Broken text after text being extruded I'm making 3D text, I got some problem when I added some text and converted the text to mesh and extruded them, here is the step :
1.Add text
2.Converted to mesh
3.Extruded the text
Followed by the broken text screen cut
I don't know why this happened, I tried to used another way by extruding the text in the object data propertied panel then converted the text to mesh, but another problem found that the top and bottom surface of the mesh is not connected the the mesh, which means a single letter consisted of 3 part, and what is the reason behind this and how to fix this
Thanks for explain to me the reason of the two issues I wrote above
There is no need to convert text or curves to mesh to extrude.
Curves converted to mesh will en up in bad topology most of the time... If there are overlapping segments then you will have errors like the ones shown on the question.
Use the Extrude settings in the Geometry section of the text controls in the properties window.


And please don't use photos from your phone, use screen captures, they are more readable
