The top questions that
we get asked

At its core, CAD design involves the use of software to create precise drawings and technical illustrations. These designs can be two-dimensional (2D) or three-dimensional (3D), enabling detailed visualization and manipulation of an object or a system before it is physically produced. The use of CAD software facilitates accuracy, efficiency, and flexibility in the design process, reducing the likelihood of errors and allowing for easy modifications.

2D CAD Design
2D CAD involves the creation of flat, two-dimensional drawings that represent objects using width and height. These designs are akin to traditional paper drawings but are created and modified using computer software. Here are some key characteristics and applications of 2D CAD.

3D CAD Design
3D CAD, on the other hand, involves creating three-dimensional models that represent the actual depth, width, and height of an object. These models can be rotated and viewed from any angle, providing a comprehensive understanding of the design.

We are a versatile engineering firm renowned for delivering a wide range of high-quality services to meet diverse industry needs. Our expertise spans across multiple engineering disciplines, offering innovative solutions that cater to both commercial and industrial sectors.

The main file formats for CAD design files varies depending on the software being used, but there are a couple that are widely recognised and employed across different CAD applications.

DWG (Drawing)

Used By: AutoCAD and other Autodesk products.

Description: DWG is one of the most popular CAD file formats and contains both 2D and 3D design data. It is a proprietary format developed by Autodesk.

DXF (Drawing Exchange Format)

Used By: Various CAD software.

Description: DXF is an open-source format created by Autodesk to facilitate data interoperability between AutoCAD and other programs. It supports 2D and 3D designs and is widely used for sharing CAD files.

This depends on the project scope and services used. However, we typically charge £37.50/hr for our CAD Design and Draughting work. Fabrication and installation is project dependent.

Twenty20 Engineering works predominately in the Construction and Offshore Sectors. We have worked with multi-billion-pound companies such as BAM Construction and Morgan Advanced Materials, as well as small and medium-sized enterprises. We have worked with Structural steel fabricators Advertising and Media Hydrographic Surveyors Agricultural Equipment Suppliers Industrial Plant Suppliers

we are based in Birkenhead, Merseyside and predominately work in the NW. However, we operate UK-wide and have completed projects overseas in France, Switzerland, Iceland, and the USA.

We use AutoCAD, SolidWorks, and Tekla Structures. So, all types of projects can be covered.

Quick Turnaround, depending on project size we aim to complete the GA for approval within 10 working days, and fabrication packs within 1 week of approval Cost-effective, we can offer competitive fixed prices for projects, or longer-term projects a fair hourly rate Efficient, we use CAD all the time and have designed loads of things, so we know how to deliver a project quickly Accuracy, we have a 2-stage checking process for all drawings issued to ensure there will be no problems during fabrication Experience, we have completed projects that have ended up all over the UK, as well as France, Switzerland, Iceland and the USA. 

We have a simple 3–step process for all design work:

• Step 1 - design consultation to understand the project scope and specification
• Step 2 - issuing a general assembly drawing and model for approval
• Step 3 - Issuing a finalized Fabrication Pack and Schedules for manufacture and install
