- Q1: What is OSNAP in AutoCAD?Ans: OSNAP stands for Object Snap.
It is used to select exact points on objects like endpoints, midpoints, and centers for accurate drawing. - Q2: What is Ortho Mode in AutoCAD used for?Ans: Ortho Mode is used to restrict cursor movement to horizontal and vertical directions only.
It helps in drawing straight lines at 90° angles. - Q3: Name some options present in OSNAP.Ans: Some OSNAP options are:
- ➔ Endpoint
- ➔ Midpoint
- ➔ Center
- ➔ Intersection
- ➔ Perpendicular
- ➔ Tangent
- Q4: How to activate and deactivate ONSNAP?Ans: Steps to activate/deactivate OSNAP:
➔ Press F3 to turn ON/OFF
➔ Or click on the OSNAP button in the status bar - Q5: How to activate and deactivate Ortho Mode?Ans: Steps to activate/deactivate Ortho Mode:
➔ Press F8 to turn ON/OFF
➔ Or click on the Ortho button in the status bar - Q6: What are User Coordinate Systems in AutoCAD?Ans: User Coordinate System (UCS) is a movable coordinate system.
It allows users to define their own origin and directions for drawing. - Q7: What is the Absolute Coordinate System in AutoCAD?Ans: The Absolute Coordinate System uses a fixed origin point (0,0).
All points are defined with respect to this origin. - Q8: What is the Relative Coordinate System in AutoCAD?Ans: The Relative Coordinate System defines points based on the last point entered.
It uses the format @x,y. - Q9: What is the Polar Coordinate System in AutoCAD?Ans: The Polar Coordinate System defines points using distance and angle.
It uses the format @distance<angle. - Q10: What is the Direct Distance Entry System in AutoCAD?Ans: Direct Distance Entry is a method where the user specifies direction and then enters distance.
It is used for quick and accurate drawing. - Q11: What is the Dynamic Input Setting in AutoCAD?Ans: Dynamic Input shows command prompts near the cursor.
It allows users to enter values directly on the screen instead of the command line. - Q12: What is the Cartesian System in AutoCAD?Ans: The Cartesian System is a coordinate system that uses X and Y axes.
It defines positions using horizontal (X) and vertical (Y) values. - Q13: What is PAN in AutoCAD?Ans: PAN is used to move the view of the drawing without changing its position.
It helps in navigating different areas of the drawing.
