Calculate new endpoints with object snap tracking

00:04

Let's discuss

00:05

object snap tracking.

00:08

This option is extremely useful when you're trying to

00:12

calculate new end points based on existing end points

00:16

in the drawing

00:17

doing this without object snap tracking usually means that the

00:21

designer will offset lines to get to a specific point.

00:25

And then the offset lines are typically erased because they

00:29

were drawn only to assist in calculating a new point.

00:34

As mentioned.

00:36

Without using object snap tracking,

00:38

you would typically have to offset lines and

00:41

erase them to achieve what you're about to see

00:44

is done using object snap tracking. So the first thing we need to do

00:49

is come down to the status bar

00:52

and make sure that object snap tracking is turned on.

00:56

Then in this example,

00:59

I will draw a line

01:01

calculating from the endpoint of this line

01:05

up to the top line here. So in other words,

01:09

in order to do that, you would typically draw a line from this end point

01:14

and have it come up perpendicular,

01:16

then trim that line to the size that you want it to be.

01:20

Instead, what we're gonna do is use object tracking for this.

01:25

So I'm gonna start my line command

01:27

and then instead of clicking the end points, I'm gonna hover over them

01:34

like this without clicking

01:37

and notice how I get a projected green line.

01:41

And as they say, with object snap tracking, X marks the spot,

01:46

I can click to start that line.

01:49

And then if it was to be 10 ft in length, for example,

01:53

now I have just created a 10 ft line

01:57

that lines up with the end point of this line on the opposite side of the building.

02:03

And it was calculated using object snap tracking.

02:07

The nice thing here is no erasing or no trimming needs to be done to accomplish this.
