SettingDescription
Height Specifies the height of the form, unless a shape or form above prohibits extrusion. If a shape above only partially blocks extrusion, Height controls the portion of the form that can be extruded past the overlying shape or form. Enabled when the Top > Fixed Height option is selected.
Note: Height extrusion direction is defined by either the Z-axis, perpendicular to the view; or, if AccuDraw is on, by the AccuDraw Z-axis.
Top Controls the geometry and location of the top of a form:
  • Fixed Height — The form has a uniform height as specified in the Height field. The top face of the form is parallel to the bottom face.
  • Connect Shapes — The form is extruded so that it connects to one or more shapes and/or forms. Selecting Connect Shapes displays the Delete Construction check box, which enables or disables the deletion of the limiting shapes and/or forms.
  • Connect 3 pts — The top of the form is located in an imaginary plane defined by three data points.
  • Connect 2 pts/View — The top of the form is located in an imaginary plane constructed through two data points and perpendicular to the view where the last data point is entered.
Delete Constructions Enabled when the Top > Connect Shapes option is selected, limiting shapes and forms are deleted when on.
