I have come across this a number of times in supporting customers. Some customers find issues with putting a logo into there template and that when they use there template they get the following error.
The reason why we get this error is the Logo is inserted as a link to the template file and each time you use the template it is then looking for that logo file. This error will occur if:
A) Outside your Project file
B) Deleted from its original location in windows explorer
This is easily resolved.
Firstly open up the template as you would a normal *.ipt or *.iam
In the Model Browser expand Drawing resources and then Titleblocks.
Under Titleblocks right click select “Edit” this will now activate the sketch environment in Autodesk Inventor
Select “Insert Image” from the ribbon Bar (please note the Logo has to a Bitmap)
specify location and select Image.
Now this is the important part ensure that you have the “link” tick box is unticked
Once this is un ticked the image will be embedded in to the template and no more errors
Hope this helps
Cheers ray
