So I have come here to ask what is the recommended way to programmatically add or change the z values of the two end vertices of a polyline, based on a two values from the feature's attributes table.&nbsp;&nbsp;</P><P>example:&nbsp;</P><P>1. change the z value&nbsp; of vertex 1 according to the value found in the height1 attribute</P><P>2. change the z value&nbsp; of vertex 2 according to the value found in the height2 attribute</P><P>I am having trouble finding the appropriate approach. Do i use applyEdits()&nbsp; and change the polyline in place or build a completely new polyline and add to the featurelayer?</P> Thu, 16 Sep 2021 10:49:46 GMT yunsung 2021-09-16T10:49:46Z https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/programmatically-adding-z-value-to-a-polyline-from/m-p/1098857#M74683 <P>Hello All,</P><P>I have googled and tested different approaches for a long while.
