Sphere

In this Task 

The profile at the base of the object will be projected to the top face of the object.

A sphere will be drawn on the top of the extrusion, using the center of the projected profile.

Associated Tasks 

Inserting a double point circle to create a convenient center point.

Changing the radius of a previously drawn circle.

Before you Start 

View is set to Isometric South East, Workplane is displayed.

Take Note

Some images below are modified for illustrative clarity.

Workplane by Facet

Ribbon : Workspace | Workplanes | WorkPlane | by Facet

Palette : 3D Model | Workplane | Workplane by Facet

Right click in the Editor | Workplane by Facet

This workplane feature applies a workplane to a selected facet (flat surface) of a 3D object.The Page Up and Page Down keys can be used to cycle between the available facets of the solid.

 

Using Workplane by Facet, place the Workplane on the top face of the extrusion, shown below.  Take care to view the model from different viewpoints to check the position of the Workplane before proceeding.

Projection

Ribbon : Draw | Draw 3D | Projection

Default Menu : Modify | Projection

Palette : 3D Model | 3D Object | Projection

This tool projects a 2D profile, either as a single object, or the profile of an extruded 3D object onto a face in a parallel plane.

Make sure the Workplane is seated on the top face of the object as shown below right.

From the menu options above, select the Projection tool and select the profile which is seated on the base of the object shown below left.

Next, select the face onto which the profile should be projected, shown below right.

Profile of 3D object selected (left), face onto which profile is project (right)

The result is shown below.

 

 Change the Radius

Use F7 (or fn F7) to select the most recently drawn object, then right click and select the Edit tool.  TAB to the radius field and input 50.

The result is shown in bold, below.

Take Note

The Selection Info Palette can also be used to change the radius of the circle using Metrics > Radius.

Sphere

Ribbon : Draw | Draw 3D | Sphere

Default Menu : Draw | 3D Objects | 3D Primitives | Sphere

Palette : 3D Model | 3D Object | Sphere

Creates a sphere by indicating a center point and a radius. The radius can either be given by indicating a point in the workspace, or can be input into the radius field of the Inspector Bar.The circumference of the Sphere will always be drawn parallel to the Workplane.

Activate the Globe layer, then use the center of the newly projected profile to insert a Sphere to a radius of 45, shown below.
