Once 3D becomes available in even basic drafting programs, and old board drafters like me all fade away, isometrics will fade away too. And representing circles would be a math nightmare….Īfter all that, in short though, Isometrics are a dying art. How you would tweek the snap aspect ratio to get what you are looking for is a whole other ball of wax. (Isometrics even have their own special ellipses used to represent circles – standard ellipses don’t look rightl). Like I said, Isometrics are a very old drawing system so if you go off the 30-330 then you are not truly drawing an Isometric. If, however, I have misunderstood you, and what you are asking is “I like the look but don’t want the 30-330 angles, I want 20-340 angles… you could do that in AutoCAD, but just not with Isometric Snap. If you have never done an isometric drawing in AutoCAD, know that 1) 45 degree lines are represented in isometric drawings as either straight horizontal or vertical lines, and 2) often it is easier to just draw an isometric square then trim off the angled parts. If you need to draw, say, a nut and bolt, then you would have to go off those predetermined angles for the “45 degree lines”. Isometrics do away with this by making all lines that would be x-y plane lines run parallel at 30 degrees or 330 degrees. There are several forms of so called projection, some of which have foreshortening due to drawing lines (that are at 90 to each other – ie: the edges of a table top) ) in what would be the x-y planes to vanishing points. Isometrics are a very old form of “projection” from way, way back.
Drawing curved edges and objects while in Isometric mode will take some practice, so be patient and have fun. the sub-option that you need to select is the “Isocirlce” option. Using this tool while in an active isometric mode will show and extra sub-option in the command line. And to be more specific, use the “Axis, End” ellipse tool. When you need to create a circle, use an ellipse. Isometrics are fun but they are a little difficult when it comes to rounded objects and rounded edges. Shown below is an example of drawing a cube in Isometric mode: To change which Isometric mode you are in, use the F5 function button: To draft so that your lines are aligned with this Isometric mode make sure that ORTHO is turned on. This is showing you that your cursor is in an Isometric mode. Once the dialog box closes you will notice that your drawing cursor (cross hairs) will look funny. Select “Isometric Snap” from the dialog box and then click OK
To turn on the Isometric mode, Right click on the “SNAP” button that is in the Drafting Settings buttons. The Isometric planes are basically increments of 30 degrees and shown below: The picture below shows the flat Iso-drawing when the view is rotated to a 3D view as shown by the rotation of the viewcube: You can see this by looking at your view as it is shown in the viewcube. Notice below, that when drafting in an Isometric plane, you are still drawing in the flat 2D plane.

It is because these lines do not diminish into the horizon that they remain at full sclae and are therefore measurable. An Isometric drawing therefore contains lines that remain paralell to each other. This means that even AutoCAD LT can draw 3D representations.Ī) A pictorial representation of an object in which all three dimensions are drawn at full scale rather than foreshortening them to the true projection or vanishing point. AutoCAD has an isometric drawing mode that lets you drawing 3D-looking objects in 2D just like when you draw 3D objects on a flat sheet of paper.
