Built for New Jersey civil engineers

Your CAD team rebuilds the same details every project. We generate them in 30 seconds.

CivDraw is a parametric DXF generator for civil land development. Define your parameters, get a standards-compliant drawing. Open it in AutoCAD. Refine and submit. Every dimension follows NJ RSIS, NJ DOT, AASHTO, and ADA. Verified, not guessed.

Free tier: 50 drawings/month. Pro: $99/mo.

The problem

Standard details shouldn't take hours

Every NJ civil project needs the same drawings. Typical sections, parking layouts, utility trenches, E&SC details, title blocks. Your CAD designers rebuild them from scratch or copy from the last project and hope they remembered to update every dimension.

That's how a 9-foot parking stall becomes 8'6". How a Type B curb shows up where a Type E belongs. How the ADA count is wrong because someone forgot to update it when the stall count changed. Your PE catches it in QC review. Or worse, the municipality catches it.

CivDraw eliminates this entire class of error. The dimensions are computed from the standards, not typed by hand. If the stall count is 30, the ADA count is always 2. If the road is a collector, the lane width is always 12 feet. The math doesn't make typos.

How it works

Three steps to a DXF you can submit

Choose your drawing type

Pick from 11 civil drawing types. Fill in the parameters: road width, stall count, pipe diameter. Smart defaults pre-fill NJ-standard values so you start from a correct baseline.

Preview and adjust

See the drawing update as you change inputs. Warnings flag anything outside standard ranges before you generate. No surprises when your PE reviews it.

Download DXF, open in AutoCAD

Get a production-ready DXF with correct NCS layers, dimensions, hatching, and annotations. Opens clean in AutoCAD, Civil 3D, BricsCAD, or any DXF-compatible tool. Add your site-specific details and submit.

Pro users can skip the form. Describe what you need in plain English and AI extracts the parameters for you.

Engineering standards

Every dimension traced to its source

CivDraw doesn't guess dimensions. Every value is encoded from the governing standard and tested with a source citation. When we say a parking stall is 9 feet wide, we can point you to NJ RSIS Section 4.4 Table 4.4. When we set a curb face height to 6 inches, that's NJDOT Standard Detail CD-607. Not an approximation. The actual published value.

Your CAD team works on site-specific design. The work that actually requires judgment.

One caught dimension error per quarter pays for a year of Pro. One fewer round of municipal review comments pays for a decade.

For developers

CAD generation as an API

CivDraw is API-first. Every drawing type is available as a REST endpoint. Generate drawings programmatically, plug it into your project management pipeline, or batch-process an entire subdivision's worth of details. Your API key works with any language. Python, JavaScript, curl, whatever your team uses.

Built by engineers, for engineers

If this saves each of my 8 CAD designers 30 minutes a project, that's 20 hours a week back. At our billing rate, that's $8,000 a month. I'd pay ten times what they're charging.

Frequently asked questions

No. CivDraw generates standard DXF files that open in any CAD software. AutoCAD, Civil 3D, BricsCAD, QCAD, LibreCAD. Most civil firms open the DXF in AutoCAD to add site-specific details before submission.

Every dimension is computed from governing standards (AASHTO, NJ RSIS, NJ DOT, ADA) with source citations. The drawings are a correct baseline that your PE reviews and stamps. We replace repetitive drafting, not engineering judgment.

Pro is $99/mo and includes unlimited drawings, AI assistance, and priority support. Contact us for team and enterprise plans.
