Mechanical) in SolidWorks?

Short Answer

Yes — in SolidWorks, the fastest professional way to create a mechanical section view is with Section View in a drawing or model display. It lets you cut through parts and assemblies using a plane or face to expose internal features clearly. Limitation: section views do not physically modify the model geometry.

What You Need to Know Before

Warning: If your assembly has unmerged bodies, misaligned components, or excluded fasteners, the section may look wrong even though the model is correct. A very common failure is cutting with the wrong plane orientation, which produces a misleading mechanical section for manufacturing review.

How to Create a Mechanical Section in SolidWorks

• Command: Section View

• Shortcut: None by default

• Quick Steps:

  1. In a part or assembly, go to the Heads-Up View toolbar or View > Display > Section View, then click Section View.
  2. In the PropertyManager, select a section plane, planar face, or reference plane to define the cut.
  3. Turn on a real option such as Section Cap or adjust the Offset Distance, then confirm to display the mechanical section.

Variables & Settings

• Key Setting: Section Cap

• Expert Setting: This option fills cut faces so the section reads clearly in shaded views. In mechanical review workflows, keeping Section Cap enabled makes internal cavities, wall thickness, and interference zones much easier to interpret.

Why it Fails

• Cause 1 (Geometry): The selected plane does not pass through the internal feature you actually need to show, so the section appears empty or incomplete.

• Cause 2 (layers/Locks): In drawings, components or bodies may be hidden, suppressed, or excluded from display states, making the section look incorrect.

• Cause 3 (Command/Logic): Section View is only a visual cut in the model environment; users sometimes expect it to create editable sliced bodies or true manufacturing geometry.

Quick Fix & Best Practice

• Quick Fix: Edit the Section View definition and reselect a proper reference plane or apply an Offset Distance so the cut passes through the required internal feature.

• Manager’s Verdict: Use Section View for design review, internal inspection, and drawing communication. Avoid relying on it when you need actual split geometry—use modeling features like Split instead.

FAQ

Can I create a section in a solidworks drawing?
Yes, use Section View from the drawing view tools to generate a section from an existing view.

Can I section only one part in an assembly?
Yes, by adjusting section scope or excluding components in the section settings.

Does Section View change the real part model?
No, it is a display and documentation tool unless you use a separate modeling feature like Split.
