6.1.C Creating Forms by Blending, Revolving, and Lofting

Workflow

Demo

Practice Exercise (Optional)

• Create a form by blending two profiles.
• Open the Level 1 plan view.
• Sketch a profile for the bottom of the form.
• Open the Level 4 plan view.
• Sketch another profile for the top of the form.
• Open the 3D Masses view.
• Select both of the profiles, then use the Create Form tool to blend these two profiles into a 3D form.
• Create another form by revolving a profile around an axis.
• Open the Level 1 plan view.
• Open the Reference Plane tool (Architecture > Work Plane > Ref Plane), and create a vertical reference plane for sketching the profile and axis of revolution.
• Select the new reference plane and name it Sketching Plane for Revolution.
• Open the 3D Masses view.
• Use the Set Work Plane tool and pick the Sketching Plane for Revolution by name.
• Use the Show Work Plane tool to show this work plane and make it easier to sketch upon it.
• Sketch a line on the work plane that will serve as the axis of revolution.
• Sketch additional lines on the work plane that define the profile to be revolved around the axis.
• Select the axis and the profile, then use the Create Form tool to create a revolved form.
• Create another form for a multi-story tower by lofting several profiles.
• Open the Level 1 plan view.
• Sketch a profile for the bottom of the form.
• Open the Level 3 plan view.
• Sketch another profile for an intermediate level of the form.
• Open the Level 5 plan view.
• Sketch a third profile for another intermediate level of the form.
• Open the Level 7 plan view.
• Sketch a fourth profile for the top level of the form.
• Open the 3D Masses view.
• Select all four of the profiles, then use the Create Form tool to loft these four profiles into a 3D form representing the shape of your proposed tower design.
