Is that due to the building curve or how do I detect issues errors with this surface and how to fix this? happened many times in the past. Thank you! Export N Surface.3dm (150.6 KB) [image]

[image] Hannes Grebin: Thought this is a standard font. Well, despite its heritage, it does not appear (for the “N” at least) to be of Swiss quality… :stuck_out_tongue_winking_eye: Seriously, even the most used fonts have problems, I am not even sure if the software packages used to design …

So good. Thank you for this information. Mitch, do you think this is worth a feature request, to have a function to check geometry for bad things/issues that occur during operations like the dots that are created when boolean operations fail. Thank you for your opinion on this. Would be very hand…

[image] Helvetosaur: if you work in wireframe, the mesh is not made immediately, it is only created when you turn on a shaded mode. It may be too late by then. Thanks, Mitch, for explaining this in-depth. Understand now! Will use CrvBoolean in any future case to tackle this. Thank you!

Letterforms are notorious for being bad curves to make surface or volume geometry from. Generally they are made with Illustrator-style programs which throw together a connected collection of Bézier splines without regard to continuity at joints, quality of the curves etc. Nobody really cares about…

This N was Neue Haas Grotesk which is the predecessor of Helvetiva, which is actually Helvetica if you are not zooming in. Thought this is a standard font.
