In this Task

• A domed surface will be applied to the top of the extruded circle.

Associated Tasks

• Using the Ambiguity PopupThe Ambiguity popup present choices of all objects within the pick region, allowing the user to select the correct part, face or object. The display of this popup is controlled using Preferences > Select > Enable Ambiguity Popup. It allows a choice between Parts and Curves when multiple objects are in close proximity. to select parts.

Before you Start

• The view is set to an isometric view.

Take Note

• Parts are arbitrarily named when they are created. The names can be changed using the Inspector. They can be changed by right-clicking on the Part Name and inputting a new Part Name.

BLend Edge

Modify | Solid Feature | Blend Edge

The Blend Edge tool is used to create a transitional radial surface by defining a radius and setback value.

Material is either added to, or subtracted from the volume of the solid depending of the radius and setback values.

Options :

Parts

At present, two separate components form part of the model. By selecting near the two intersecting parts, the popup shows two distinct parts. As can be seen in the illustration below, the cylinder is highlighted. By moving the cursor to the bottom part of the model, the extruded base will be selected.

To combine two separate components into one unified part, the boolean functions are used.

Boolean Functions

Boolean is the name given to the method of combining or separating objects which intersect or are adjacent.

The first object selected is referred to as the Primary Object ; the second object selected is referred to as the Secondary Object or the Subtracting Unit.

To combine the volumes of the two parts which comprise the model in this task, the Boolean Add tool will be used.

Add Solid

Modify | Solid Booleans | Add Solid

This 3D boolean function combines the volume of 2 intersecting or adjoining 3D solids or surfaces.

---

Select the Add Solid tool from the toolbar or use Modify | Solid Booleans | Add Solid.

Select the two parts in any order. The resulting combined part is shown below.
