The Easy Choice for Creating Your CAD Drawings Online

Easy to Use

SmartDraw's CAD drawing software has the CAD tools you need to make scaled drawings of all kinds without CAD training and cost. Start with any of the built-in CAD templates and drag and drop symbols. You can set the size of walls or objects by simply typing into the dimensions label. You can also set the specific angle between two walls.

Easy to Find the Symbols You Need

SmartDraw includes a vast collection of mechanical engineering and architectural symbols for every type of CAD drafting project. You'll get industry-standard symbols for:

  • Doors
  • Windows
  • Lighting fixtures
  • Cabinets
  • Counter tops
  • Storage
  • Bathtubs and showers
  • Toilets
  • And more
Architectural symbols

Industry-Standard Callouts and References

You can easily add common architectural callouts, keynotes, markers, and references including:

  • Door numbers
  • Window numbers
  • Elevation marks
  • Drafting compass
  • Directional arrows
  • Revision numbers
  • Keynote numbers
  • Callouts
  • And more

Easy to Add Doors and Windows

SmartDraw has built-in automation that lets you attach doors and windows to your walls more easily than traditional CAD programs. Doors and windows will automatically snap and rotate with walls. When you see your cursor change to an anchor, you'll know your door or window will attach to the wall at that spot. Once attached, you can resize the opening and move it around on the wall until it's positioned where you want. The distance guides will help you position things accurately.

Place Items Precisely

As you drag a symbol to your floor plan, you'll see exactly where your object will be in relation to the walls and other objects in your plan. The blue guidelines will show the distance to the nearest wall or nearest object to help you position it.

Use guides to position items

Import an Existing Drawing

If you have an existing CAD file as an image or PDF, you can import it into SmartDraw, scale it, and draw your new designs or plan right on top.

Draw Custom CAD Symbols

Draw custom shapes from scratch or import images, then organize everything into shared custom libraries your entire team can use.

Enrich Your CAD Drawing with Data

Add model numbers, costs, descriptions, and other important manufacturing information to elements in your floor plan to display as a tool tip.

You can also export this data as a manifest. You can export the number of chairs of a certain model or get a list of equipment based on purchase date.

Enrich your floor plan with shape data

Easy to Draw and Print to Scale

SmartDraw lets you quickly select a common standard architectural scale, a metric scale, and more. You can print to scale just as easily. And your printed scale doesn't have to match your drawing's scale. You can easily change the scale at any time, even after you've started drawing. Keep track of your settings in a scale-independent annotation layer.

Manage Complexity with Layers

Layers let you separate your CAD design into distinct views and focus on the system you're working on. You can manage complex electrical, plumbing, HVAC information easily and make edits without affecting other parts of your plan. Use a scale-independent annotation layer to keep track of information like the CAD drawing's author and other settings.

Easy to Share

Share your CAD drawing with anyone, even if they don't own a copy of SmartDraw, with a link. You can also easily export any diagram as a PDF or common image formats like PNG or SVG.

How to Create Your CAD Drawing Online

Step 1

Pick a Template

Determine the type of diagram you're going to make. SmartDraw has templates for all kinds of floor plans to warehouses and offices.

SmartDraw also has templates for engineering diagrams including circuit diagrams, wiring diagrams, HVAC diagrams, piping diagrams, and more.

Step 2

Take Measurements for Scaled Drawings

If you're making a scaled CAD drawing like a blueprint or floor plan, you'll want to start by taking measurements of any existing structures. If you're creating a new plan, brainstorm designs based on the size and shape of the location on which to build.

Step 3

Draw Lines or Walls

Engineering diagrams like circuit diagrams will use lines and connect symbols that represent components like switches and fuses.

The foundation of most floor plans will be creating an outline of walls much like lines.

Step 4

Find Symbols and Add Them

Find the symbols needed to create your design. Most engineering diagrams like HVAC and electrical drawings will have specialized symbols that represent components you need. These will be docked to the template you selected.

You can also search for symbols and easily drag and drop symbols to your drawing area and connect them.

Step 5

Print or Share Your CAD Drawing

Once your drawing is finished you can insert it directly to Microsoft Word®, Excel®, PowerPoint®, Google Docs, Google Sheets, and more.

SmartDraw also has apps to integrate with Atlassian's Confluence and Jira. You can share your design in Microsoft Teams. You can also easily export your plan as a PDF, PNG, SVG, or print it.

CAD Templates and Examples

SmartDraw comes with dozens of templates to help you create blueprints, landscape layouts, electrical schematics, mechanical drawings, block diagrams, facility plans, circuit diagrams, and more.

Who uses CAD software?

CAD drawings are used by architects, civil engineers, mechanical engineers, and construction professionals.

Types of CAD drawings

CAD drawings can include floor plans, blueprints, piping and instrumentation diagrams, HVAC, site plans, wiring diagrams, circuit diagrams, and other technical drawings. Learn more.

Is CAD hard to learn?

Traditional CAD software like AutoCAD is well-known for having a steep learning curve. CAD doesn't have to be hard. SmartDraw was designed to be more accessible and easier to use.

Does SmartDraw import Visio files?

To help you move away from legacy software, SmartDraw can import and edit Visio® diagrams and stencils. See how good SmartDraw's Visio import is.

What is the best CAD software?

There are many options when it comes to choosing CAD software, and all options have their perks and drawbacks.
