How to stretch or pull one side of a 3D model in Autodesk Fusion?

ByCADbrief Staff

Short Answer

Yes — in Autodesk Fusion, the most common professional way to stretch or pull one side of a 3D model is with Press Pull on a selected face. This moves the face by a set distance and is the fastest method for simple direct edits on solid bodies. Limitation: it may fail on complex or heavily constrained geometry.

What You Need to Know Before

Warning: Press Pull can change adjacent faces and connected features in ways that are not obvious at first, especially on filleted or tapered geometry. If the body was built from parametric features, a direct face edit can also create timeline complications later.

How to Stretch or Pull One Side of a 3D Model in Autodesk Fusion

  • Command: Press Pull

  • Shortcut: Q

  • Quick Steps:

    1. Press Q or go to the Solid tab > Modify panel > Press Pull.
    2. Click the face on the side of the 3D model you want to stretch or pull.
    3. Enter the distance value, set Direction if needed, then confirm with OK.

  • Use the face manipulator for drag control, or type an exact value for precision.

  • Real setting: use the New Offset option when Fusion treats the selection as an offset face operation.

Variables & Settings

  • Key Setting: Distance / New Offset

  • Expert Setting: This value controls how far the selected face moves. A positive value typically extends the body, while a negative value pulls it inward. For accurate edits, enter a numeric value instead of dragging the arrow.

Why it Fails

  • Cause 1 (Geometry): The selected face is tied to surrounding fillets, draft, or complex topology that cannot be offset cleanly.
  • Cause 2 (layers/Locks): The body or component is inactive, linked, or read-only, so the face cannot be edited directly.
  • Cause 3 (Command/Logic): You selected a sketch profile or unsupported geometry type instead of a solid face, so Press Pull behaves differently or fails.

Quick Fix & Best Practice

  • Quick Fix: Activate the correct component, remove or suppress problematic fillets if needed, then rerun Press Pull on the main solid face.
  • Manager’s Verdict: Use Press Pull for fast, local size changes during concept edits or late revisions, but avoid it when the model should be changed cleanly through the original sketch or feature parameters.

FAQ

Can I pull multiple faces at the same time?

Yes, if the selected faces can offset together without breaking the solid.

Is Press Pull the same as Extrude in Fusion?

No, Press Pull edits existing faces, while Extrude usually creates or modifies geometry from a sketch or profile.

Should I edit the sketch instead of using Press Pull?

Yes, if the model is fully parametric and you want the most stable long-term result.
