8. Click the Browse For File button to open the Render Output File
dialog box. Name this file Cabin Rendering Large.tif , and make it
a 24-bit TIF file at 200 dpi. Click OK.
9. Save your drawing and then click the Render button again and wait
a while as the new image renders. With the higher quality and larger
image size, this may take considerably longer to process.
10. When the rendering is completed, look at the file size in Windows
Explorer, and then compare the two images in your image-viewing
software. The larger file is much crisper than the smaller image at
the expense of increased rendering time.
