Conclusion:

As the above exercise, contain multiple uses of some of the commands like – LINE, OFFSET, and TRIM, etc. but efficiently use of these commands within a limited period saves a lot of time for the designer and project. Other commands like FILLET, TRIM, MTEXT, MLEADER, and COPY are also used in this exercise. This exercise gives good practice for the modeling of the building plan, elevation, and details.
