Wire diagram which is so cluttered by layers that for $9.99 you can’t filter, adjust perspective or render. Baiting you into paying more for a full featured viewer which for all intents and purposes should be FREE given you already paid $100 for the software. No thanks will just you laptop version. Disappointed IMSI really disappointed ### 5/5 — Thank You, IMSI *2014-09-10, version 3.5* I loved the free version and I didn't mind the banners. I only paid for the X version as "thank you" to IMSI for making a great app -- it's spins, zooms, etc very quickly! I'll be saving a ton on ink and paper with this. Thank you, IMSI! It's very nice to experience a quality app like this. ### 1/5 — Terrible *2013-05-23, version 2.1.1* Don't waste your money, this app does nothing! ### 1/5 — Don't Buy for IPhone 5 *2013-05-23, version 2.1.1* Bought to open email attachments (dwg). Does not work. Waste of money. ### 5/5 — Good enough *2013-02-02, version 2.1.0* This is the best app i found for viewing dwg files ! ### 5/5 — Engineer/Designer *2012-07-10, version 2.0.2* Turboviewer x is by all means the best & fastest AutoCad drawings Viewer . I highly recommend it for every one that use Ipad to review drawings at site. It really helps get rid of plans & paper. It is fast as its name implies. ## Frequently asked questions about TurboViewer X ### What file types does TurboViewer X support?
