Disappearing Text

[vweaver]

I have some (single box)tables in my drawings that are referencing measurements on my drawing (Insert field:Object:Measurement). Sometimes I have a formula (ie. =[I]measurement[/I]+.250)

When I initially enter the text/formula, everything works great. When I go to edit (change what dimension I'm referencing, or modify the formula), the text is invisible. I can highlight where the text/formula is, but I can not see what the text says. If I save and reload AutoCAD, the text is there, until I change it, and then again, it disappears if I want to again modify the text.

This is driving me nuts when I need to make multiple edits...ideas?

Using AutoCAD Mechanical 2011 and Windows 7

Screenshot attachment 1 shows what it originally looks like after initial entry

Screenshot attachment 2 shows what I see when I highlight the 'invisible' text in my table after it was edited and re-selected.

Hi,

Could you able to reproduce this behavior on any new drawing ?

What version of AutoCAD Mechanical are you using ?

Try saving this file to a lower version of AutoCAD Mechanical to see whether you could reproduce the problem.

Please send us the drawing file to investigate further.

Looking forward to your reply.

• I attempted to re-create the problem with a new drawing from acad.dwt, but was unable to.  All of my drawings start with our own template.
• Mechanical 2011
• I still get the same problem saving it as an older version type (tried saving as 2006)
• I could not re-create the problem with Mechanical 2012 using the same file.  I tried saving it again (using 2012, saving as 2011), but Mechanical 2011 still would have the problem
• I attached the file named "bug".  On the paper space Tab "SS" There is a box labeled "Partial Slit Size" with the length value 2.813.  This is the length of the line visible in the lower left viewport (layer 20 Paint-Wrap).  If you select the value 2.813, and right click, Edit Field, and select a new objects length (try same viewport, there is another line on the same layer with a length of .688), after selecting the new object, the value will appear in the table.   However, if you go to re-select this value to change the object again, the text will disappear.  The biggest problem with this, is often this table will be more than a value- it will contain a formula, ie.,   [=object length+.250].  When the entire formula is 'invisible'- it makes re-selection of a new object difficult at best.

It appears that it is something to do with a combination of Mechanical 2011, and the way my drawing  is set-up.

Thanks in advance for any help.

Hi,

Thanks for sharing the drawing. However I couldn't able to reproduce the behavior on my 2011 as well. It seems more of a glitch. Can you confirm whether you have both service packs installed for AutoCAD Mechanical. You can download from the link below,

Hope it helps.
