My name is Campbell. I am quite new to grasshopper and am having difficulty with Windrose Analysis legend and text being out of scale. Not sure what to do, could you please help me?

Thank you so much

Nice to meet you!

I want to study surface which concentrate solar light specific location by using grasshopper and ladybug.

But I reached to dead end by oneself, so I found your grasshopper page.

http://www.grasshopper3d.com/group/ladybug/forum/topics/surface-temperature-under-reflected-solar-heat-gain?xg_source=activity

You say, "Using LB we are able to pin point the location of the sunrays hitting the ground after being reflected by the facade "

So Could you tell me how to create facade by using LB ?

Any ideas

cheers

I was a 3 year user of GC - fantastic program but it was just too buggy, non-intuitive, no community and not documented at all so switched to GH. I was RhinoScripting before which is probably easier than VB as a lot of the methods have already been written but... it's not parametric which is a blow to the feedback of generative design.

To start with VB I would go through the Grasshopper Primer v2 - it's got quite a lot of geometry methods explained. Start with generating point collections through loops, then creating nurbs curves, nurbs surfaces, brep, intersections, projections,.... This should give you a handle on the basic operation of scripting.

From here, start building up a library of VB scripts (with attached images) - I find this really helps as you can pull parts of scripts to append to other scripts - rarely I will write a new script from scratch. I keep the scripts (+images) in folders relating to their operations (eg. point collections, fields, utilities, etc.).

You could then start looking at further pushing scripts in the way you handle data - arrays vs lists; subs; functions; case statements; etc.

There's A LOT not documented with GH VB scripting so you can either look to the Rhino SDK documentation on the Rhino site or search the web for general VB methods.
