Frequently asked

Questions about working
with AptoCAD.

AptoCAD Mechanical handles machine design, manufacturing, and industrial automation - physical machinery and moving systems. AptoCAD Civil handles structural design, drafting, and construction engineering - the built environment. Both operate to international standards, but serve different needs. If you're unsure which fits, send a general inquiry and we'll point you to the right team.

Yes. Some projects need both - for example, a piece of industrial machinery that requires a structural foundation or mounting framework. Because both departments are part of AptoCAD, we coordinate internally so you get one point of contact and a unified delivery.

Yes - we serve clients across the US, EU, and Asia. We work to international standards (ASME, ISO, IEC for mechanical; relevant structural codes for civil), deliver in your preferred file formats, and operate under NDA on all projects.

Send an inquiry through the form above, or email hello@aptocad.com with your project details. We'll respond within 24 hours with scoping questions, an indicative timeline, and next steps. Detailed projects may include a short discovery call before we provide a fixed-price quote.

We're based in Sri Lanka and serve clients globally. Our combination of internationally-trained engineers and competitive rates is central to what we offer - high-standard engineering delivered cost-effectively, with documented quality at every step.
