How to ask effective questions

Asking questions and getting answers is what this forum is all about. Although people are generally very helpful, there are things you can do to improve your chances of getting good and quick answers. Below you will find some suggestions, but don’t think of them as rules and especially don’t think of them as guarantees.

1. Choose a descriptive title for your post
Don’t title your question “ Help! ” or “ I have a problem ” or “ Deadline tonight! ”, but actually describe the problem you are having.

2. Be succinct but clear in your wording
People need to know some details about your problem in order to understand what sort of answers would satisfy you, but nobody cares about how angry your boss or how bad your teacher or how tight your deadline is. Talk about the problem and only the problem. If you don’t speak English well, you should probably post in your native language as well as providing a Google or DeepL translation of your question.

3. Attach minimal versions of all the relevant files
If you have a gh file you have a question about, attach it to the post. Do not expect that people will recreate a file based on a screen-shot because that’s a lot of pointless work. It’s also a good idea to remove everything non-essential from a gh file. You can use the Internalise Data menu option to cut everything to the left of a parameter:

the flow command works on the control point density relation between the base surface and the target surface, make sure that both have the same quantity and similar position, there you will reduce the deformation in the result.
