Quality drafting services are essential for the construction of your dream home. These technical drawings ensure that all the builders and tradespeople involved in the construction process know precisely what to do ⸺ much like a formula to your project’s success. Here, we will discuss the two types of drafting services you will encounter in your journey: CAD drafting and manual drafting.
Manual drafting is all about producing all these technical drawings by hand using drafting pencil, or drafting pen, drafting paper, a scale ruler and stencils.
CAD drafting, on the other hand, uses software that simplifies and speeds up the production of technical drawings because it features drafting sheet templates and automatically duplicates repeating design elements. CAD drawn documents can be updated simply and quickly if a revisions or change needs to be made.
Nowadays, only a handful of architects, building designers, and draftspeople still hand draft technical drawings. They now prefer using CAD softwares because these are more preferred by builders and the authorities.
How designers use manual drafting
Still, there are many homeowners who admire hand drafted drawings. They appreciate it because it reflects the creativity of the design professional they hired for their project.
Also, manual drafting shows how skilled the architect, building designer, or draftsman is. It gives them an opportunity to showcase what they can do. This is the case for design professionals who like to go ‘old school’ from time to time. Manual drafting allows them to continue practising the skills they’ve developed in the early stages of their careers. They do this to avoid getting rusty or too reliant on computers.
Even if they can’t do or submit hand-drafted planning documents all the time, they still use their beautiful artistic hand every time they start a new project. Design professionals usually provide concept drawings to their customers at the end of a consultation. They sketch out a design while the customer briefs them as a way of capturing their thoughts and vision. These sketches are usually discarded after the first stages of a project, but feel free to keep them as a remembrance.
Advantages of CAD drafting over manual drawings
As mentioned earlier, a majority of architects, building designers, and draftspeople prefer using CAD software mainly because it speeds up this tedious process.
Because today’s customers require stricter deadlines and faster turnaround time for their projects. The design professionals must keep up with the demand and must complete the drawings in a shorter period of time.
Here’s how CAD software speeds up the production of technical drawings:
Using CAD software makes their work more accurate
Manual drawings, being done by hand, often have a lot of human errors that need to be corrected. Redrawing takes a lot of time. In worse cases, they need to start from scratch. When this happens, it would be hard to deliver the drawings on time.
CAD software helps the draftsman produce more accurate scale drawings. It features a toolset that calculates the sizes, alignments, and dimensions; then does more basic tasks automatically.
When the drawings are accurate, tendering and construction would be a breeze.
It’s easier to revise planning documents using CAD software
CAD enables the draftsman to make quick revisions and fix errors in each draft. The final planning documents would be neat, with no trace of revisions at all.
In manual drawings, the drafter would erase and redraw the parts that need to be fixed, which degrades the clarity of the paper and the whole document. If the modifications are so large, the draftsman has no choice but to retrace and redo the drafting.
CAD creates ready-made templates and databases
The draftsman saves a lot of time using CAD because the software lets them use templates like these in all their drawings. All these drawings are saved in a database and can be reused for future projects. This significantly speeds up the drafting workflow.
Teams of draftsmen work more efficiently with CAD
In manual drafting, a team of draftsmen often work simultaneously to meet the deadline. This is hard because people are supposed to work like one, but people are not always in tune with each other. Consistency and accuracy will be an issue.
This is not the case with CAD. Collaboration is better because everything is digital. Workflow is smoother and the final planning documents will come out consistent.
CAD drawings are compatible with 3D modelling software
Unlike manual drawings, CAD drawings are used to develop CGI visuals, 3D models, and BIM models for developing constructions.
Here at Superdraft, we often convert 2D CAD drawings into 3D models, then produce immersive 3D virtual home tours with it.
Another advantage of creating a 3D model is if a design element changes within the model, it will be reflected in the floor plans and elevations globally – without the need to go back and update all of these other drawings one by one.
All these reasons make CAD drawings an efficient choice for the first phases of the project. It streamlines the tedious process of producing technical drawings and removes human error.
Here at Superdraft, we offer more than digital drafting services to our customers. As the entire process needs to be efficient, we also give our customers access to our online project planning platform where you can review and mark up the drawings from your draftsman.
