Layer controls let you show or hide drawing components as a plan takes shape. QCAD is a 2D drafting program for technical drawings, including building layouts, interior plans, and machine-part outlines.
Building a drawing with layers
Create a drawing from basic entities such as lines, arcs, ellipses, text, and filled shapes. Layers organize those entities by purpose, so a floor plan might keep walls, doors, labels, and dimensions in separate groups. Hiding a layer clears the view temporarily while leaving its contents in the drawing.
Construction tools support placing and aligning geometry; modification tools handle changes to existing elements. This division suits a drafting workflow where a layout is assembled from precise shapes and adjusted as the plan develops.
What can you draw in QCAD?
QCAD is aimed at 2D technical work. Architectural users can draft building and interior layouts, while mechanical drafting can cover outlines and diagrams of machine parts. The same drawing approach also applies to other plans and technical diagrams.
- Use line, curve, ellipse, and shape tools to create geometry.
- Add text and fills to clarify drawing areas and annotations.
- Browse the included object library for reusable drawing elements.
Editing and organizing plans
A practical workflow is to build the main geometry, separate related elements onto layers, then use modification tools to refine placement or shape. Layer visibility makes it easier to focus on one part of a busy drawing while keeping other components available. Text and fills add labels and visual distinctions to the finished plan.
Pros
- Layer visibility separates drawing components without deleting them
- Construction and modification tools support iterative drafting
- A built-in object library supplies reusable drawing elements
- Drawing tools cover lines, curves, text, shapes, and fills
Cons
- QCAD focuses on 2D drawings; 3D modeling is outside its scope

What kinds of drawings can QCAD create?
It creates 2D technical drawings such as building layouts, interior plans, and machine-part outlines.
How do layers work in QCAD?
Layers group drawing elements and can be shown or hidden to control what appears in the view.
Can QCAD create 3D models?
No. QCAD is for 2D drafting.
