Decay parameter for LCharge
3 Replies

I noticed that the PCharge component has a parameter for force decay but LCharge does not have the same parameter.  Is there a reason LCharge does not have a decay?Continue

Suggestions for finding volume
1 Reply

I have a model that has some tubing / voids.  I've attached a picture with highlighted blue area that characterizes the area I need to grab.  Are there any suggestions for how I can find the volume…Continue

Right Trigonometry component angel calculating right?
11 Replies

In this simple example I'm just using the RTrig component to get angle A.  However, I must be missing something because it seems like I'm getting the wrong value for A when I change the length of…Continue

How to get current Date and Time
5 Replies

Is there a way to just get the current date or time?    Somewhat like the Calendar or Clock components, but dynamic so that they always return the current information.  The current Calendar and Clock…Continue

"the problem was that with the original one, apart from the A/B switch, when you feed only two triangle sides, it doesn't return the angles"

"No, none of the versions that are build against Rhino6 will work on earlier versions. I'm sorry but this is broken for ever on Rhino5."

"I can second that A & B are swaped in the icon.You mentioned that it'd be fixed in the next Rhino6 release...does that alread ship GH versions newer that 0.9.0076 ?If so, would they be compatible with Rh5 SR13?"

"Give this a try... it's not real clean but it might be the idea you are looking for.  If you load the 3dm file and gh file you could be able to move the point sample slider and move the door around the curve.  I left your previous…"

"I also notice that in your example file you have only 1/2 of the curved door selected.  Is that because the door flexes in the middle?  Or is the curve of the door fixed from chord end-point to end-point?"

Norm Sash replied to mandy lam's discussion How do I move an object along a path?
"Sorry... been swamped...  It looks like you want to take a constant length chord and move the endpoints of the chord on the variable curve.   Are you also wanting to maintain a constant distance of mid-chord to curve?  I hope not…"

Norm Sash replied to mandy lam's discussion How do I move an object along a path?
"I think so... just use the Curve > Analysis > Evaluate Length component.  You can just specify the length (curve units or normalized units) and it will return a point on the curve that is at that length."

David Rutten replied to Norm Sash's discussion Decay parameter for LCharge
"The maths for custom decay was beyond me for line charges. If you know how to compute it I can type up a custom line charge C# component, but I'll need an actual equation/algorithm to implement."
