Advanced properties define the extents and attributes of the section viewport. Specify them when the viewport is created, or after the viewport has been created; edit the properties from either the Object Info palette or the Properties dialog box.
Finite sections are useful when you want to create interior elevations. For example, draw a section line across a particular room of a building, and set the layer visibility only for the room’s floor to create an interior elevation of only that room. For an even more precise interior elevation, use a clip cube to create the section viewport; the extents are automatically set according to the clip cube’s shape.
The X, Y position of perspective vertical section views is at the center of the section line. The Z position depends on the height range selection (finite or infinite).
To specify the advanced properties of a section viewport:
1. From the Create Section Viewport dialog box or Create Horizontal Section Viewport dialog box, click Advanced Section Properties.
Alternatively, select the viewport, and then from the Object Info palette or the Properties dialog box, click Advanced Properties.
The Advanced Section Properties/Advanced Horizontal Section Properties dialog box opens.
2.For vertical section viewports, click the Extents tab to specify either an infinite section view, or the length, height (elevation), and depth of a finite vertical section viewport.
Extents for horizontal section viewports are managed from the Cut Plane and Extents dialog box; see Setting horizontal section viewport cut planes and extents).
Click to show/hide the parameters.
3.Click the Attributes tab to specify the appearance of objects on and beyond the section plane. Objects on the cut plane can maintain an individual profile, or can be divided into structural and non-structural groups to display them differently according to class settings.
Certain 3D objects can be designated as structural by selecting Merge with Structural Objects in Sections from the Object Info palette. This allows their appearance to merge with other structural objects on the section plane. Merged objects display as a single unit with one continuous fill.
Objects that can be designated as structural |
|
Deforms (generic solid) Multiple extrudes Chain extrudes Cylinders (extrude) Extruded polygons (mesh) Subdivisions Sweeps NURBS surfaces |
CSG solids (add/subtract/intersect/section) Extrudes Extrude along paths Tapered extrudes Extruded rectangles (extrude) Meshes Solids (sphere/cone/hemisphere) Stair structures (top face, bottom face, front face, inside/outside) |
Click to show/hide the parameters.
4.Click the Display tab to specify the section viewport display properties.
