A little delay when first using ISnappingEnvironment.

Question asked by mik1971 on Nov 4, 2015



I use ISnappingEnvironment in my custom tool for ArcMap 10.3.

The first time I draw a new point (click on a map)  - I see a delay (about 3 seconds) and graphics (point and label(text)) disappear.

Next points appears with milliseconds on the screen.


If I close/open my tool I DO NOT see that delay - meaning it is once for an ArcMap session. If I close/open ArcMap I can see that delay.


I draw a point on MouseUp(), but initialise a snapping environment earlier.

The first point is not snapped to anything.


So why it is delayed only for the first time?

Thanks for any help.
