FAQ

Questions surveyors ask

Which AutoCAD and Civil 3D versions does Acheck work with?
Full AutoCAD and Civil 3D 2023 through 2027 (not the LT editions). One install covers them all, with a dockable palette editor.
Do I need AutoCAD for the online version?
No. Acheck Online runs in your browser — type the courses and get the same live misclosure, precision ratio and PDF report, with no CAD installed. The desktop version is the one that runs inside AutoCAD and Civil 3D.
Does my drawing or survey data get uploaded anywhere?
The desktop version runs entirely on your own machine and works offline — no upload, no account, no card. You enter your courses and it computes locally.
What’s the difference between the $200 desktop and $15/month online?
Desktop is a one-time, perpetual licence for one computer that runs inside AutoCAD or Civil 3D, offline. Online is a monthly subscription that runs in your browser with no CAD needed — cancel anytime. Both start with a free trial.
Can I try it before I buy?
Yes. Download the 7-day desktop trial (no card, no sign-up), or try the online version free first.
Can I get a refund?
Desktop licences come with a 30-day money-back guarantee — see our Refund Policy. Online subscriptions can be cancelled anytime.
