1. Once you create surface then a solid how do you go back and edit the original sketch? Editing the original sketch is no longer necessary. SpaceClaim does not keep track of features. Any edits that you need to make to the solid body (which involve the original sketch) can be done using the Pull and Move commands. Click a face and start the Move tool, then translate or rotate in the desired direction. 2. How do you lock a point so you can drag the feature without moving that point? This can generally be accomplished by moving only the desired face(s) on the solid body. Hold Ctrl and click to select multiple items at once. 3. How do you snap to point or feature? You can use the Up To option within the Pull or Move commands. Please go through Pull and Move tutorials for detailed understanding.
