I'm looking for a course specific to land surveying using a Mac. I'm currently taking a general course on Udemy which has been a good introduction to the very basics. The course is taught on PC which has been a minor challenge. I'm wanting to learn to use AutoCAD for land surveying specifically. I have only 12 days left of my free trial so I'm wanting to learn as much as possible quickly and affordably. Thank you for your reply.
