-to-enable-associating-levels-to/m-p/507300#M3461 mikebaran 2017-07-28T18:35:23Z Re: ArcObjects: How to enable associating levels to masked layers? https://community.esri.com/t5/developers-questions/arcobjects-how-to-enable-associating-levels-to/m-p/507301#M3462 <HTML><HEAD></HEAD><BODY><P><SPAN style="color: #242729; background-color: #ffffff;">Figured it out.
