Weird un-clickable artifacts when using the 3D > Extrude & Bevel > Isometric tool

[lyndseyninedots]

Hi there,

I'm using Illustrator CC 25.0.1 on OS Mojave 10.14.6

I have been creating some isometric letters by using the extrude & bevel tool.

For some letters (the ones with curves) I'm getting this weird unclicklable artifact appearing and I wonder if anyone can tell me the cause or how to get rid of it?

Can we see your settings, did you apply a bevel? Did you extrude live type or paths?

Did you extrude a pink fill with cyan stroke?

If so try extruding a cyan fill, outline, then change the fill to pink.

[lyndseyninedots]

No, the entire thing was black when I extruded it. No stroke.

[lyndseyninedots]

No bevel applied. Paths were extruded. Path was just a black fill, no stroke.

No shading option was selected. The extrude was set to 150.

Screenshot to show settings:

Apologies, extrude was set to 300, not 150. but it does it whatever the extrude depth.

Please check the expanded version out in the layers panel.

[lyndseyninedots]

Sorry could you elaborate on that instruction please? What do you mean by checking the expanded version out?

[Monika Gause]

The layers panel lists all objects.

Take a look at it and check out if there are objects.

[lyndseyninedots]

The artifacts shown in the screenshot do not show up in the layers panel. They are not recognised as objects.

What happens in View > Preview on CPU?

Coincidentally, I've just thought to do this, and it disappears. What's that all about then?

It now uses the CPU for the screen redraw, which is slow, but accurate. The GPU renders your stuff fast, but sacrifices precision for that.
