In as much as the recipient is using their browser to view it and NOT a true PDF viewer. I have the same problem here (University). I'll email a PDF to someone and they get back with me that they can't zoom in enough or that the image quality is horrible. I ask them if they are using their browser to view the PDF? 99% of the time they are and it fixes the issues when I show them how to download it and then open it.

What "free" version of AutoCAD have you been using? Are you going to be doing this with a company or as a sub-contractor for a builder? Well for one you can't "buy" AutoCAD anymore, you have to lease it through subscription. Which means that if you stop paying the yearly subscription you lose access to the software. If it was me I'd sign up for the Revit LT Suite. This way you'd get Revit LT and AutoCAD LT to use. Revit LT Of course there are other options such as BricsCAD, NanoCAD, TurboCAD and other AutoCAD type software that allow full purchase.

There is no "free" version of AutoCAD, unless you are talking about the educational version. If so, what are you using now? AutoCAD or AutoCAD LT? Before deciding, you might want to check out BricsCAD, which is available as a perpetual license (you own it), while AutoCAD and LT can only be rented (you stop paying, it stops working).
