    So what is wrong with opening work created in educational copy of AutoCAD?

    There is no rational reason to draw this in 2D isometric. Your professor is stuck in the mud. I am very very good at 2D isometrics but this would take me several hours while I could do as 3D and flatshot an isometric in a fraction of that time. Time is money. Does the professor have you do calculations by slide-rule as well?

    New Y14.41 Digital Product Definition standard uses isometric dimensionion on 3D solid. I think Pro/E Wildfire 4.0 was the first to impliment this standard.

    I'm not taking the chance of infection by the "educational" virus. Overly careful, I know.

    There IS a rational reason if it is a required part of a course; to gain a pass certificate.

    I agree there is no other good reason - that's why I modeled it before even thinking about drawing an isometric view.

    I just want to emphasize to those who are not experienced with AutoCAD that there is absolutely no way to "infect" other files unless they use part of the edu content in their work. It is a common misconception that opening an edu file will cause the edu banner to appear on other work.

    Simply open the file, examine the geometry, even save, do anything you want - except use any part of the file for other work. Delete the file after inspection so that someone else doesn't use without understanding the consequences.

    No, it violates the very definition of rational. All the competencies needed to do 2d iso can be demonstrated with a far simpler part (or set of parts). (and yes, I passed a certification that included 2d AutoCAD iso)

    I challenge anyone who thinks this assignment is rational to actually do the 2d iso. This part would be absolute torture in 2d iso.

    Drawings (anything) created with an educational version of acad plot with a banner around the edges - "This was created with an education version of AutoCAD" - or similar.

    If that drawing or any part of it is included in any drawing created with ANY version of acad the same banner is displayed and in any subsequent drawings that acquire anything from that drawing. In other words, it infects anything it comes in contact with therefor it's a virus though that's not what AutoDesk call it (of course).

    The OP presumably wants to pass a course and get a certificate. If the course requires the ability to draw in isometric then the OP has a rational reason to learn isometric projection.
    The fact that the course syllabus includes what might well be considered obsolete requirements is not the OP's fault.
