I am currently trying different solutions with your insight. 

Once I am able to access the working directory I am going to save images from Mechanical. I am using the Graphics.ModelViewManager.CaptureModelView(int index, "PNG") to capture and save my geometry into the working directory. The problem I am running into is that the API automatically saves it as the name created to the view inside Mechanical's Model View Window. 

Is there any way to append to the name saved from using the CaptureModelView. 

For example, the view name is "Open View" and when I use the Graphics.ModelViewManager.CaptureModelView(int index, "PNG") I get the file named

Open View.PNG in my directory. It there a way to append onto this filename while still using the CaptureModelView()?
