Getting Started with FlexiCAD: A Beginner’s TutorialFlexiCAD is a modern, adaptable CAD application designed for designers, engineers, architects, and hobbyists who need a flexible, efficient tool for 2D drafting and basic 3D modeling. This beginner’s tutorial walks you through installation, the interface, basic workflows, core tools, common tasks, and tips to speed up your learning curve so you can go from zero to productive quickly.
Why choose FlexiCAD?
- Lightweight and fast — runs well on modest hardware.
- Intuitive interface — low learning barrier for users migrating from other CAD packages.
- Customizable workspace — toolbars, palettes, and shortcuts can be tailored to your workflow.
- Good format support — imports/exports common formats (DWG, DXF, SVG, STEP) for collaboration.
- Extensible — supports plugins and scripting for automation.
1. Installing FlexiCAD
- Download the installer from the official FlexiCAD website or your organization’s software portal.
- Run the installer and follow prompts: choose typical or custom install, select installation folder, and accept the license.
- On first launch, choose your workspace preset (e.g., Drafting, 3D Modeling, or Lightweight). Presets configure toolbars, grid settings, and units.
System tips:
- Recommended minimum: 8 GB RAM, dual-core CPU, and a GPU with OpenGL support for smoother panning/zooming.
- Use a mouse with a middle-wheel for quick pan/zoom navigation.
2. The Interface — what to know
FlexiCAD’s interface centers on an editable drawing area with dockable panels around it.
Main components:
- Menu bar — file, edit, view, tools, plugins, help.
- Toolbar/ribbon — grouped drawing and modification tools.
- Properties panel — shows properties for selected objects (layer, color, line type, dimensions).
- Layers manager — organize content into named layers with visibility and lock controls.
- Command line / Input bar — type numeric values or commands directly (handy for precision).
- Status bar — coordinate readout, snap toggles, grid and ortho mode.
Shortcuts to remember:
- Middle mouse drag — pan
- Scroll wheel — zoom
- Ctrl+Z — undo
- Space or Enter — repeat last command (configurable)
3. Document setup: units, grid, and layers
Before you draw, set up your document:
- Units: File > Document Settings > Units. Choose metric (mm, cm, m) or imperial (inches, feet).
- Grid & snap: Toggle grid from the status bar. Configure snap increments to align objects precisely.
- Layers: Create layers for different elements (e.g., Walls, Dimensions, Annotations). Assign colors and line types for clarity.
Why layers matter: they let you hide or lock parts of the drawing while editing others, and help with exporting specific elements.
4. Basic drawing tools
Common tools you’ll use immediately:
- Line: click start, click end, or type length and angle for precision.
- Polyline: draw connected line segments and arcs as a single object.
- Circle: center-radius or 3-point methods.
- Rectangle: corner-to-corner or center + dimensions.
- Arc: start, end, radius or tangent-based construction.
- Text: single-line and multi-line annotation with font and size controls.
- Dimension: linear, aligned, radial, angular — place dimensions that update with geometry.
Practical tips:
- Use ortho mode (constrains to horizontal/vertical) for orthogonal drafting.
- Use temporary tracking lines (if available) to place objects relative to existing geometry.
5. Modify tools and precision editing
After drawing, use modify tools to edit geometry:
- Move, Copy, Rotate, Scale — standard transforms.
- Trim, Extend, Fillet, Chamfer — refine intersections and corners.
- Offset — create parallel curves or lines at a set distance.
- Mirror — produce mirrored geometry across an axis.
- Boolean operations (in 3D mode) — union, subtract, intersect for solids.
Precision techniques:
- Use object snaps (endpoint, midpoint, center, intersection, tangent) to ensure accurate placement.
- Use coordinate entry for exact positions: type X,Y or use relative entry like @100,0.
6. Working with blocks and reusable content
Blocks (or symbols) let you reuse standard details:
- Create a block: select objects > Block > Create. Give it a name and insertion point.
- Insert block: pick from the block library and place with scale/rotation options.
- Edit block: use Block Editor to change the block; instances update automatically.
Use cases: title blocks, fixtures, standard components, repeated annotations.
7. Simple 3D modeling basics
FlexiCAD’s 3D tools are designed for basic modeling and visualization:
- Primitive creation: box, cylinder, sphere, wedge.
- Extrude: convert a 2D profile into a 3D solid.
- Revolve: rotate a profile around an axis to form symmetric parts.
- Loft and sweep (if included) for more complex transitions.
- View controls: orbit, zoom, pan, preset views (Top, Front, Right, Isometric).
- Simple materials and lighting for quick render previews.
Export tip: export solids to STEP for mechanical CAD interchange.
8. Annotation and printing
Make your drawings readable and presentable:
- Add title blocks, revision tables, and layer-based printable styles.
- Use scale views: create viewports in layouts/paper space and set annotation scaling so dimensions read correctly at print scale.
- Plot/Print: File > Print/Plot. Choose paper size, orientation, and scale. Preview before finalizing.
Common cause of bad prints: forgetting to set the correct drawing scale in the layout viewport.
9. Saving, exporting, and collaboration
- Save formats: native FlexiCAD (.flexi), and export to DWG/DXF for compatibility.
- Export to PDF for sharing with non-CAD users.
- Use Xrefs (external references) to link large assemblies or separate discipline files—update-linked files automatically when source changes.
- Version control: keep iterative filenames or use the built-in revision manager if available.
10. Automation, plugins & scripting
FlexiCAD supports plugins and scripting (usually via Python or a proprietary macro language) to automate repetitive tasks:
- Automate batch exports, layer cleanup, or create custom commands.
- Install plugins from the marketplace to add CAM export, advanced rendering, or parametric tools.
Example: a small script can rename layers by prefix, export each layer to a separate DXF, and compress them into a ZIP for handoff.
11. Troubleshooting common beginner issues
- Objects not visible: check layer visibility and object color (white on white).
- Snap not working: ensure snaps are enabled and correct snap types selected.
- Dimensions not updating: ensure associative dimensions are on; consider re-associating or recreating if geometry changed.
- Slow performance: reduce visual styles, turn off real-time shadows, or freeze unused layers.
12. Learning resources & next steps
- Official FlexiCAD documentation and tutorial videos (start with the basics then follow workflows).
- Community forums and user groups for templates, plugins, and tips.
- Small projects to practice: draw a floor plan, model a simple mechanical bracket, or recreate a furniture piece.
- Invest time in learning layer management, object snaps, and block libraries — these skills multiply productivity.
Quick starter project (30–60 minutes)
- Create a new metric document. Set units to mm.
- Draw a 4000 x 3000 mm rectangle (outer walls). Offset 200 mm inside for wall thickness.
- Add two interior partition lines and a doorway opening (use trim).
- Insert windows as blocks and add annotations and dimensions.
- Save as .flexi and export a PDF for printing.
FlexiCAD is approachable for beginners but powerful enough to scale into professional workflows with customization and scripting. Start small, practice the core tools, and gradually add plugins and automation as you need them.
