Please attach your Mathcad sheet, not just a picture.

 

Success!

    slide_8.jpgdraw revolved surface using 3D plot. Idea of last out come shape of this. we have to get that shape in that cos(x) : x:= 0,0.1..2pi range. hope you can help.

    The 3D plot you show seems not to be from cosine.

    Furthermore there are so many ways to rotate cos(x) for x from 0 to 2 pi - vertical axis, horizontal axis ...

        I think its better to use the variables you introduced before when creating the mesh

        I'd prefer a vector function over three separate ones, but that may be a matter of personal taste.

         

        Its sad that Prime does not offer a way to quickly switch from the bad looking autoscale view

        to a more meaningful "equal scale" view. In real Mathcad its just one click. Actually it can be done in Prime, but its a lot of manual work and fumbling around.

        Its a pity that PTC is not willing/able to implement a 3D plot which is worth using and would offers at least the formatting abilities we were used from real Mathcad. This sure would still not be state of the art, but at least a huge step forward.
