Have not investigated yet that if it is possible to export to Microsoft's propriety formats. Anyway this is in plan to investigate, if possible visio formats will be added to future release.

Thanks jimparkins for liking the app and suggesting the new idea.

The real time collaboration using this app is a killer idea. This was suggested by many people sometime ago (in pre launch demo). But honestly, this feature will take some time to implement.

Thanks darrhiggs..

I was not aware of DOT format. Just now goggled and found the wiki page of DOT. Looks interesting. Probably in next release/update I will add DOT support.

When user completes a stroke (touch up), then I take the path drawn by user, then divide the path such that each small sub path is very close to a line. Then I have combination of lines, Suppose I have four lines, then possibilities are that it can be a quadrilateral or circle, (if the end of last line is close to the start of the first line), then I use variance to determine which shape closely fits to the drawn stroke.

Once I know if this is quadrilateral, then uses various heuristics to find out if it is close to a rectangle or parallelogram etc.

You can export to SVG. These are formats that you can export to: JPG, PNG (transparent background), SVG, PDF and Lekh format. Diagram exported in lekh format can be opened by Lekh Diagram app.

I could not get you exactly asked. Here is a youtube demo of how to connect shapes: http://www.youtube.com/watch?v=EKT_NqHM6Zk

I guess you asked connecting to itself.. right?

for that draw a independent bezier curve. You can easily move and modify the bezier curve by moving it's control points.

I did not understand your Q1 for Q2: Identifying sequence of lines vs identifying bezier curve was toughest problem for me.

Yeah, that is in plan, but it will take some time. Development not started yet.

Hi, I am the developer of this upcoming app. I was doing this in part-time and week-end. It took almost 8-9 months to make this into this state.

rajeevk··on The best way to learn iOS Programming... well its working for me
I started learning ios development around 2 week ago. Initially it looked very alien to me. I already know C, C++, C# and Java but not objective-c. The language itself is easy to learn but learning the framework took some time. Now I am much confident and just started my first app. Probably I will be able to finish my first app in a week.

BTW, I am also new to MAC platform and sometime finding using the MAC itself is tedious. I use windows at work and was using Linux at home. Now using mac at home.
