Confirm export image actually saved

[Bartjuan]

This is a bit obscure I know but this is how I work.

I use FormZ and AutoCAD in conjunction (layout is still useless to me - another topic)

 

I will often put renderings into an AutoCAD layout.

If I have the AutoCAD file, with the rendered image ( typically PNG) OPEN,  AutoCAD locks the PNG file.

If I am back in FZ and I re-export an updated image with the same name, formZ appears to write the file but, If I go to the folder, the image has not been updated ( cuz its locked by AutoCAD)

I want to keep the same name because it is a live link in AutoCAD.

 

Is there a way for the FormZ export dialog to recognize that the file is locked and put up a warning the file has not been written to disc.

Hi Bart,

 

You should get a message if formZ is unable to write the file.  Upon first test, this is working fine for us, but we will continue investigating this to see if we can find a case where it is not working.

 

If you just Export an Image, then set it to Read Only Properties, and try to export again, do you reproduce it that way -- or only when it is open in Autocad?

Marking a file Read Only does give the expected response " File is read only..."

 

However, when the file is loaded in an AutoCAD no such message.

 

Autodesk forum info says the file locking is handled by the OS ( windows) not by AutoCAD??

So it seems there is some other. OS based Lock, that FZ is not recognizing.

Hi Bart,

 

Ok, that's strange.   We will look into this further.

I've experienced this as well in Windows. If you have a preview pane open in Explorer the same thing happens when an image file is selected. The file is "locked" at that point and cannot be overwritten.
