To Create a D1 x D2 Conic Round
1. Create a constant round and keep the Round tab open.
2. Click the Sets tab.
3. In the cross section shape box, select D1 x D2 Conic. The system does the following:
◦ Adds a conic parameter handle with a default value to the current radius for the round set.
◦ Displays the Conic Parameter box on the Round tab and on the Sets tab.
◦ Displays two distance value boxes on the Round tab and in the radius table on the Sets tab.
4. To define the conic parameter that controls the sharpness of the conic shape, drag the conic parameter handle to the preferred value. The system displays the radius value in the graphics window and dynamically updates the preview geometry.
If you set the ratio_grid_interval configuration option to a value from 0 to 1, the conic parameter handle automatically snaps to the grid in intervals of the specified value when you drag this handle.

 You can also type a new parameter or select a most recently used one using the Conic Parameter box on the Round tab or on the Sets tab. |
5. To define a radius, drag each radius handle to the preferred distance or snap each handle to a reference. The system displays the distance values in the graphics window and dynamically updates the preview geometry.

You can also type a new value in the distance value box or select a most recently used value from the list in the radius table ( D1 and D2 columns) located on the Sets tab. The same method applies to the two distance value boxes on the Round tab.

6. To reverse the conic distances, click
on the
Round tab. Click it again to return to the original distance. You can also place your pointer over the radius handle, right-click and choose
Flip on the shortcut menu.
