Hatches can be introduced to drawings via drawing style (drawing rules). Hatches are available for sections and plan views for Position defined as Section.
The line type and pen width can also be defined for a particular drawing rule with hatching. Hatching style is available in a combo-box “style”. The user can select from available hatching styles which are predefined by Hatching style manager.
Hatching styles can be added / deleted / modified in the Hatch style manager. It is a standard database manager with all standard functions.
When some kind of hatch is used in a PSE, then it cannot be deleted.
Properties:
- Scale: overall scale of hatch pattern
- Hatch definition script: enables to modify the script pattern (see further for syntax)
- Size X, Size Y: defines the size of basic hatch pattern
- Offset X, Offset Y: the offset of script pattern origin (0;0 coordinate from the script is moved)
- Hatch rotation: rotation of hatch pattern with respect to the LCS of the plane section entity
The shape of the hatch is defined by the script with simple syntax – Hatch definition script:
