How to Change the Plane Ind Draw in Autocad
Topics covered in this Lesson:
Isometric Drafting Techniques
Isometic Cartoon
Using Isometric commands is one of the simplest means to give a 3-D representation while using only 2-D commands. This has been the usual style of doing things earlier CAD allowed true 3-D piece of work to be done. Many times an isometric cartoon is used to compliment or give more information to a 3 view orthographic cartoon. See the sample below.
You can run across that information technology is a very simple drawing. This bones isometric drawing of the object gives a very adept thought of what it looks like. If this is all that is needed and so isometric works well. Unfortunately, as soon equally y'all change anything, similar the block's elevation, you'll need to redraw all four views.
AutoCAD has a command called ISOPLANE which allows you lot to easily depict at a 30 degree angle equally needed for an isometric cartoon. You can switch betwixt the three 'isoplanes' (superlative, correct, left) by using this command or past pressing the F5 key.
Command: ISOPLANE <ENTER>
Current isoplane: Correct
Enter isometric plane setting [Left/Tiptop/Right] <Left>: T <ENTER>
Current isoplane: Acme
Newer versions of AutoCAD take an Isoplane icon on the condition bar. Y'all can click this to enter Isometric Drafting Fashion as shown below. You can also change your Isoplanes hither (but F5 is faster).
By invoking this command, AutoCAD is now set to draw on the top isoplane past default. Your other choices would be Left or Right. Your first exercise will be to draw the object shown above using isometric methods.
Exercise i - Isometric Drafting
Begin a new drawing using the acad.dwt template
Create a layer called OBJECT and give it a green colour. Make this your electric current layer.
Type in DDRMODES to bring up the Drawing Aids dialog box. Brand your settings the same as what y'all see beneath (just turn on Isometric Snap).
NOTE :
Recollect this dialog box for subsequently. When you are done with Isometric Drafting, open up this dialog box over again and change the radio button from "Isometric snap" to "Rectangular snap" to get back to the regular drawing settings.
Press OK and y'all'll see that the grid is set up for isometric drawing for the left isoplane in one/2 unit increments. Your crosshairs are at present angled to show you which isoplane you are currently on and the Grid is laid out differently from what you may be used to.
Begin by drawing the left side of the box (shown at the top of the lesson) using the line command. Ignore the pigsty at this betoken. Yous volition want to apply the Directly Altitude Entry Organization for this exercise and make certain that you have Ortho ( F8) and Osnaps ( F3) turned on.
Switch to your right isoplane ( F5) and draw the right side.
Switch to your top isoplane ( F5) and draw the height view.
Create the angle lines to add the angled surface.
Switch back to the left isoplane and start the ELLIPSE command. At the command prompt, press I for isocircle. This will permit you to create an ellipse at the correct angle based on the radius of the circumvolve in the orthographic drawing. Use the Osnap to pick the right eye point.
Save your drawing in your CAD folder. (Y'all have a CAD Folder past now, correct?)
To dimension an isometric drawing, you have to exercise a few things first. Create a text mode called Left, and give it a xxx o obliquing angle, so create some other called right with a -thirty o obliquing bending. Then create a new dimension style that has the text aligned with the dimension line. After you have placed a dimension, employ the DIMEDIT command to change the obliquing angle of the dimension + or - 30 degrees. You may too need to utilise the backdrop to alter the text in the dimension to left or right depending upon the orientation of the dimension.
Keep in heed that this is yet simply 2d. Recall that in some instances, information technology may be quicker and easier to use this method rather than the more than circuitous 3-D methods you'll exist learning in the following lessons.
Extra Practice: Copy this drawing using isometric drawing methods.
Extra Exercise: Copy this drawing using isometric drawing methods. If you lot want to add the hidden lines, bound ahead to Lesson 4-3 to learn near linetypes.

Fun fact: Autodesk, like many other software companies, was challenged by the effects of software piracy in the early 1990s. The company has prevailed in litigation to protect its copyrights, including a 1994 suit against Cadisys Corporation, the result of which was a $100,000 settlement in Autodesk's favor on May 23, 1994.
