Free ship general arrangement blocks for AutoCAD (DWG): cargo ships, tankers, deck equipment, engine room, cabins, tanks

About the symbols

General arrangement drawings follow the practice of the yard, the classification society and the flag state; there is no single drawing standard for them. The fire and life-saving marks in this library are simplified common forms and are not the symbol sets of the IMO resolutions: use the sets that your flag state and class require for fire control and safety plans.

The blocks are our own drawings, not copies of any manufacturer's catalogue, and the library is not certified. Sizes are typical for each equipment class, not manufacturer data. Take exact outlines, service space and ratings from the supplier's drawings.

Frequently asked questions

Which items are in the library?

Ship types in profile and plan, deck equipment, masts, funnels and navigation, life-saving appliances, cargo spaces and handling, machinery and propulsion, accommodation and bridge, tanks and compartments, fire and safety, and drawing marks. The page above lists every group with its count.

Can I use the fire and safety blocks for a fire control plan?

They are simplified forms for arrangement drawings, not the symbol sets of the IMO resolutions. For a fire control plan or a safety plan use the symbols that your flag state and classification society require, and use these blocks for the layout under them.

Can I use the symbols in commercial projects?

Yes. They are free to use and modify in your own projects, including commercial ones. They are provided as is, without warranty.

Are the ship outlines exact?

No. They are typical outlines of each ship class, good for general arrangement sketches and for placing equipment and compartments. For a real ship use its own lines plan and general arrangement.

Can I change a symbol or add attributes?

Yes. Open the DWG, edit a block with BEDIT to change it or add attributes, and save. To update drawings that already contain the block, run ATTSYNC or replace the block. Make a backup first: attribute values can be lost if ATTSYNC is used carelessly.

Where do I find a ready-made set of these symbols for AutoCAD?

AutoCAD itself ships only a small set of sample blocks, so a full symbol set has to come from a library. Download the ZIP on this page and open the DWG: every symbol is a block. Insert one with INSERT (Blocks palette, Libraries tab, then pick the DWG) or drag it from DesignCenter (ADCENTER). You can also download a single symbol on its own.
