Triangular pattern

Hi, can anyone help me to get rid of this zigzag part on the edge either by trimming it off or adding more triangular to make it complete? I don’t know why the horizontal part doesn’t have this issue…

It’s pretty obvious really.

Have a try Lunchbox plugin’s Triangle Panels B instead of TriGrid. (8.0 KB)

Thank you for your help!!

My first effort is quite slow due to SrfSplit. I also replaced Scale with Offset Curve because the new smaller triangles along the edge didn’t look right. (11.2 KB)

Then I reduced that time considerably, leaving Extrude as the bottleneck. (17.6 KB)

No plugins, of course.
