An explanation of fields and properties

Wireframe Split by String

To access this dialog:

  • Activate the Structure ribbon and select Operations | Plane | Split by String

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

A string must be selected before this command is run. Please see here for important information considering the type of string that can be used.

 

The Split By String dialog is used to split a wireframe (or preselected wireframe triangle data) into two or more parts using the selected string and defined projection parameters.

The cutting string must be able to create an intersection plane, when projected in the selected direction, to subdivide the wireframe data completely i.e. it should extend beyond the limits of the wireframe.

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 dialog is open.

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 section planes can be used to generate section strings. 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 3D window.

Pick Face: click this button, then select a wireframe face in the 3D window. The Azimuth and Inclination 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.

Section Spacing: sets the separation of the parallel planes starting from the defined plane.

Output:

  • Single Object Output: selected by default, this check box determines whether a single wireframe object is created, or if independent wireframe objects (each representing a single wireframe 'split') are created.

    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).
