Choosing drafting software for residential plans

Most small builders choose drafting software the way they choose a phone: by the feature list, the price and what a friend recommends. That approach works for a tool used occasionally. A drafting package used every day on working drawings is a different matter, because it sets how quickly plans are produced, how easily they are shared with consultants and whether the drawings look right when they reach the certifier. A poor choice is paid for in redraws, late approvals and a team that quietly stops using the tool.

This article judges drafting tools on three things that matter to a builder producing their own working drawings for residential jobs: the files they open and send, the output standards they can hold, and the skills the people in the business already have or can realistically build. It is about two-dimensional plans, elevations, sections and details, not model-based workflows. Our article on BIM for residential builders covers the model-based side, which is a different task with different costs.

The commercial stake is the redraw. A set of drawings that a certifier cannot read, or that an engineer must reproduce in their own software, costs time at the worst point in the job. The builder pays for the extra drafting, the delay in approval, and the phone calls that follow. A tool chosen for the wrong reasons can cost more in those hours over a year than the licence fee ever did.

Start with what the drawings have to do

Before comparing software, be clear about what the drawings are for. A working drawing set for a residential job usually includes a site plan, floor plans, elevations, sections and the details that show how the building is put together. Each sheet has to be read by someone else: a certifier checking compliance, an engineer checking structure, a council officer assessing an application, a subcontractor setting out a wall and a client trying to understand the house. The tool has to produce drawings that serve all of those readers, not only the person who drew them.

That is why the list of features should come second. A tool that can produce photorealistic renders is not automatically better for a set of working drawings, and a tool that can produce a clean sheet with a correct scale bar and a legible dimension is doing the job that matters. Ask what the typical sheet needs, then test whether the software produces it quickly and consistently.

Be realistic about the volume of work too. A builder who draws a handful of jobs a year has different needs from one who turns out plans for a team every month. A low-volume user may be better served by a simple tool used well than by an advanced one that is opened only now and then and relearned each time. Match the tool to the workload that is actually there.

File compatibility: the test that decides everything

The most important question is whether the tool opens the files your consultants send and produces files that the people downstream can open. Surveyors, structural engineers, energy assessors and certifiers each have their own software and their own preferred formats. Some work in a drawing exchange format, some expect a PDF, and some will only accept a native file from a specific package. A drafting tool that cannot read the surveyor’s base plan is a tool that will be replaced after the first job, at a cost.

Check the export as well as the import. A drawing that looks correct on screen can lose its layers, its scale or its line weights when it is exported to a PDF or a drawing exchange file. Export a test sheet, open it in a different program and print it at the intended size. If the scale bar no longer matches the dimensions, or the text has moved, the tool is not ready for working drawings, however good the interface looks.

Pay attention to fonts and symbols. A title block that depends on a font the recipient does not have will change its appearance when it is opened, and a symbol library that exists only on one machine will leave the drawing unreadable elsewhere. Use common fonts, keep the symbols embedded or shared, and make sure the house template travels with the files rather than living on a single laptop.

Our article on digital measuring tools that log results covers a related question: the data a site measurement produces has to reach the drawing without retyping, and the same test of compatibility applies to it.

Output standards: making every sheet read the same way

Working drawings are judged on their presentation as much as their content. Each sheet needs a title block with the job, the sheet number, the revision, the scale and the author; a north point where the plan orientation matters; scale bars that stay correct when the sheet is printed at a different size; and lettering that can be read at the size it is printed. Line weights should distinguish the cut lines from the background and the dimension lines from the notes, because a reader who has to guess which line is which will misread the drawing.

The tool must hold those standards from a saved template. A builder who rebuilds the title block and the text styles on every sheet will make mistakes, and the mistakes will be different on each one. Set the template up once, test it on a real sheet, and make sure every new drawing starts from it. Check that revisions update the title block and the sheet list automatically, because a revision that is missing from one sheet is a drawing that will be built from the wrong information.

Dimensioning is where the standards are tested hardest. Dimensions must be placed where the reader will look for them, they must agree with the drawn geometry and they must be updated when the design changes. A tool that allows dimensions to drift from the geometry, or that makes the dimension style hard to hold consistently across sheets, is a source of errors that a certifier will find and a subcontractor may not. Check the dimension tools on the trial sheet, not on the demonstration.

Keep the sheet list and the revision history inside the drawing set, not in a separate spreadsheet that drifts away from the drawings. A certifier who receives a revised sheet with no matching entry in the list will ask which version is current, and the answer should be on the page. Assign one person to issue each revision, and record who approved it and when, so the set always tells its own story.

In-house skill: the cost that decides the outcome

A drafting tool is only as good as the person using it. The most capable package in the market will produce poor drawings in the hands of someone who cannot yet set the scale, and a simple tool will produce good ones in the hands of someone who has used it every day for a long time. Be honest about who will do the drawing, how much time they have and how much they already know. A builder who draws in the evenings should choose for an evening learning curve, not for a full-time drafter’s workflow.

Plan for the learning curve as part of the cost. Training time is paid for, even when it is done on the job, and the first sheet produced by someone new to a tool takes much longer than a later one. A tool that the team can use competently within a short period is worth more than one that is ultimately more capable but takes months to master. Ask the vendor what support and training exist, and whether it is available in plain English on the day you need it.

Think about succession as well. A drafting setup that lives in one person’s head and one person’s laptop will be lost when that person leaves. Keep the template, the symbol library and the instructions in a shared location, and make sure at least one other person can open and print a sheet. Our article on business systems for a small builder covers the same principle for the rest of the office.

Cost, licensing and where the files live

The licence fee is the number most people compare, but it is rarely the largest cost. Consider the cost of the hours spent learning the tool, the cost of redraws when files do not transfer, and the cost of a licence that lapses in the middle of a job. Check how the licence works for a team: whether each user needs their own seat, whether the seat can move between machines, and what happens to the files if the subscription is not renewed.

Storage matters more than most builders expect. Working files should sit in a known location with a backup, and the drawings should not exist in one place only. Cloud storage can be a sound option, provided access is controlled, the account is protected with strong sign-in arrangements and someone is responsible for it. The Australian Signals Directorate publishes practical guidance for small businesses on protecting their systems, and it is worth applying to the drawing files as much as to the accounts.

Client plans contain personal information: names, addresses, contact details and sometimes financial or family circumstances. The Office of the Australian Information Commissioner provides guidance for small businesses on privacy, and whether the Privacy Act applies depends on the business. Even where it does not, the sensible approach is to keep client files controlled, to share only what a consultant or a certifier needs and to delete the copies that are no longer required.

Trialling a tool before you commit

The only reliable test of a drafting tool is a trial on a real job. Demonstrations are designed to show the tool at its best, and a sales call is not a drawing. Set up a trial with a job that already has its plans drawn, so the output can be checked against a known sheet, and run the test with the person who will use the tool every day. The trial should answer three questions: can the team produce the sheet, does the sheet come out right and does it survive the trip to the consultant and back.

Keep the decision honest. A trial that goes well but takes twice as long as the current method is not a success unless the saving in the long run is clear. Write down the time taken, the problems found and the cost, and make the decision against those numbers rather than against the impression the demonstration left. If the tool does not pass the trial, it does not matter how good it looks on the vendor’s website.

A worked example: a builder moving from hand sketches

A builder in regional NSW had been producing his own plans by hand for many years, with a sketch set that the local draftsperson would tidy up for the council. The business was growing, the draftsperson was busy elsewhere, and the builder decided to bring the drawing in-house with software. He chose a package that his supplier recommended, because it had a strong three-dimensional view that he liked to show clients.

The first trial went badly. The tool was clear enough for the builder to draw a simple floor plan, but he could not produce a title block that held the same format on every sheet, and the dimensions drifted when he changed the design. The engineer’s base plan also came in a format the tool would not open cleanly, so the builder had to retrace it by hand. Several evenings of work had produced one sheet he was not confident in.

The builder changed the approach. He moved to a simpler tool that imported the surveyor’s file cleanly, he built a house template with the title block and text styles, and he set up the dimension style once. He drew one complete sheet end to end, sent it to the engineer and the certifier in the formats they used, and checked that it printed correctly. The three-dimensional view stayed in the presentation folder, where it belonged, and the working drawings went out on time. The lesson was that the test of the tool was the file that left the office, not the view that impressed the client.

Keeping the choice under review

A drafting tool is not a decision made once. Software changes, the consultants change and the business changes, and the setup that was right when it was chosen may be wrong a few years later. Review the choice when the licence is renewed, when a consultant asks for a different format and when the team changes. A short review is cheaper than a redraw.

Ask the people who read your drawings what they find hard to use, and ask the people who draw them the same question. A certifier who has rung twice about the same dimension, or a subcontractor who keeps asking which sheet is current, is telling you where the set is failing, and that feedback is free.

The PointCPD course catalogue lists the NSW builder CPD courses available, and the working drawings that a builder produces are part of the evidence a licensed builder relies on every day. Keep the drawings controlled, the template consistent and the files where the team can reach them, and the software will do its job without becoming the job.
