I have to use ModelBuilder in ArcGIS 10.1 to create a mix of two tools: buffer and select by location. However, I'm supposed to let the user only enter certain information, and have other fields be assumed. For example, I only want the user to fill in the first three fields, and have the Side Type, End Type, and Dissolve Type be the same values all the time:
How would I go about doing this is ModelBuilder?
