Wireframe Split

Split a wireframe using a plane

Wireframe Split

To access this dialog:

  • Activate the Surfaces ribbon and select Operations | Plane | Split

  • From the Command line, run the wireframe-split command.

The wireframe Split dialog splits a selected wireframe object into two along the intersection of a defined plane.

Note: This command supports flexible wireframe selection.

Field Details:

Object: either choose a loaded wireframe Object (the default is the current object) or selected wireframe triangle data (Selected triangles). You can select triangle data whilst the Multiple Section dialog is open.

Key Field: select a key field if required, or leave at the default <None> setting. Each keyfield value will be processed separately and the output wireframe data will include the keyfield value.

If multiple object data is selected, only data columns common to all selected objects will be listed.

Plane Orientation: provides the tools for defining the orientation of the  plane against which the wireframe object will be split.

  • Horizontal: sets the plane to be horizontal (i.e. both Azimuth and Inclination are 0 degrees).

  • North-South: sets the plane to a vertical North-South orientation (i.e. Azimuth is 90 degrees and Inclination is -90 degrees).

  • East-West: sets the plane to a vertical East-West orientation (i.e. Azimuth is 0 degrees and Inclination is -90 degrees).

  • 3D Section: if any sections have been defined in the active 3D window, these planes can be used to section the selected wireframe object. Click this button to transfer the azimuth and dip of the section to the relevant fields. If no section data has been defined, this option will be unavailable.

  • Azimuth: sets the azimuth of the plane. Note that this field is automatically updated when either of the top four options are selected.

  • Inclination: sets inclination of the plane. Note that this field is automatically updated when either of the top four options are selected.

Use View Plane: fixes the plane as the current view plane in the design window.

Pick Face: activates the picking tool to allow the selection of a single wireframe face. The azimuth and dip will correspond to those of the face and the reference point will have the coordinates of the selected point.

Plane Reference Point: identifies a single point which will fix the plane in space.

  • X: displays or sets the X coordinate (northing) of the reference point.

  • Y: displays or sets the Y coordinate (easting) of the reference point.

  • Z: displays or sets the Z coordinate (elevation) of the reference point.

Output:

  • Single Object Output: selected by default, this check box determines whether a single wireframe object is created, containing multiple objects, one for each distinct wireframe volume generated.

    You can output data either within the Current object, an existing wireframe object (pick it from the list) or a new object (type a new name).

  • Multiple New Objects: this will output a new string object for each section string that is generated. Each object will start with the defined Prefix (followed by an index number, starting at zero).

  • Cap Ends: when selected, closes the open ends of a sliced solid wireframe. In effect, a closed object is created.

  • Split Column: if you are generating a single object as a result of the command, this object can have an optional, additional field representing the section index that each wireframe entity is related to, within the object. You can use this box to either a) enter a new column definition that will be added to the resulting object, containing an automatically-incremented section index, relevant to each entity, b) select an existing field description from the drop-down list (generated from the descriptions found in the original wireframe file) or c) leave the field set to [none] in which case no section index will be output.
