You'll need to form a series of offset planes. One plane where you want each of the profiles to be.
Create a sketch on the plane
Select all of the model faces (just click one face, then press Ctrl +A).
Now use the Intersection Curve command. The edge of any model face that intersects with the sketch plane will be converted into sketch geometry.
Afterwards, you'll make a drawing of your model. You'll need to hide the part file, and just show the sketches.
I mean how can I have plan like picture 1 ?
the plan with angle on line ( pic 2)

Sarah, the idea of this site is helping people, not selling a software package. You could post a step by step tutorial on how to solve this problem in Solidface. It would at least be in the spirit of helping, but I doubt it would help much since H.Rouzbeh was looking for help with SolidWorks.
