Component visible and selectable in Design Mode, but not visible nor selectable in Drawing Mode

[jeanPWW8N]

Hello,

Some weeks ago, I have created the drawing of my assembly without any problem.
I opened up the same drawing today to change some things, only to notice that somehow one of the components in the assembly is not visible nor selectable anymore in the Drawing Mode. Please see below, the component named Pegasus.

 (^ Visible and apparently still fine in the Design Mode)

(^ How it looks like in Drawing Mode when you create a new drawing. The same is visible when I open an existing drawing containing this part. I can click on the Pegasus component, just that it's not shown at all in the drawing and it's missing the arrow to collapse its content.)

I did an geometry change in another component in the same assembly yesterday, which was rather upstream in the assembly, so maybe the funkiness came from there. But I tried with all older versions of this model and strangely see the same results across all old versions, including the version I used to create my previously-normal drawing. I cleared my cache after seeing this happen, but no avail.

If you have any means to resolve this, please let me know. I'm really not sure what triggered this.

Thank you!

Hi,

did you notice the yellow warning in the register?

Hi günther,

Thanks for the reply. I have tried updating, but it unfortunately doesn't solve the problem. You're seeing the yellow triangle in the image because I was trying it through all my old model revisions. All of them contain the error now, even the ones that used to be problem-free.

Hi,

the reason:

In this component there are no solids only faces.

Thicken the faces and it will appear in your drawing.
