Model Clipping

Usage Instructions

This tool supports clipping models based on a specified clipping surface. It can be used to obtain model data within a designated range.

Parameter Description

Parameter Name Parameter Description Parameter Type
Model Dataset: Select the source model dataset. DatasetVector
Clipping Surface Dataset: (Optional) Select the polygon dataset that represents the clipping extent. This parameter is mutually exclusive with the Clipping Surface parameter. Please set as needed. DatasetVector
Clipping Surface (Optional) Input a 3D point set representing the clipping surface. This is specified by the output of the 3D Point Set tool. This parameter is mutually exclusive with the Clipping Surface Dataset parameter. Please set as needed. Point3Ds
Constraint Boundary: (Optional) Specify the constraint boundary type. The default value is Consistent With Original Data, meaning the elevation values of the clipped result's boundary match those of the source model data. ConstraintType
Clipping Method: (Optional) A virtual cylinder is generated by extruding along the normal direction of the clipping surface. The region of the model to keep is selected based on this cylinder:
  • Keep Inside: Only the part of the model that intersects with the cylinder is kept.
  • Keep Outside: Only the part of the model that does not intersect with the cylinder is kept.
  • Keep Sides: Only the boundaries where the model intersects with the cylinder's surface are kept. Selecting this mode requires ensuring the model is manifold, with no holes or other issues.
  • Keep Inside And Outside: Keep both the inside and outside parts of the cylinder.
  • Keep Inside And Sides: Keep both the inside and the side parts.
  • Keep Outside And Sides: Keep both the outside and the side parts.
 MeshKeepType
Model Retention (Optional) Set the mode for retaining model data after clipping. Options include:
  • Above And Below Clipping Surface: Both model data above and below the clipping surface are kept as result data.
  • Above Clipping Surface: Only model data above the clipping surface is kept as result data.
  • Below Clipping Surface: Only model data below the clipping surface is kept as result data.
 MeshClipKeepType
Merge Result (Optional) When the clipping method is "Keep Inside And Outside," "Keep Inside And Sides," or "Keep Outside And Sides," checking this parameter merges the corresponding two parts of the result data. Boolean
Target Datasource Select the datasource to save the result model dataset. Datasource
Result Dataset Name Set the name of the result model dataset. String
