Here are some quick tips for creating drawing files quickly from your large assembly files:

IronCAD can create drawings that exclude hidden objects from the creation process. Simply hide the parts you don't want to show in a drawing and select the create drawing button. The following Prompt will appear:

This tool is asking if you want to show the parts that you have hidden in your drawing file, selecting Yes will show the hidden parts in the drawing, and selecting no will leave them hidden, and unselected in the views. Once in the view creation tool, you can see on the left side with the Select Part/assembly button, that the hidden part is not selected in the tree structure. IronCAD will remember your selection for the future, so updates to this drawing will not include the hidden part when you update the view. 

IronCAD also has the ability to create drawings with views to only show selected parts during creation. This process can be done by selecting all the parts you want to show in a drawing, then right click a part, and select Create Drawing from Selection. This process is similar to the hidden parts creation tool, as any updates to the part will not add parts to the view that were not initially selected in the creation process, unless you were to use the Select part/assembly function.
