Can a specific map scale be set?

[PeterLen]

Say I have a basemap that has 15 zoom levels where zoom level 18 has a map scale of 1:2287 and zoom level 17 has a map scale of 1:4514.  Is it somehow possible to set the map extent to what it would look like at a scale of 1:3000?  I have a situation where 1:2287 zooms me in too close and 1:4514 is a bit too far out.  I would like to see the view at a scale of 1:3000, which would be just about right.  I have a feeling that the scale can only be set to the nearest zoom level that  the current map is set for and if I want to get to a scale of 1:3000, I just need to find a map that has been set to use a zoom level at that scale.  I am not in a position to actually reset the levels, such as what is listed in the Set visible scales | ArcGIS API for JavaScript 3.32 , however.  Just wondering if it were possible.

Thanks for any thoughts - Peter

for development purposes I like to declare the var view; outside of the require statements so I can get and set the view's properties in the browsers developer tools.

Maybe this can help you out. For your particular case I'd do: view.scale = 3000 in the dev tools of the browser and see if it fits my needs.

You need to set the Constraints.snapToZoom property. to false

In MapView, snapToZoom is true by default.
