Draw accurately
Use lines, polylines, circles, arcs, offsets, trims and object snaps. Enter lengths and angles from the keyboard instead of estimating on screen.
Online technical drawing
Create an engineering drawing online, with dimensions
Build accurate 2D geometry in millimetres, organise it on drawing sheets and add dimensions without installing desktop CAD software.

A focused 2D CAD workspace for engineering documents
Chertilka combines drawing, annotation and sheet preparation in one browser workspace. It is suited to parts, assemblies, layouts and technical schemes where dimensions and a predictable paper scale matter.
Document the result
Add linear, radial and angular dimensions, leaders, text, tables, hatches, layers and title-block information.
Work with files
Import DWG and ASCII DXF without registration. Supported vector PDF geometry can be imported; a scanned page can be placed as a scale-calibrated background.
How it works
Set up the sheet
Choose paper size, orientation and scale. Model geometry remains in real millimetres while the sheet controls printed size.
Draw and check
Create geometry with snaps and exact values, then organise objects on layers and verify the key dimensions.
Prepare output
Add annotations and title information. Printing and PDF, DWG or DXF export become available with an active paid plan.
Free and paid access, without surprises
You can draw, import DWG/DXF and keep a project in this browser for free. Free sheets carry a watermark. Printing, file export and server storage require an active paid plan; pipeline tools and as-built documentation require the Extended plan.
Before issuing construction or manufacturing documentation, verify dimensions, standards and imported geometry against the source file.
FAQ
Can I draw without an account?
Yes. The editor opens in guest mode and supports drawing plus DWG/DXF import. The project is kept in the browser.
Is this a full 3D CAD system?
No. Chertilka is intentionally focused on technical 2D drawings and documentation, not solid modelling or engineering simulation.
Does zoom change the drawing scale?
No. Zoom only changes the screen view. Geometry stays in model millimetres and each sheet has its own paper scale.
