Harold Black Mar 7, 2018 10:32 AM (in response to William Gilbert)What is the curve that defines the object if you were to take a crosssection on the xz plane?

Craig Schultz Mar 7, 2018 10:38 AM (in response to William Gilbert)Draw on the right plane (perpendicular to y) using curve through points, Extrude the shape longer than you need.
Do the same on the top plane (perpendicular to z) Uncheck the merge box in the extrude feature.
Combine > common

Re: How to make 3D object using integrals and reference equation of base shape?
Harold Black Mar 7, 2018 10:43 AM (in response to Craig Schultz)So my understanding is that the cross section shape on the xz plane is a semicircle from x=2 to x=2 and going up to z=2?



Re: How to make 3D object using integrals and reference equation of base shape?
Harold Black Mar 7, 2018 10:57 AM (in response to Anthony Kanov)That is what I was trying to get at. He needed to explain what the defining equation was for the other direction.

Re: How to make 3D object using integrals and reference equation of base shape?
William Gilbert Mar 8, 2018 8:04 AM (in response to Anthony Kanov)Thank you for the help. The problem for me is that I have no defining equation as the curve is defined by the infinite crosssections (integral), so I have nothing to plug in. Is there another way to make the object I included in my image by using such crosssections?

Harold Black Mar 8, 2018 8:10 AM (in response to William Gilbert)What determines the height of each of the squares? You have equations to define the x and y values (the circle) but what defines the values for the z direction?

Re: How to make 3D object using integrals and reference equation of base shape?
Anthony Kanov Mar 8, 2018 8:36 AM (in response to William Gilbert)I suppose the integral is a proprietary information. One way to go about it is to use an approximation. Google Riemann sum perhaps. You could also get a curve through defining points imported from a text file (excel). The problem is more mathematical than CAD.




Re: How to make 3D object using integrals and reference equation of base shape?
Harold Black Mar 8, 2018 8:36 AM (in response to Per Engberg)That's what I was thinking, but without more details about how the height was defined I didn't want to assume and give a wrong answer.

Per Engberg Mar 8, 2018 8:42 AM (in response to Harold Black)I have no problem assuming :)
