Dang it. Wrong again. I didn't see the search option because I wasn't logged on at the time. I didn't realize that search wasn't available unless logged on.

Thanks for the tips you folks have offered. I'll certainly look into the edit styles options and Ruby script usage. I thought there might be something to make it a little less painful. The isolation process certainly works, but it can be a large time investment. Although I have repaired the offending areas, I still have no idea how I created it. I may have done something when I was experimenting with Group and Explode. In this case there were no line breaks, so inferences (which I have been using as much as possible) were working. But... somehow I created hollow walls.

I have only casually looked at Ruby, but have not yet pursued it. I figured I should first get very comfortable and proficient with all of the stock SU tools, which I have done this past week. I looked at several 'Cad' solutions before decided that SU was probably at least adequate, and perhaps even ideal for this particular project. Some time in the future I might like to merge SU with a comprehensive Cad program and perhaps even a separate graphics program to make things 'pretty'.

Yes, forums can be very helpful. I was a little confused initially because I didn't find a search option. It was because I was already in the Newbie section, and the search option is only available from the SCF index. As I progress with my project I'm sure I'll need more answers. When I do encounter a problem I don't give up easily. I prefer to muscle through it myself. But, at some point in time you just have to set your pride aside and get some help.

Thanks guys!

Thanks, but I have just figured it out. With everything flat, I couldn't see what was doing causing the problem. By using lines to isolate several areas, I am able to pull them up. Somehow I ended up with some hollow walls. Those are the ones causing the problems. I just couldn't see that when everything was flat.

I have done things such as to insert lines to isolate areas. I've had some success with that process. I thought perhaps someone might have some clever way to make them more apparent.

Yes, I have seen situations where there was a fat line or more. I gather that thin lines are good and fat lines may be a problem. Some times while using that isolation technique, an entire area might turn into heavier lines. I cleverly recognized that as a clue. Some times the flaw is visible when I zoom waaaay in on the suspect line or intersection. On some occasions I have had success by replacing suspect lines or rectangles, even though I could not see what was wrong with them.

I'm not sure how I could have created something out of plane, so I assume everything is coplaner. Is there a way to identify things that are out of plane? Also, everything I've done so far is in one layer. I plan to use layers as I get further into this project. Lots of them.

I guess the most aggravating thing is that even though I take great care, I still create these errors. I'm a bit surprised by these 'loose ends'. I suppose it is something I am doing, or not doing as I draw.

I am created a rather detailed model of my new home. I did not have a cad floor plan to import, so I have been doing it manually. I have most of the first floor completed. I am to the point of using push/pull to lift the walls. Also, I use the paint bucket to give them color, making them easier to see. Unfortunately, as I attempt to either color or pull up the walls, I find there are several areas that simply will not lift. Or, the wrong parts lift. I have invested considerable time trying to locate unclosed or unjoined wall sections, which cause either the paint bucket or push/pull not to work, or work incorrectly. I still have areas that are failing, but I cannot find what is causing the failure. Is there an easy way to locate these anomalies?
