Select one of the following: Before specifying the dimension line location, you can edit or rotate the text. To get an 1:1 view you also have to scale the view with the factor 1/sqrt(2/3) 1.2247449. To get this result the viewpoint must be rotated 45° in the XY plane and arccos(sqrt(2/3)) 35.26439.° from the XY plane. Yes, isometric view is defined that the lines are 30/150° rotated. To Create an Angular Dimension Click Annotate tab Dimensions panel Dimension. BTW, true isometric angle is not in reality 30. The optional dimension label displays the calculated angle between the two lines. Click the first line at the point where it intersects the second line. To calculate an angle between two lines Click Review tab Measure panel Measure drop-down Angle. How do you find the angle between two lines in Autocad? Newer versions of AutoCAD have an Isoplane icon on the status bar. You can switch between the three ‘isoplanes’ (top, right, left) by using this command or by pressing the F5 key. How do you draw an isometric angle in AutoCAD?ĪutoCAD has a command called ISOPLANE which allows you to easily draw at a 30 degree angle as needed for an isometric drawing. Do one of the following to specify the length: Press the Spacebar or Enter. Do one of the following to specify the angle: Enter the left angle bracket (<) and the angle, for example <45, and move the cursor to indicate the direction.
