Reverse a List

Hi Rafael

Does this help.

Hello Brenden,

Thank you for your help!!!

Unfortunately it sends me an error when I used the statement "point4.Reverse", "point4" is a list of points.

I'm attaching a picture

Hi Rafael,

This one reminded me of a similar issue I had with some curves.

Maybe you could think of it in another direction.

The points could be ordered by their X values in your case. This would in effect reverse the list. But it also provides future flexibility where you might place points in a random order but need to re-arrange them in a specific order like X, Y or Z direction.

Using a similar approach to that Brenden suggested above this could be achieve with an expression node.

Place an expression node and in the Value field type in:
from V in Point7 orderby V.X

The “V” is not important just a variable so it could be anything I believe

Then just disconnect the wire between the endpoint of Line 5 and connect the expression to this endpoint.

That should fix it up.

I have attached a dgn example

Let me know how you go

Thanks

Hi Wayne,

very nice solution.

Do you know some help-manual where we can find tricks like these?

Hi Ingo,

Thanks

I am asked the same question here in our office. Volker and the community are a very good starting point. I have learnt so much just asking questions here. The other great resource are the SIGs. So much info there every month!

However I am just about to release some videos to our team on GC tips so I will package them up and get them online for everyone to enjoy. I will start a thread in the forum so keep an eye out for it. I am no expert but you might find it useful.

Thanks

Hi Wayne,

thanks for your hints.

I know the forum probably is the best place for getting good advice for tricky problems. But sometimes it probably would help if there was a solid way to get some basics explained.

For anyone following: here are some good ones. But I like just plain text help too - so if anyone has some knowlege of a manual out there please post.

And Wayne I'm looking forward to your video package - any help is appreciated.
