Here are few more tricks you can not do without while working with AutoCAD. There are few important settings that are turned off by default, you need to be aware of them, and turn them ON.
It is likely to be slightly different considering the version of AutoCAD you have.
Here we are working with the 2015 version of AutoCAD.
Best settings in AutoCAD
We have seen in AutoCAD tutorial 02 how to disable and enable the Dynamic input. You need to be able to have it displayed in your Status bar because you will need to turn it ON and OFF quite frequently.
Dynamic input displays options, commands and user input in a tooltip near the cursor when you are drawing.

Object Snap (OSNAP)
OSNAP is a tool that ensures precision while drawing. You use this to help you grab points on existing objects.
Options that are important to us right now are: Midpoint, Quadrant, and Tangent. You need to activate them on the list. (Right click on the OSNAP icon to have the list displayed like on the image above)
Midpoint will help you achieve figures similar to the following.
To draw the segment BA, we needed to know exactly where the middle of DE was. when Midpoint is activated, we just have to hover the cursor close to the center of DE after activating the LINE command for AutoCAD to help us snap the start-point at the center of DE.
Notice the Green triangle indicating the middle of the line.
Quadrant will be essential while working on the following example. You need to be able to hook A, B, C and D on right points.
Tangent will be useful if you have the following to draw.
Just for the sake of knowing, Grid displays a series of graph paper style lines that can serve as a distance of reference.
You should know that at the beginning of every project, you need to set the unit in which you will be drawing. To access it, simply
- Type UNITS
- Hit ENTER
You can use the LENGTH section to set the format for units of measure. For example, if you choose Engineering and Architectural formats, AutoCAD will assume that each unit represents one inch.
You can as well set the Angle format.
Insertion scale helps control the unit of measurement for blocks that are inserted into you drawing. It is recommended to select Unitless to be able to insert blocks without scaling them to match the specified units.
We’ve gone through all features needed at this point and will always come back to add more as the need occurs.
