PASS/EQUIP → Working with PASS/EQUIP → Geometric kernel, solid model generation
Starting from version 2.08, the program uses geometric kernel C3D developed by C3D Labs Company. This kernel provides an automatic creation of high-detailed solid model of vessel (creation of reinforcing pads, fillets, cutting holes in the shells, etc.), and its export to popular solid modelling systems. The following formats are currently supported:
ACIS
IGES
Parasolid
STEP
C3D
JT
VRML
STL
However, creation of solid models also places additional demands on the system performance. With the lack of operating speed of the program, you can use ”Quick rebuilding of model”. Comparison of modes is indicated in the table below:
| Icon | Mode | Function description |
|
Without rebuilding | Model rebuilding is not performed during changes. This mode is recommended for use with similar editing operations in the number of components. |
|
Accelerated model generation | In edit mode a solid model is built with some simplifications. Some components are displayed through OpenGL (bolts, heat exchanger tubes, trays, etc.). Reinforcement pads of nozzles are created by cylinder projecting, which at visualization may give significant distortions for tangential nozzles. For model rebuilding, an additional memory is required (500-1000 MB, depending on the model complexity). This mode is recommended for use for developing and editing of middle complexity models (50…100 components). |
|
Fine model generation | At editing, the solid model is built with maximum level of detail, reconfiguration may take a significant amount of time. All components are created as solid ones, with holes, fillets, etc. Reinforcement pads of nozzles are created by offset of the intersection line equidistant along the shell, which requires additional calculations. This mode may require additional memory (1-2 GB, depending on the model complexity). This mode is recommended for simple models editing.. |
Note: At calculation or export, the model will be automatically rebuilt in precise mode, if it hasn’t been activated earlier.
