19 January, 2017 - V65

• Bug fix for Excel interface and "File > Output > Selected Grid/Surface Components" for fully populated option.
• Support for AUTOCAD DXF EXTENDED ENTITY DATA (EED).
• EED allows you to tag each DXF ENTITY with custom data attributes.
• Below are a list of the EEDs supported by Map3D.
• Most CAD systems will allow you to add these EEDs to your DXF.
• For example Deswik calls these "attributes", hence from within Deswik you can now create Map3D geometries including specification of Map3D block names, colours and mining sequence
• Export each block using DXF-POLYLINE/POLYFACEMESH
• Deswik attributes are exported to DXF as AutoCAD Extended Entity Data.
• The attribute names (attributes names are not case sensitive) are defined as follows:
• MAP3D_BLOCKNAME - name of the block (default is blank).
• MAP3D_BLOCKCOLOR or MAP3D_BLOCKCOLOUR - Map3D colour number (default is the Deswik defined colour number).
• MAP3D_BLOCKTYPE - 1 for FF, 2 for DD, 98 for inactive FF, 99 for inactive DD, 0 for grid plane (default is 1 for FF).
• MAP3D_MSTEP# - # is the mining step number (default is mined at step 1).
• MAP3D_BLOCKNUMBER - unique block identifier number (default is a different unique number for each DXF-POLYLINE/POLYFACEMESH or each DXF-3DFACE).
• Attributes names are not case sensitive.
• All attributes can be defined as strings (group code 1000), integers (group code 1070 or 1071) or real numbers (group code 1040).
• All attributes are optional - defaults are supplied as specified above.
• Note that if no Map3D defined attributes are specified, the DXF will read in successfully provided you are using DXF-POLYLINE/POLYFACEMESH.
• Map3D will simply assume that each DXF-POLYLINE/POLYFACEMESH is a separate block.
• If you are using multiple DXF-3DFACEs, Map3D may have difficulty grouping these into blocks.
• Problems with this occur only where adjacent blocks share their corners and have the same name.
• MAP3D_BLOCKNUMBER can be used to identify the DXF-3DFACEs that belong to separate blocks.

4 January, 2017 - V65

• Enhanced Excel interface.
• Modified DXF Import for multiple files.
• Previously Map3D had difficulty distinguishing between adjacent blocks that shared the same corners.
• If blocks are in separate files, they are now kept separate.
• If blocks have different colour numbers or different names, they are now kept separate.
• Stress, Strain... menu display fixed.
