How can I do modeling of knee prosthesis in CAD software packages?

What's the best way to measure growth rates in House sparrow chicks from day 2 to day 10?

What's the best way to measure growth rates in House sparrow chicks from day 2 to day 10? Since, the growth curve from day 2 to 10 won't be like the "Logistic curve" it might not follow logistic...

What techniques can I use to determine the miscibility of polymer blends?

The term miscibility refers to the single-phase state in thermodynamics. I do not mean the compatibility of different components. To determine the miscibility I know several techniques such as...

What is involved in morphological changes of SEM images of a substance?

In the sem analysis of CaCO3 nanaoparticles, the morphology images showed spherical shaped particles but the proposed morphology for these type of nanoparticles is trigonal. I prepared the...

Using CATIA and Autodesk Inventor you can able to draw. For Geometric Data get from Medicine students or from medical books.

I have got the geometric data and tried to do modeling, but the shape complexity and unknown curve is creating a problem.

Soliworks can be used to design the knee prosthesis in CAD, if you are using a regular shape. Otherwise I would recommend using programmes like Rhino that allow you to intersect irregular geometries (say, femoral condyles) with regular geometries (say a sphere) and achieve the correct shape you are looking for.

one way is take CT/MRI images and convert them to 3D model. Then perfect shape and couture will come . Softwares like invesalius, 3D slicer, Mimics can be used for this purpose.

If we use Cad software like Creo, inventer, Rhino for contour generation unless we have the mathematical equation govern that contour we will not get perfect shape. so my opinion is take CT/MRI images of the required part and convert them to 3D model
