This command has the following parameters:
MeshMode - Defines the meshing mode. If MeshMode = SketchMesh, each object is meshed individually and then merged. If MeshType = EnvelopeMesh, meshing is performed based on the envelope surface;
MeshControl - Defines the mesh control mode. If MeshControl = BySize, mesh is controlled by size, where MinSize = minimum mesh face size, MaxSize = maximum mesh face size. If MeshControl = ByCount, meshing is controlled by segment count, where MinCount = minimum number of mesh segments, CurveMaxCount = maximum number of mesh segments.
BreakingAngle = Angle to break curves into polylines;
SmoothControl = Defines whether to smooth points. If SmoothControl = ExactMesh, every point appears in the output mesh. If SmoothControl = SmoothedMesh, nearby points are merged before meshing, where NoiseNeighbors = number of neighboring points to merge.

Select the geometric objects to be meshed and run the command.

Here is an example you can try: DMesh.3dm.
