Add continued, baseline, and aligned dimensions

00:04

To place a dimension that continues from the right end of that dimension.

00:08

Right click and select continue from the shortcut menu.

00:14

The program prompts you to select the first extension line origin to continue,

00:19

select the extension line on the right.

00:22

The program then prompts you to specify the second extension line origin.

00:27

First on the status bar, expand the object snap tool.

00:32

Make sure the end point and center object snap modes are selected

00:38

and then toggle on object snap,

00:41

then snap to the right end of the horizontal line.

00:46

The command remains active so you can place another

00:49

dimension continuing from the end of the previous dimension.

00:53

Snap to the right end of the diagonal line.

00:58

The command remains active and is still in continue mode

01:02

to return to the default mode. Press enter twice.

01:07

Now the program is again prompting you to

01:09

select objects or specify the first extension line origin

01:14

to place a dimension indicating the distance from the center

01:17

of the hall to the bottom of the object.

01:19

You will need to specify points

01:22

snap to the lower left corner as the first extension line origin.

01:27

The program then prompts you to specify the second extension line origin

01:32

snap to the center of the circle.

01:35

The program initially displays a preview of

01:38

the dimension between these two points.

01:41

But when you move the cursor to the left, the preview changes

01:45

once you see a vertical dimension

01:47

and it is positioned where you want it,

01:49

click to place the dimension

01:53

to place a baseline dimension,

01:55

right click and select baseline from the shortcut menu.

01:60

The program then prompts you to specify the

02:02

first extension line origin as the baseline,

02:05

select the lower extension line.

02:09

The program then prompts you to specify the second extension line origin

02:13

snap to the end point at the top of the leftmost vertical line,

02:18

the command remains active. So you can place another baseline dimension

02:23

snap to the top left corner of the object

02:27

with the command still active

02:29

to return to the default mode. Press enter twice

02:35

to place a dimension measuring the length of the lower diagonal line,

02:39

hover the cursor over the line until you see the dimension preview

02:43

and then select the line,

02:45

then move the cursor away from the line.

02:48

If you move the cursor down the preview changes to a horizontal dimension,

02:54

when you move the cursor to the right, the preview changes to a vertical dimension.

02:59

But when you move the cursor to near the middle of the dimension preview,

03:03

the dimension becomes aligned with the object.

03:06

Once the dimension is positioned where you want it

03:09

click to place the dimension,

03:12

the command is still active

03:14

and you can continue to place additional linear dimensions.

03:19

When you hover the cursor over the circle, notice that the preview changes.

03:24

So you can also place diameter and radial dimensions.

03:28

You could even place an angular dimension

03:31

when you are finished. Placing dimensions press enter or escape to end the command.
