    Extrude curve or surface

    Hi,

    I am playing around with this and when I do the extrude it shows up but there does not seem to be any caps. I should mention that this is text that I am extruding. How can I be certain that there are caps on the text?

    Thanks,

    Ernie

    I think you will have to use the "Planar" surfacing to get a cap on extruded text if you are having a problem with it, did you "Vectorize" your text ??

    If you also want the bottom capped then you could always extrude your new surface down to create a bottom cap.

    Or just select "Along Z axis" instead of "Along Normal", that should do it :-) :-) But it should work OK on either, does here :-) :-)

    No Caps would be an indication that the curves are either non-planar or open.

    I don't use bobcad, but with the systems I do, another common cause I see with extruding fonts is some are self intersecting. So there might be a little curl in your profile somewhere that the cad doesn't really mind extruding as a surface, but is confused when you want to cap or make solid.

    I have had worst case scenarios with specialized fonts that forced me to edit the fonts so I could avoid the open or self intersecting issues. That was worst case, and I would hope very unlikely for most well developed fonts.

    I may be repeating what MadTooler said, as I am not sure I really understood as He is talking over my head a bit , but it's funny I should see this thread this evening as I encountered this just this morning.

    The Chase:
    All that aside, I found if the profiles are not properly chained, I E not connected it will build walls with no cap. So just select trim 2 entities and connect them up and it should cap the walls.
