Cura Preview Nozzle Image

[daknife 1]

I designed an object with Sketchup and ran it through the solids inspector and got no errors. I then exported an STL file which I loaded into Cura. When I slice it and look at the preview most of the object is gray and there is a grayed nozzle at the top of the image.

 

Does the gray object mean I have a hole that the Solid Inspector in Sketchup missed?

 

What does the grayed out nozzle mean? I can't find any reference to this anywhere.

 

I've attached a cap of the object I'm referring to.

Do you also see the horizontal dark blue line near the bottom of your image?  If you click on the circle and drag it then you will see that nozzle moving around.  There's also a vertical line off the side of the photo.  Drag that and the gray goes away.

 

The gray I think is a minor bug but as soon as you start dragging the thing at the right it is good.

 

Sketchup is not designed to make solids so it's easy to make mistakes in sketchup.  i strongly recommend you do a 2 minute quick scan of this document.  Particularly the part about "reverse faces":

Thanks for the reply. I moved the circles and as you suspected, the gray goes away. I took a look at the discussion about Sketchup. The Solid Inspector does check for reversed faces and will fix them automatically most of the time. My prints have gotten much more reliable with this plugin.

 

I appreciate your comments about the nozzle image. I thought it was some kind of warning/error indicator. I feel much better knowing its not.
