Set to Isometric

In AutoCAD 2000 or higher, right-click the SNAP toggle in the Status Bar.

Select (x) Grid snap and (x) Isometric snap

You could also type SNAPSTYL and set it to "1"

Now, set the (x) Polar snap on and set the Polar Spacing. If you think you will beusing the grid, set the Grid Y spacing to the same number.

Under the Polar tab, set [x] Polar Tracking On and select the Increment angle 30degrees from the list.

(x) Track using all polar angle settings and (x) Absolute.



Try to draw a box like this:

Change the Isometric Plane

In AutoCAD, use [F5] to toggle through the isometric planes.In the picture above, you see the cursor set to the <Isoplane Right> setting.

The crosshairs will switch to the different sides of an imaginary box. You will alsosee which isoplane you are on from the messages that appear on the command line

and by the cursor crosshairs. If you imagine the crosshairs being the centerline of a circle, which side of the box would the circle be on?

Draw an Isometric Circle



To draw a circle in Isometric, start the EL Ellipse command. While you have theIsometric Snap turned on, AutoCAD gives you an additional selection of "Isocircle".

For greater accuracy in placement, turn OSNAP MIDpoint, ENDpoint and OTRACKOn.

Command: EL ELLIPSESpecify axis endpoint of ellipse or[Arc/Center/Isocircle]: I

Specify center of isocircle: <Pick Point>

Specify radius of isocircle or [Diameter]: <Pick

Point>

Command:

The isocircle will align itself to the Isoplane side that is currently active.

Drawing a vertical tank is done with isoplane top active.

You may have to switch to another isoplane before copying the top and drawing thevertical lines.



Draw Iso Text

In AutoCAD, start the ST Style command and create two text styles... ISO30 and

ISO-30. Set the angle of ISO30 to 30 degrees (positive). Set the angle of ISO-30to -30 degrees (negative).

Start the DT Dynamic Text command and start typing your label. You will have torotate the text into position. Once you create a correct label, you can use MAMatch Properties to copy the rotation and text angle to a plain piece of text.

To draw Isometric Dimensions

To create isometric dimensions in AutoCAD, you need to first use DDIM to create adimension style for ISO1 and ISO2 (or ISORight and ISOLeft, etc). Assign these

two dimension styles the text styles you created earlier (ISO30 and ISO-30). See"Draw Isometric Text" above.

The two styles ISO1 and ISO2 will alternate around the box, and the text should bealigned 30 degrees to the right then 30 degrees to the left.



Now, start the DAL Dimaligned command and type in all the responses you seehere:

Command: <Osnap on> (set to ENDpoint)

Command: DDIM (set to ISO1 dimension style)

Command: DAL _.dimalignedSpecify first extension line origin or <selectobject>: <P1>

Specify second extension line origin: <P2>
