Full instructions and FAQs
Start CAD with underlays, drawing types and layers
Complete and review the walls, openings and major furniture. CAD shares this architectural data.
- 01
Open CAD
Select the design and level, then CAD / services. Check orientation and units: CAD uses millimetres rather than the centimetres common in design fields.
- 02
Choose a drawing
Select combined M, dimensions A, lighting E1, power E2 or plumbing P. Separate drawings retain architecture, dimensions and annotations.
- 03
Set layers
Hide unnecessary layers or lock those you do not want to move. Edit architectural walls and openings in 2D / 3D.
- 04
Navigate and inspect
Pan, zoom or fit the drawing, then edit selected elements. Check the current drawing and visible layers before saving: exports and quantities use visible content.
Check your work
Switch drawing types and confirm the required points and lines remain available.
Can I import DWG or DXF?
DXF export is supported. DWG / DXF import and full AutoCAD editing are not currently available.
Does hiding a layer delete its elements?
No. Hidden and locked elements remain in the design.
Draw lighting, switches, sockets and circuits
Prepare confirmed point locations and circuits. This tutorial does not provide load or protection design.
- 01
Choose the drawing
Use E1 for lights and switches, and E2 for sockets, distribution boards, air-conditioning power and network points. Check furniture and door locations.
- 02
Place points
Select the appropriate symbol and place each point. The system assigns numbers, which you can adjust to the project convention.
- 03
Enter properties
Set the circuit, installation height and notes. Leave unconfirmed specifications unset rather than treating tutorial examples as construction instructions.
- 04
Connect the route
Place the start, bends and endpoint with the matching line tool. Press Enter or Finish. Edit nodes and check point references against circuits.
Check your work
Check every point, circuit and height, then inspect quantities for duplicates.
Does it calculate electrical loads?
No. It records layouts but does not calculate loads, design protection or approve construction.
How do I cancel an unfinished route?
Esc cancels the route. Backspace removes the last node.
Draw water, drainage, valves and outlets
Prepare confirmed water points, drain directions and specifications. These are layout drawings, not complete engineering calculations.
- 01
Open the plumbing drawing
Select P and check the kitchen, bathroom, balcony and equipment. Retain furniture as an underlay if helpful.
- 02
Place valves and outlets
Place valves or floor drains and verify their references. Use numeric or keyboard adjustments for precise locations.
- 03
Draw pipe routes
Draw cold water, hot water and drainage separately. Use orthogonal or free positioning as needed, then edit nodes after completing the route.
- 04
Add specifications
Enter pipe size, mounting height, drainage gradient and notes. Save and review quantities; lengths follow only the drawn routes.
Check your work
Check against the site and approved drawing, including water types, flow directions and labels.
Do quantities include risers and waste?
No. Risers, connections and wastage are not added automatically.
Does 3D create a complete services network?
No. The 3D services view illustrates the planar layout rather than a fully height-resolved network.
Add dimensions, leaders and precise nodes
Review the underlay scale first. Dimension annotations cannot correct an incorrectly scaled drawing.
- 01
Choose two endpoints
Select the dimension tool and both endpoints. The displayed straight-line distance is in mm; a diagonal distance is not a horizontal clear width.
- 02
Offset the dimension
Move the dimension outside the plan and separate multiple dimension chains. Keep labels clear of openings and other annotations.
- 03
Add a leader
Place the arrow and text position, then describe the target and requirement clearly. Avoid vague notes with no identifiable object.
- 04
Refine nodes
Enter millimetre coordinates or add bends. Arrow keys move 10 mm, or 1 mm with Shift. Recheck dimensions after editing.
Check your work
Cross-check a known site length and make sure text is readable in print preview.
Are DXF dimensions associative?
No. Dimensions export as visible lines and text, not associative DIMENSION entities.
How do I reduce clutter?
Offset dimension chains, remove overlapping annotations and choose a suitable paper size and scale.
Export DXF, PDF drawings and services quantities
Save and check the layers first. Use the correct paper and 100% printing scale.
- 01
Choose the scope
Select the drawing and visible layers, including furniture if needed. Exports and quantities follow visible content, so check for missing points.
- 02
Fill the title block
Choose A3 or A4 landscape, a scale, drawing number, revision, author and reviewer. Adjust paper or scale if the plan is too large.
- 03
Preview and print
Download SVG or print to PDF. Select 100%, turn off headers and footers, and avoid fit-to-page. Correct overflow before printing.
- 04
Download DXF and CSV
DXF exports lines, circles and text at 1:1 in millimetres. CSV counts visible points and drawn route lengths for a separate material review.
Check your work
Reopen the output and check a known length, drawing number and point count. Measure the printed scale too.
Does the quantity list create a purchase order?
No. Review connections, risers and waste before creating material requirements.
Does DXF include full furniture models?
No. Furniture exports as simplified plan outlines rather than full 3D models.
