shaded display can appear blurry. This is due to a setting Inside Inventor controlling the display of shaded edges in Drawing files. This setting can be controlled by either the document settings, or by editing a registry entry. I'll cover how to change the settings in the document settings in this blog post, and the registry changes in the next post.
When the shaded views in Autodesk Inventor look fuzzy or blurry similar to the picture below, this is due to Inventor using a bitmap for the display of the view.
The other option is to set the “use bitmap” to offline; this causes Inventorto calculate the shaded view display, rather then using a bitmap to display the view. The result is shown below.
To change the settings for how the shaded views are displayed you can edit the document settings. The settings are accessed by going to the “Format” drop down menu, and then selecting “Active Drawing. This opens up the “Document and Settings” for the current file, now select the “Drawing” Tab. On the tab, select the drop down menu for “shaded Views”. Now the shaded views in the current drawing will display without any blurring.
To have these settings present in your templates and available for new drawings, open your template drawing and modify its document settings using the steps here, and then save the file.
