Join curves problem

Hello everyone

I have encountered the problem of join curves. I try to connect the curves in the same list, but the output is not the only one single curve. Is it because there is an error between my curves? How can I solve this problem? Thanks in advance

It worked for me. Not sure why its not working for you. :man_shrugging:

Tolerance I guess

Hi @tianci I have the same problem as you.

As far as I can see, your curves cannot be connected since the start-end points of the curves do not mach.

In my case I am using a tolerance of 10 decimals, however, if you change that to a coarse one such as 1 or 2 it should work as it worked for @Ryan14

thank you for reply, can you teach me how to change the tolerance please?

i knew they have tolerances, how can I ignore or allow that tolerance? please

Within Grasshopper opened go to FILE → Preferences → Display and change the options in that window

Does the tolerance in the rhino doc have something to do with it?

Hmmm I don’t think it works here, you have to change the tolerances in the unit settings of your Rhino file and recompute your Grasshopper definition.

I tried it, it doesn’t work

Here is the rhino doc tolerance setting location.

The one in the gh display settings is only for changing how many decimals are displayed. Not for tolerance as far as i know. I could be wrong about that.

I tried it and it works! So after simplify, the system directly ignores the tolerance between the two points and connects them together, right? So now the end point and the start point are the same point?

Let me check that.

Seems like so.

But, It will not be as accurate as before because you changed you geometry location by a smidgen.

grateful! I don’t need to be particularly precise, and one small question is do I need to adjust this tolerance every time I open a grasshopper file?

I think so. I would recommend making a Rhino template file with a saved tolerance so that you do not have to do that every time.
But you will have to do it if you are opening a file with the incorrect tolerance.
