Developer website: Vu Tien Thinh

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 can 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-and-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 "⌘S" to save current diagram to an AAD file so that you could load it later for editing.
  • Capture to clipboard: Press "⌘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 "⌘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.
