ArcGIS Pro 2.8 API Reference Guide
MMin Property (EnvelopeBuilderEx)
Example 

ArcGIS.Core.Geometry Namespace > EnvelopeBuilderEx Class : MMin Property
Gets or sets the M minimum of this instance.
Syntax
public double MMin {get; set;}
Public Property MMin As Double
Remarks
If the value passed in to set MMin is greater than MMax, then MMax will also be set to this value. To set both the minimum and maximum values simultaneously, use SetMCoords.
Example
Coordinate2D minCoord = new Coordinate2D(1, 3);
Coordinate2D maxCoord = new Coordinate2D(2, 4);

Coordinate2D c1 = new Coordinate2D(0, 5);
Coordinate2D c2 = new Coordinate2D(1, 3);
