- CADCraft bracket design uses a command-driven 2D drafting workflow that runs directly in the browser.
- Start with centerlines and base geometry, then refine with Trim, Offset, and Fillet-style edits.
- Organize the bracket on separate layers for outline, holes, dimensions, and centerlines.
- Create reusable blocks for mounting holes so repeated features stay consistent.
- Export the finished bracket as DWG or DXF for exchange, or PDF for review copies.
Bracket Design Basics in CADCraft
A bracket is one of the most practical first projects in any CAD workflow: a flat mounting plate with holes, notches, and bends that requires only basic 2D geometry. CADCraft bracket design fits this task well because the application is built around a command-line-driven drafting experience that runs in the browser, so you can open the CADCraft web app and start drawing without installing anything.
Brackets are drawn with a small set of core commands: Line (L), Circle (C), Offset (O), Trim (TR), Extend (EX), Move (M), and Copy (CO). If you come from AutoCAD, these aliases will feel immediately familiar, although CADCraft is an independent product with its own development direction.
L-Bracket (Angle)
- Two flat legs at 90 degrees
- Mounting holes on each face
- Most common starter bracket
- Drafted with L, O, and C commands
Flat Plate Bracket
- Single-plane mounting plate
- Slots or holes for fasteners
- Easiest to dimension and export
- Good first block library candidate
U-Bracket (Channel)
- Base plus two side walls
- Requires symmetric offset work
- Practices mirror-like Copy workflows
- Intermediate difficulty
Sketch the bracket on paper first: leg lengths, plate thickness, hole diameter, and hole edge distances. Deciding these values before drawing prevents rework when dimensioning later in the session.
Step-by-Step: Drafting an L-Bracket
This workflow walks through a simple L-bracket: a 100 x 60 mm profile with 6 mm material thickness and two 8 mm mounting holes. The same sequence applies to any bracket size in CADCraft.
Set Up the Drawing
Open CADCraft in the browser and start a new drawing session. Create layers for the bracket outline, holes, centerlines, and dimensions before drawing any geometry, so every element lands on the right layer from the start.
Draw the Outer Profile
Use the Line command (L) to draw the outer L-shape. Pick the first corner point in the canvas, then enter the remaining points to form the two legs. Use relative distances typed at the command line for accuracy instead of eyeballing the canvas.
Offset the Material Thickness
Use Offset (O) with a 6 mm distance to create the inner profile parallel to the outer legs. Trim (TR) the excess segments at the corners so the outline reads as a clean closed L-profile.
Add the Mounting Holes
Draw a centerline on each leg, then use Circle (C) with a 4 mm radius (8 mm diameter) centered where the centerlines cross. Assign both circles to the holes layer, and keep the centerlines visible for dimensioning.
Dimension and Annotate
Switch to the dimension layer and add linear dimensions for leg lengths, thickness, and hole positions. Keep the dimension style consistent: place hole-to-edge dimensions from the same reference edge on both legs.
Review and Export
Zoom out and inspect the bracket at full scale. Confirm layer assignments and dimensions, then save the drawing or export a copy as DWG or DXF for downstream use, or PDF for a readable review copy.
Unclosed profiles and stray line fragments from offsets are the most common cause of confusing bracket drawings. After each Trim or Extend operation, zoom into the corners and confirm that only the intended segments remain.
Layers, Blocks, and Organization
Clean organization is what separates a bracket drawing you can reuse from one you have to redraw. CADCraft supports layer-based separation, linetype and lineweight control, and reusable blocks — all of which matter for bracket work.
| Layer Name | Typical Content | Lineweight | Notes |
|---|---|---|---|
| OUTLINE | Bracket outer and inner profiles | Heavy | Defines the part boundary |
| HOLES | Circles for mounting holes | Medium | Separate from outline for clarity |
| CENTER | Hole and symmetry centerlines | Light | Use a dash-type linetype |
| DIMS | All dimensions and annotations | Light | Keep off when exporting geometry only |
Once one mounting hole with its centerlines is drawn, define it as a block. Placing the block with Copy (CO) keeps repeated holes identical and makes edits propagate visually through consistent reuse.
A practical layer workflow also pays off when you migrate existing drawings: after opening a DWG or DXF from another tool, check that layers, linetypes, lineweights, and blocks survived the import before you start editing geometry.
Common Commands for Bracket Work
The commands below cover nearly everything a 2D bracket requires. Each can be entered through the command line or its alias.
| Command | Alias | Category | Bracket Use Case |
|---|---|---|---|
| Line | L | Drawing | Outer profile and edges |
| Circle | C | Drawing | Mounting and clearance holes |
| Offset | O | Modify | Material thickness and parallel edges |
| Trim | TR | Modify | Cleaning corners after offsets |
| Extend | EX | Modify | Closing gaps in the profile |
| Move | M | Modify | Repositioning holes or views |
| Copy | CO | Modify | Duplicating holes and repeated features |
| Layer | tools | Layers | Organizing outline, holes, centerlines |
| Dimension | tools | Annotation | Hole positions and leg lengths |
Pressing Enter at an empty command prompt repeats the previous command. This is especially useful during repetitive bracket work such as placing a series of holes with Copy.
Export, Review, and Quality Checklist
Before exporting, run a quick quality pass. Brackets are functional parts, so dimensional accuracy and readability matter more than visual polish.
Bracket Drawing Checklist:
- Outer and inner profiles form closed loops with no stray segments
- All holes placed on the holes layer with visible centerlines
- Every hole position dimensioned from a stated reference edge
- Material thickness clearly dimensioned on both legs
- Layers, linetypes, and lineweights assigned consistently
- Drawing saved and a copy exported as DWG, DXF, or PDF
Export format choice depends on the next step in your workflow:
| Format | Best For | Notes |
|---|---|---|
| DWG | Standard CAD exchange | Preferred when the recipient works in a CAD-native workflow |
| DXF | Cross-application data exchange | Use when interoperability is the priority |
| Review and printing | Fixed-layout readable copy, not editable geometry | |
| SVG | Vector graphics use | For design tools that need scalable vector output |
In the browser-based CADCraft file workflow, export a copy for sharing rather than treating the original upload as the deliverable. This keeps your editable source drawing intact for future revisions.
FAQ
Q: Can I design brackets in CADCraft without installing desktop software?
Yes. CADCraft currently runs as a browser-based experience, so you can open the drawing workspace and draft a complete 2D bracket, including layers and dimensions, without a desktop installation.
Q: Does CADCraft bracket design work with DWG and DXF files?
CADCraft supports a file-oriented workflow for opening, editing, and exporting drawings, with DWG and DXF as the key CAD exchange formats, plus PDF and SVG for document and vector output.
Q: Is CADCraft the same as AutoCAD?
No. CADCraft is an independent open-source-oriented application. Its command line, aliases, layers, and layouts feel familiar to AutoCAD users, but it is a separate product and should be learned as its own tool.
Q: How do I keep repeated mounting holes consistent?
Draw one hole with its centerlines, save it as a reusable block, and place additional holes with the Copy command. This keeps diameters and centerline styles identical across the bracket.
