differences in names between different versions

One of the biggest moves was to make the Maths operators (previously found on Scalar Tab) to work on lots more data types. So now Multiply will work on vectors, thereby making vector multiply redundant.

You can now add colours together using the Addition component etc.

Colour HSL is now AHSV.

If you get stuck try using the "Create" feature by Double clicking a blank bit of canvas or shortcut F4 or Edit Menu> Create. This will bring up a Keyword search window which you can use to narrow down your searches.

 

EDIT: Sorry I forgot to add "Sweep the Knee Johnny!" :)

thanks Danny. That starts to help. However, being new at this and following video tutorials It is hard for me to understand what you mean in your first paragraph. I'm doing an exercise that involves using the multiply vector function which as you say has been made redundant and deleted. So now I'm stuck because I have no idea how to replace that function with whatever new has been introduced. But I guess you have no way of knowing how to help with this unless you have done this tutorials before. 

In case you or anybody here did them. I'm referring to Video #10  "Evaluate surface" from the Basic set from Digital Box.  Basically it's about creating a vector that is normal to a surface, and stays normal wherever we move it across that surface. A "multiply vector" is applied to a "surface Eval" for this

The component that you should use instead of [Vector Multiply] is [Multiplication] found in Math Tab > Operators Panel

Or alternatively you can use [Amplitude] (Vector Tab > Vector Panel) which will set a specific length for your vector despite what the original length is.

that is great!! thanks a lot :)

I keep finding these differences and I cannot continue the exercises. 

  About the grids. Rectangular Grid, before it was P,X,Y,S (left) and G,C,M (right. Now it is P, Sx, SY, Ex, Ey and C,P . Similarly, the Hexagonal and Square grids, same thing. 

It's all very confusing, they don't seem to work the same way as before for what I can see in the videos and experiment myself :S

Grasshopper is Beta Software and by this very nature things change, usually for the better.

This does present a horrible conundrum: do you take the time to create a detailed tutorial so others can learn, to only have to change it the next time there's a release. One particular example of this is the Grasshopper Primer. Andy Payne et al have re-written it on several occasions for it to be out of date before they get a chance to publish.

Also the tutorials you are doing are based on old versions and they best way to achieve the desired results then, might have needed 20 components but now there might be the need for only 5. Somethings were impossible before but are now easy.

By far the best way to learn GH is to ask lots of questions here on the forum.

 

With the Rectangular Grid you now have more control over the size and number of cells. The outputs now don't have a centroid of the cell you will need an extra component something like the Polygon Centre to get this point.

you are totally right Danny, thanks for helping.  These tutorials are my very first steps so i'm still taking baby steps that's why i'm being completely dependent for now. But once I pass this, I'll take off. 
I guess I'll have to start bugging you guys here with more silly things :)

Nicolas, welcome!  Curious to hear about your experience in 3D.  Would be nice to hear about why you are checking out GH and what kinds of features you think could be implemented.  Maybe these are things you see in the other packages you have worked with.

Thanks for the warm welcome Luis!  Well, I started doing 3D as a hobby when I was 17, back in the days of 3D Studio 4 for DOS, throughout the years I became an architect and I ended up doing 3D for architecture for quite a while. I've been through all versions of 3DS Max and I've used Maya and Softimage as well. 
 In the last 3 years though, I started using the 3D apps as an architectural design tool, but you must already know that this it not the main purpose of them. 

That's when a friend of mine introduced me to GH and I was blown away by it. This is like THE perfect thing for design. I'm currently designing a high-rise for a city here in China where I live and it has a very intricate twisting, thus I took the leap and started learning GH, but I think they time it'll take me to learn it will far exceed the time of this deadline so I did the whole model in 3Ds Max, but it was a real pain in the ass moving every individual row of vertices manually, and leading myself but nothing but rudimentary techniques to make it look right, and still, it doesn't look as I want and when having to modify it, it's just another full exhausting day at work. 

Anyway, that's briefly the reason. I'm hoping to learn a lot from here. If you have any essential sources (preferably updated) from where I can push my knowledge do let me know please!

Thanks!!
