Solid body shown as surface body in Drawing

[Swarfmaker]

The two attached screen grabs are of the same body and of the same drawing sheet.  The first image shows the part as a solid body with appropriate hatching on the section.  I deleted the section A-A and then without doing anything else I changed my mind and created the section again.  This time the section shows as surface only.  Why?

Hi! The behavior does not look right to me. If possible, please share the file here. I would like to take a closer look. In the meantime, try going to the model -> Modify -> Recompute All. Then go back to the drawing. Does it work now?

Many thanks!

The problem is not linked to the file.  Attached is a screen grab of the model sectioned on the same plane and it is solid.  Just the drawing space version which has the issue.  I have attached another model and its drawing - even more bizarre with partial hatching.

Hi,

To me, this indicated a graphics problem that can show up in multiple effects.
In most cases that I have followed in the forums, updates of the graphics drivers loaded directly from the manufacturer's site led to success.

Hi @Swarfmaker 

Please can you send the links to both of those drawings, so that the team can investigate.

If it is sensitive, feel free to send it directly to me Clint. Brown {a} Autodesk.com

Hi @Swarfmaker 

@g-andresen makes a good point. Please can you also share your graphics diagnostic with me.

In my second example the filler plug is not hatched - but if I repeat the drawing of that filler plug as a single component it is drawn correctly.

Hi @Swarfmaker 

Please can you share your graphics setup with us, as laid out above?

[Swarfmaker]

I think that it is likely to be due to model or drawing graphic complexity issue since removing modelled thread on the filler plug has resolved the cross section display issue.

Anyhow, here are the links to the drawings that have issues.  I had not saved the drawings but have re-done them - thus showing repeatability.  GPU info below those links.

Hi @Swarfmaker 

I've aksed the development team to take a look at this.

Thank you!

@Swarfmaker 

Can you take a look at this "Repaired" geometry and see if it exhibits the same behavior in drawings?

[Swarfmaker]

Hi @TheCADWhisperer ,

Yes, that works fine - well done!  What was wrong with my original file please?
