Extrude and Push/Pull
Give a drawing shape height, then edit its faces or combine it with other 3D objects.
Extrude gives supported drawing shapes a 3D form. Push/Pull edits a face of an existing object inside Reshape. Stack controls a relationship between objects. Choose the operation that matches the scope of the change: a starting outline, an existing face or two separate objects.
Choose a supported outline
Draw or select the closed shape that should become a 3D object. Switch to the 3D view and choose Extrude. A selected shape must support the requested extrusion.
Set height and the starting surface
Use Height and the available Top Surface choices in the Extrude guide. Enter a positive length in project units or with an explicit unit, then use the offered canvas interaction or Apply. A height of zero does not create a valid extrusion.
Edit the existing object
Open the object in Reshape and choose Push/Pull to move a face. Use Distance, To face or Through all under Ends at where available. A flat face moves along its normal; supported curved faces can be resized. Unsupported cases show a reason.
Combine separate objects
Finish the current focused edit before using whole-object tools. Use Stack for live Build or Dig relationships, or the supported whole-object boolean commands when you want a combined result. These operations have different selection and target rules.
Review and undo
Inspect the result from more than one angle. Undo reverses a committed edit. If an operation refuses the target, change the selection or geometry according to the displayed reason rather than retrying an unsupported combination.
