Macro Output
The data output from Import-STL is presented in the form of a macro file that can be read into MODEL in order to create the corresponding primitives and associated hierarchy.
Data Structure
When an STL file is translated into a MAC file and this is read into AVEVA E3D™, all geometric parts are converted to primitives which form a single EQUIPMENT or VOLUME (VOLM) per STL file. Import-STL uses the name from the STL file as the EQUIPMENT (or VOLM) name.
Geometry Hierarchy
If a BOX, PYRAMID, CYLINDER or EXTRUSION is recognised by Import-STL, then these primitives are added to the EQUIPMENT or VOLM element. Negative primitives are added below these primitives.
Any Solid Polyhedron (POLYHE) elements are also created directly under the EQUIPMENT or VOLM element.
Any other closed volumes that are not recognised as being any of the above AVEVA E3D™ primitive types are added to the EQUIPMENT (or VOLM) element as a SUBEQUIPMENT (or SVOLM). Each face with one or more holes in it is represented as an EXTRUSION with each hole represented by a NEXTRUSION. All remaining faces, with no holes, are represented by AVEVA E3D™ POHEs, each face of a POHE being represented by a single POGO (polygon) element. The POHEs are added under the SUBEQUIPMENT.
All non-closed volumes are split into non-manifold surfaces. Each non-manifold surface is then treated as a closed volume as detailed previously.
