spartan19 Posted March 25, 2010 Posted March 25, 2010 Hello!I am trying to make a convex len but I cannot...I made a concave one by intersecting two spheres but i can't imagine how to make the convex one... Quote
fuccaro Posted March 25, 2010 Posted March 25, 2010 Welcome in the forum! Maybe you could try to SUBTRACT a sphere from a cylinder? Quote
kencaz Posted March 26, 2010 Posted March 26, 2010 You could "revolve" a half elliptical profile or arcs depending on what shape your looking for. Here I revolved half an ellipse around the "Y" axis. KC Quote
fuccaro Posted March 26, 2010 Posted March 26, 2010 You are right, Kencaz. The method I suggested is for creating concave lenses Quote
spartan19 Posted March 26, 2010 Author Posted March 26, 2010 Thanks you!I made it by subtracting a sphere from a cylinder! Quote

MikeScott Posted March 26, 2010 Posted March 26, 2010 How about if you Interfere a sphere and cylinder, instead of subtracting? Quote
drifter15 Posted March 27, 2010 Posted March 27, 2010 Try revolve command Draw the upper half of the convex lense and revolve it over the base axis Quote

I tried it!To my opinion is very useful as in subtracting you lose the solid you subtract while here you can use it...It works like the slice command! Thanks you all for your replies!!! Quote
