- Q1: What is Extrude Command in AutoCAD?Ans: The Extrude Command is used to convert a 2D shape into a 3D solid by giving it height or depth.
It adds thickness to flat objects. - Q2: How do you extrude an object in AutoCAD?Ans: Steps to extrude an object:
➔ Select the 2D shape
➔ Type EXTRUDE and press Enter
➔ Specify height or direction
➔ Press Enter to create 3D solid - Q3: What is Revolve Solid Command in AutoCAD?Ans: The Revolve Command is used to create a 3D solid by rotating a 2D shape around an axis.
It is used for circular objects like bottles or cylinders. - Q4: How do you revolve an object in AutoCAD?Ans: Steps to revolve an object:
➔ Draw a 2D profile
➔ Type REVOLVE and press Enter
➔ Select the object
➔ Specify axis of rotation
➔ Enter angle (usually 360°) - Q5: What is Sweep Solid Command in AutoCAD?Ans: The Sweep Command is used to create a 3D solid by moving a 2D shape along a path.
It is useful for pipes, wires, and curved objects. - Q6: How do you sweep an object in AutoCAD?Ans: Steps to sweep an object:
➔ Draw profile shape
➔ Draw path curve
➔ Type SWEEP and press Enter
➔ Select profile
➔ Select path - Q7: What is Loft Solid Command in AutoCAD?Ans: The Loft Command is used to create a 3D solid between multiple cross-sectional shapes.
It creates smooth transition surfaces. - Q8: How do you loft an object in AutoCAD?Ans: Steps to loft an object:
➔ Draw multiple profiles
➔ Type LOFT and press Enter
➔ Select all profiles in order
➔ Press Enter to create solid - Q9: What is Union Command in AutoCAD?Ans: The Union Command is used to combine two or more 3D objects into a single solid.
It removes internal overlapping parts. - Q10: What is Subtract Command in AutoCAD?Ans: The Subtract Command is used to remove one object from another.
It is used for creating holes or cut-outs. - Q11: What is Intersect Command in AutoCAD?Ans: The Intersect Command is used to create a new solid from the overlapping area of objects.
Only the common part is kept. - Q12: Name the Boolean Operations used in AutoCAD.Ans: Boolean operations in AutoCAD are:
- ➔ Union
- ➔ Subtract
- ➔ Intersect
- Q13: What is Solid Modelling in AutoCAD?Ans: Solid Modelling is the process of creating and editing 3D solid objects in AutoCAD.
It helps in designing realistic and accurate 3D models.
