Before you can design anything, you need to find your way around the software. Watkins’ design team draw on a computer instead of a drawing board — and once you understand a few building blocks, almost every CAD package works the same way.
01 · Where you drawThe workspace
You draw in a big blank area at real-world size — a 3-metre wall is drawn 3 metres long. You zoom and pan around it like a map, and only shrink it to fit the paper right at the end. Getting used to working full-size, then scaling to print, is the first mental shift.
02 · Precision, not eyeballingDrawing accurately
CAD isn’t freehand. You type exact lengths and coordinates, and snapping makes your cursor lock onto precise points — the end of a line, the centre of a circle. A drawing that only looks right is worse than useless on site.
03 · Keeping it organisedLayers
Everything sits on a named layer — walls on one, pipework on another, electrics on another, text on another. Layers let you show, hide and colour-code parts of the drawing so a busy sheet stays readable.
04 · Lines that mean thingsLine types
A solid line, a dashed line and a centre line all mean different things. Using them consistently is how anyone can pick up the drawing and read it the same way you did.
05 · Draw once, reuseBlocks & symbols
You don’t redraw a radiator or a socket every time. Common items are saved as blocks (symbols) and dropped in wherever needed — faster, and consistent across every drawing.
06 · Getting it outPlotting & issuing
Finally the drawing is set to a scale, given its title block, and plotted or saved to PDF so it can be issued. That’s the moment your work leaves the screen and heads to site.
The software is just a tool. The buttons and menus change between packages, but the thinking — accuracy, organisation, and drawing so other people understand — stays exactly the same. Learn the principles and you can pick up any CAD program.
So…What’s next
Your buddy will sit you in front of the real software and walk you through these one by one. You’ll be drawing something simple within the hour — and it’ll make a lot more sense now you know what you’re looking at.
