Im having problems sealing bezier curves?

[Tekkybot]

hi. i cant figure out how to seal/heal? curves i make with the bezier plugin. for example. i add a bezier plugin, then i draw a curve, then i connect or overlap/loop the the curves but they don't seal up? i must be doing something wrong?

i also notice, that when i rotate the drawn curves, there not really connected, they look connected when first drawn, but unlike a box that you can rotate, these curves aren't in a true 3d space? i think thats my problem. trying to understand how to draw curves in a 3d way. is this this even possible in sketchup?

I think youve got a slight misconception of what the bezier plugin produces within SU (i assume your talking about the @last plugin btw.)

All it does is produce a single element, similar to the arc tool or the line tool. If you want to join multiple beziers together youll need the weld plugin.

I don't know about the @last tool. but I know that fredo6's bezier curveplugin has a button in the toolbar that, when pressed, closes the curve - you start drawing the bezier-curve; then while you are in drawing mode, press the "close loop nicely" button - your curve will be closed. you can still add control-vertexes at this stage (your curve remains closed).

fredo's bezier-curve tool automatically draws on a plane that is defined by the first three points you draw.
you can change to 3D mode however, by simply pressing Ctrl - the solid black rectangle at the tip of the curser changes to a hollow one, indicating that you are in 3D mode.

however, I experienced that it only makes sense to directly switch to 3D mode, if you have points in the existing model, that you want to snap to. otherwise it can be quite difficult to get the vertexes placed correctly in 3D space.
what I often do is to draw the curve in 2D on a horizontal plane and later move the control vertexes up vertically (press the up key on your keyboard when in edit mode to lock the movement to vertical)

hey dude can give me a link. i searched for a good 5 mins on the forums and internet but i cant find the plugin you speak of.

scroll down until you get to bezierspline.zip, thats the one.

thanx guys. gaieus, is this the same plugin remus linked me to?

[remus]

Nope, theyre different plugins. i cant comment on the functionality of the one gai linked, though as i dont use it.

i really dig the fredo one though

Oh, sorry, I wanted to link to Fredo's and didn't even check the link just copied it.

The one I linked to creates surfaces (or grids) based on bezier curves. Great script, too!
