algorithmic modeling for Rhino
curve side problem
Hi,
I have a problem with my definition, I would like to know where my curve is compared to a point, for example is it left or right to curve.Its important to know so i can orient my next curve accordingly.
I tried with "curve side" but it seems that nothing changed at the output (left, right) when i put the same curve to the right and then to left of point, i also changed the plane but the same problem occurs. I could not find something relevant on internet so it would be helpfull if anyone knows something about it or another way to orient a curve (arc) to a specific point.

Like this?
BTW: A far more sophisticated version of that is available (but using solely code)

just tried to create the beginner version of the sophisticated version.
Think it works so far.
What about the Pro one?

Pro eh? (Good news: sardines on sight, Bad news: far and away).
1. Assume that you want to "exclude" some "unsuitable" points using some options (shown: if the point is outside the virtual region defined by the curve start/end ... discard it).
2. Assume that you want to identify a region of interest (i.e. a BrepFace that contains the point picked).
3. Assume that the curve has some self intersections.
What to do? Answers: The Lord, District 9, North Pole
But first things first: Do that (all curves shown are one curve):

Hi Peter,
tried the Curve Intersection thing,I stumpled a few times over the Array to List/tree whatever error, i still need to understand it completly, cause it occurs quite often.
Other thing i tried because yesterday I needed it:
Have to booleanDiffernce a lot of Geometry( I know thats rhinos forte, but due to lack of ability to use a solidmodeller need to do it there/was watching first tuts for c5 yesterday, hehe).
I want to do it in a loop like this:
I think I can interpretate the error: no list is made since the array returns empty. But dont know how to solve it.Even if I tweak tolerance ridicously high it wont.
Maybe you could fix this ?
Will upload both files.
Thanks man!

oh, think I did an essential mistake, that I need to replace every step in the loop the Brep I want to difference from with the "new/hollowed" one. Will try to understand this also.
BTW Think understand th array thing( do it in a for loop, right?)

Hmm ... close but no cigar (meaning that Da Morgada stuff is fading in the distance).
See attached.
BTW: You can do this with components ... however if you work on a far bigger/complex thingy (real-life) and/or you need a lot of checks (if this, then that) ... etc etc.

looks ways more comlpicated then i thought it would be...will try to get the gist in pause

And this (a gift from the Merciless SardineLord for you [i.e. the brave])... well ... proves the obvious (Compare with the native stuff)
But what actually does this freaky thingy?

And this is the politically correct stuff (Trees, Lists, Arrays, nulls, cats, dogs and the likes)

thanks for this! (but pc?uagh!)
found out how to solid difference, but I realized also it was pointless.
Now I am searching a new way(in a new thread)

With regard the visual indication of the BrepFace containing the point in question here's the once in a lifetime opportunity to win:
(a) 12, (b) 123, (c) 1234 cans of Da Morgada finest (in pure mineral [15W/50] oil).
