Lines and Objects Hidden But Appear During Pan Command

[clippincott-CL]

I have received an Architectural CAD file to use as a background to my drawing and it is behaving strangely.  I know the Architect uses BIM software called ArchiCAD, so this CAD file was exported from their BIM model.

I have discovered that some of the objects in the drawing are being concealed by something, I don't know what.  It behaves like a WIPEOUT but I can't fine any wipeouts.  I have wipeout frames set to ON.  The only way I know this is happening is the objects become visible during the PAN command.  When I move the drawing around, I can see lines appear all over the drawing where there hadn't been any visible before.

I have attached the drawing file.  Does anyone know what is causing this?

Thanks in advance for any assistance offered.

Hi,

as below attached image this is exactly what i see and there is nothing notice when pan the drawing. please try to open the attached CAD file and see if any changes.

imadhabash,

Unless you made some changes to the drawing I attached, the drawing you posted should be identical to the drawing I posted.  I opened yours and it looked the same to me, still hidden objects only appearing when I pan.

Hi,

>> I opened yours and it looked the same to me <<

it's the same ... i just clean your original drawing . Now is it easy to make a screenshot OR screen-cast that show this invisible items ?  also does the image that i attache it in my previous post appeared correct and match what you see on your screen ?

imadhabash,

The drawing you posted looks exactly the same as the drawing I posted.  I don't know what you did to "clean" the original drawing but it didn't solve the problem.

When I use PAN command or middle mouse button I don't see anything more than without PAN, no new objects are shown.

So that brings me to some questions:

• which type of AutoCAD do you use
• which version of AutoCAD do you use
• which service packs are installed for your AutoCAD
• have you tried to turn off hardware acceleration (command _GRAPHICSCONFIG) to see if the same happens without hw-acc.
• which graphic card do you have installed
• which operating system has your workstation installed

As I can't see any new lines I'm not sure to have my eyes at the correct position to see that behavior, could you be so kind to use Autodesk Screencast (>>>free to download<<<) and record the screen + show us that the link to that recording ... so we can see what you see and concentrate to do exactly the same steps.

Alfred,

I am using AutoCAD 2016 (via Building Design Suite) with all service packs installed on a Windows 7 system.  Hardware acceleration is turned off and I think my graphics card is an ATI Tadeon HD 4800 Series.

Sorry, but I don't have time to make a recording of my actions working in the drawing.  I guess this is not as simple of a fix as I thought it would be.  But your questions made me think of some avenues to research, i.e. object enablers.

Thanks for your assistance.

Hi,

can you please start 2 commands and upload screenshots from both dialogs?

Commands _GRAPHICSCONFIG as well as _ABOUT.

>> made me think of some avenues to research, i.e. object enablers

From what I know there are no object enablers necessary for your drawing as no proxies are inside the file.

>> Sorry, but I don't have time to make a recording 

It's just 5 minutes, but it's up to you 😉

One idea: open that file, create a new file, use command _COPYBASE and _PASTECLIP to copy the existing geometry to the new drawing (IMPORTANT: please use window or crossing selection for the objects to be copied, not _ALL from command line)) ... does PAN then again show mystic lines?

PS: there are 100 wipeouts, maybe you can select them (command _QSELECT) and delete them.

It was the wipeouts.  Now that I've deleted them, the lines that were hidden are visible all of the time.  Thanks, Alfred.
