ZMin defines the lower elevation boundary of the envelope.

The following C# code shows how to read and write the ZMin value:
IEnvelope env = new EnvelopeClass() as IEnvelope;
env.ZMin = 2;
double zMin;
zMin = env.ZMin;
The following VB code shows how to read and write the ZMin value:
dim dZmin as double dim pEnv as IEnvelope set pEnv = new Envelope pEnv.ZMin = 100.0 dZmin = pEnv.Zmin
