There was not enough memory to create a new model.

This DTM external is incompatible with this version of MiniCad or Blueprint.

One or both of the DTMs for the cut & fill DTM are marked as "always recalculate"; you must recalculate them with this checkbox turned off.

To create a new DTM you must be in a layer which does not have a DTM associated with it; either switch to such a layer, or create a new layer. To recalculate or edit the existing DTM, choose a different menu item.

The model could not be recalculated because there are no longer enough 3D loci and/or 3D polygons in the data layer.

An error occurred while threading contour lines through the model.

The DTM information could not be read from the drawing because of a bad (old) version number.

An error occurred while reading DTM information from the drawing.

There were no 3D loci or 3D polygons selected, so none were changed.

You must select at least one 3D locus and/or one 3D polygon in order to change their elevations.

An error occured while creating the DTM.

There must be at least two existing DTMs in order to calculate the cut and fill between DTMs.

This drawing contains no DTM, so your command was not executed.

To create a DTM, activate a layer which has at least three 3D loci, or at least one 3D polygon with at least three vertices.

You have canceled the creation or changing of a DTM; no change has been made to the drawing.

An error has occured.

Ran out of memory after some graphic objects were added to the drawing.  Your last change to the DTM information has not been updated.

Could not write DTM info to drawing.
