Vector Software for Drawing and Diagramming [duplicate]
Solution 1:
It may be difficult to get all features into one app but I'll suggest 5. They might have features in common but I'll highlight the ones you're asking about.
- Artboard - Tablet support
- Sketch - Imports/exports to SVG
- Intaglio - Diagramming
- iVinci - Converts from bitmap to vector
- Pencil - Tablet support (mostly suited for animation and cartoons with bitmap and vector drawing, onion skinning, etc.)
All of them should allow
- Editing any component easily after drawing it (layer support)
- Easily add and edit text anywhere (vectorized text is a standard)
- Exporting to PNG (also a standard)
I can't post more than 2 links but you'll find them easily on MacUpdate (all have trial downloads).
Solution 2:
For vector drawing, on both Mac and iPads, iDraw works extremely well. However, it is not for diagramming; no rubber band lines, etc.
From the features you looked for it supports:
- editing existing shapes
- adding text anywhere
- SVG, PNG export (no maps though)
- it has tablet support (
- it can import other images into the drawing but can not vectorize raster images
