[Magnus Forsberg]

is there a way to import a dat file as the geometry

Yes.
Make a dat-file, using all the formed surface you want to print.
Make sure all vertices are unified. No rounding errors.

Use File/Import from DAT. Choose an appropriate direction to suit the image you have of the pattern.

Choose Import a DAT File / Overwrite and import projection data

Select your file of surfaces.

Draw your pattern.
