SimpleCAD is an easy, simple to learn 2D Computer Aided Design program (CAD) made to meet all of your basic design needs.
SimpleCAD is more than just a vector paint program, because you could move, copy, edit, scale, rotate and offset… objects.

Main Functions of the application:

- Basic draw items: including freehand lines, line, polyline, orthogonal line, tangent line, parallel line, rectangle, polygon, circle, arc (NOTE: native ellipse is not supported, only support ellipse created by polyline object). Text box, callout box, picture box (imported from image file), measure items…

- Modify functions: move, erase, copy, mirror, offset, rotate, scale, stretch items' vertices, lengthen, trim, extend, break, chamfer, fillet and explode polyline, join, array, polar array.

- Auto Snap point setting: Snap to grid, end points of objects, on entity, center of arc - line - circle, middle point of arc - line, intersections, snap to top, left, right, bottom edges of a circle, arc

- Multi layers: you could create new layer to draw more items. Layers could be shown, hidden independently.

- Add image: You could add any image file (support file type: gif, jpeg, png, bmp, pict, tiff) to display as an item inside the application.
Image file could be shown in following modes: Stretch / Fit inside bound / Fit outside bound.
The application also allows to DRAG/DROP many image files directly from Finder (or press Cmd-V to paste image from current Clipboard) to current editing window to add them to the diagram.

- Add items (block) to Block Template list:
Right click on selected items then select "Add to template list" to save the block to template list so that you can reuse it later

- Customizable background:
Background color, total size of the diagram could be changed during editing.
Background color also can be set to transparent.

- Open/Save to "*.AAD" file:
AAD (*.aad) is the new file type created only for this application.
Press "Cmd-S" to save current diagram to an AAD file so that you could load it later for editing.

- Capture to clipboard:
Press "Cmd-9" or click on Capture button to export current diagram image to clipboard, then you could paste that image to another application.
Example: Open [Preview] application, press "Cmd-N" to paste above captured image to view or to save to an image file.
Of course, you could paste that image to Excel, Word application too.

Other functions:
- Supports Metric or English units (you could change it in the Preferences dialog)
- Unlimited Undo/Redo (shortcut key: Cmd-Z / Shift-Cmd-Z)
- Copy / Paste (shortcut key: Cmd-C / Cmd-V)
- Group / Ungroup Items (shortcut key: Cmd-G / Shift-Cmd-G)
- Lock/Unlock items position (shortcut key: Cmd-L / Shift-Cmd-L)
- Change display order
- Export to png, jpeg, tiff, pdf image file (shortcut key: Cmd-E)
- Print supported (shortcut key: Cmd-P)

UPDATE they broke this app

I want hobbiest CAD. I want to make simple mechanical drawings for stuff I can build in the garage/basement. My CAD experience is extreemely limited (none in the past seven years). Going from no CAD to SimpleCAD is like being unchained from the cave. I may well outgrow this stripped down package, but for now it’s doing me super. On the first day, I created drawings for a project with the front view on one layer, the dimentions on another, and a few other layers for oblique projections, hardware, and whatnot. It was a struggle at first, but I’ve gotten pretty zippy with it in just a couple days.

The only real problem I have with it, is the help isn’t as helpful as it could be. It’s a .pdf file and I believe it was translated from another language. It’s not a bad translation compared to some I’ve encountered, but it does sometimes lack for clarity. Still, there was nothing I couldn’t figure out by playing with it for a bit.

They broke this App. In the previous version you could set the size of a rectangle in the left text boxes. Those boxes are now gone and new "Size & Position" boxes are located to the right of the drawing. But they don't work. You can't simply specify a rectangle be 3x5


I am a structural engineer who needed a good sketching tool and I found it when I got this program. It still satisfies my needs very well. Again, I say to all people looking for sophisticated CAD features - if you need CAD features, buy very much more expensive CAD programs.

It is 2017 now and I still love the application for my sketching needs. No regret buying a cheap but very useful program for my needs.

It is June 2017 now and still loving this application.

Does what I need it to do

I use this app to put my ideas down before I start building, it is easy to use and gets the job done for me. I dont need a full featured CAD for what I do.
It would be nice if it went to 3 decimal places, but still useable because I can go in and change the Dimensions and type in exact readings.
So far for the price this is the best app I could find.
I like how you can save the drawings as a PDF file, it makes emailing them easy.
The more I use it the easer it gets.
Thanks for making this app available and affordable!!
