Having Display Problems with Blocks - Rhino 5 SR1

We're having problems with some inserted block models becoming "ghosts" in Pen and Technical modes. Some blocks disappear while hiding the model behind. Shows up fine in shaded mode. The effected blocks show up ok if their exploded also. I'm at a loss. Some bocks are effected and others not.

Sorry, I'm not finding anything useful so far, I will put it on the bug pile. I see that in Technical, the entire block that I am messing with is drawn (in white) as hidden lines, so I imagine that is related to the Pen problem.

Hi,

Any update on this?  I'm having the same problem. 

Any suggestions as to how to retrieve visibility without re-drawing?  We need pen mode for producing assembly guides.

Thanks,

Nick

The bug isn't fixed yet. I have found a workaround however.

 

Open the referanced rhino file, draw a line in the file. I usually duplicate an edge. Save it and update your blocks where they are inserted. The file may need to be moved to update the graphics or it will look like a wireframe. Just nudge it or drag and undo.

 

It's getting us by until there is a fix.

Hi,

Your blocks are embedded, I suspect. Mine are linked blocks, being a bunch of parts which I use within different models. When I add the curve in the parts file the linked block remains ghosted in the dependent model but also as wireframe in shaded mode, so even worse...

I've tried exporting and re-importing in various formats to try and shake off whatever it is, but no luck there.

I also tried creating a new block from a random object, adding the suspect element and then removing the random object and that sort of works, (I made it work but forget exactly how).  But whatever I do, nothing works for linked blocks.

My blocks are linked as well.

After you update the links, try moving the blocks to fix the graphic issue.

The attached pdf should explain...

You are absolutely right.  I'd seen that moving them did something but having tried endless manipulations I managed not to try that one.

Thanks for that - gets me out of a deep hole, albeit temporarily.
