Autocad | Rotating and scaling scanned layout plan using carpark lot alignment as reference

Hi Everyone. Today, I will be showing you how to scale a drawing with a carpark lot on plan. A carpark lot is 2.4m x 5.8m. So, if you have a scanned plan which is out of scale, you can use this method to scale it.

First, you need to draw a horizontal line so that you can use it as a reference line to rotate a carpark to align with the line. This will make scaling easier and more accurate. Ok! Let us draw a 5800 mm length line from this base point at a carpark corner. Then we will rotate the car park and scale it next draw a line that has the same angle as the carpark lot.

It is slightly slanted so turn off your “ORTHO”.

Then we will rotate the line and the plan to match the horizontal line. So “R” “O” Enter. Select the plan and select the line. Then click on the base point. “R” Spacebar. “R” means reference. Then click the base point again. Click the edge and click the end of the carpark lot line. Then hover it on top of this line and click. There we are we have rotated the whole thing to align to our reference line.

Now, we need to scale it up so that the side of the.. the length of the carpark lot is the same as our reference line which is 5800mm so “S” “C” enter or “S” “C” spacebar. Then click on the base point then “R” enter and “R” means reference. Then click on the end of the carpark lot. Then we want the end to be at the end of our reference line so click the second point. There it is. We have scaled the plan successfully. That’s it!
