Project onto surface from a point source

Daniel O'Connell Oct 26, 2016 12:49 PM

Hi there,

In essence:

I have a point located inside of a closed surface. The surface is non-uniform and consists of overhangs and areas not directly visible from the point.

I am am trying to find the area of the surface that Is direcly visible from the point, i.e. Areas where there is an unbroken line of sight between point and surface.

Application:

I have a machine that sprays water in all directions. It is located inside of a irregular shaped tank. I am trying to find the area of the surface that the water directly hits.

Thanks!

Do you have the "Irregular" Shape in a model??

If it's inside a tank you could split the tank, just add a configuration and a cut extrude, cut up towards the nozzle. From the tip of the nozzle project the spray pattern onto the shape and use a Split Line Curve, add a surface and then measure the area of that surface..

SDRC Ideas has a project-to-point capability (focused projection). I used it only very occasionally when I ran that program, but it was handy as all get out when I needed it. I don't think there is any way to do it in SolidWorks. It is not the same as parallel projection or the same as draft.
