To Create an Extruded Surface
1. Click
Restyle >
Analytical Surface >
Extrude. The
Extrusion dialog box opens.
2. Click the required check boxes for defining the surface:
◦ Full—Creates an extrusion with a closed section.
◦ Domain—Uses the selected domain for creating and limiting the surface.
3. Select the references for the extruded surface.
◦ Coordinate system—Selects the coordinate system. This coordinate system is used as a reference for manipulating or moving the surface.
◦ Origin point—The point on the base plane of the extruded surface is its origin. For analytical surfaces, if you want to define the origin point before the creation of the surface, you can only select datum points. After creating the surface, to modify the origin point, you can select any location on the facet for defining the origin point.
The surface is translated in the direction normal to the section plane such that in the new position, the origin point of the surface and the selected facet point lie on the same section plane.
Restyle displays the x-, y-, and z-coordinates of the origin point in the respective Origin point coordinates boxes. You can change these to move the origin point, and the surface.
◦ Direction—Selects a datum plane or a planar surface as a directional reference where required. The orientation of the surface depends upon the directional reference.
4. In the Draft angle box, type a value for the draft angle for the surface, if required. You can change the draft angle even after the surface is created. The neutral plane of the draft corresponds to the plane on which the origin resides.
5. Under Direction angular dimensions, change the angle that the revolved surface makes with the direction vectors to rotate the surface in the required direction.
6. Click
to select the created section curve and modify it using Sketcher tools to fit the surface better. After successfully modifying the section, Restyle does not retain any references used for dimensioning or aligning. This means that if you modify the section again, it displays the whole section dimensioned with reference to a coordinate system located over the origin point.
7. Click OK.
