There is a reason I keep putting off the task of cleaning up most of my 'old' models--those projects that I tinkered with for a while before moving on to the next shiny thing:  they are a mess!  But getting this house model to a level where I can display it takes me one step closer to cleaning out my junk! 

This is a model of the house in which my wife grew up.  It's located in the rural Midwest.  A few years ago, I thought it would be a great chance to dig deeper into the Archipack  and ArchiMesh add-ons.  (Note: as-of Blender 2.79, both are natively-included add-ons).  And it was. I learned some good, time-saving uses for each and I learned ways to spend hours without accomplishing anything. :) 

One advantage of getting old models into a presentable state, in addition to simplifying my file system, is the endless opportunities for self-critiquing my modeling skills.  There were several times when , 1) I realized why I grew bored/frustrated with this model, and 2) I learned several inventive ways to not ever do something.   

Another advantage is finding (and usually re-finding) assets that I have scattered all over my hard drive.  In the last year, I've made a concerted effort to consolidate all those assets into a central asset manager.  Although it takes some time to initially set up the asset manager, I save time while working on a project because I can focus on the main project rather than creating (or usually re-creating) assets that I want.  It's like software's version of Ritalin!
