Rhots: There are some concepts which may help to understand what is happening: What is printed is the screen image and not the model. The display nor your printer under stand model size. They work strictly in pixes / dots per inch; For the fit to page print what you see for page size is not the model but the screen size SU has calculated based on its knowledge of the model ize and the pixels size of your screen settings; SU then uses that information and the printer settings to determine the scaling it must a apply to print the screen to your specified paper size and thus the scaling you see in the left scaling box. BTW I would suggest you toogle the use screen extents several times until the the page size report is consistent. ( I think there is a bug here because this and the zoom extents in the SU window give different results. ) In addition related to your comment about dimensions disappearing check what you have set in the expert dimension dialog box. There is an option of not printing when they get too small. I would suggest you make a simple rectangle model with an aspect ratio consistent with you screen (2d) and then make its size very close to the paper size and check out what is happening including change of print format. Just some thoughts based on what I think I know

Here's one of several solutions. sink.skp

What Thon is saying is that if you have difficulty with any plugin you post in the topic. Rather than creating a new topic. You've a better chance to get direct help from the developer.

Thanks again SK, to answer your question, I just used the "push/pull" method to make my parts. I don't know what "outer shell" is. But now I will go look for it. Rick

Answered my own question. When drawing the lines I was in plan view which made my picks come from the top of the existing walls. So I ended up using a negative value for the wall height, which worked fine to create the wall, but apparently it screws up the opening operation. Thanks, Rick

Another trick is to use the Section Tool, as follows: 'cut' the geometry; map the rectangular cutting plane to any orientation by rotating successively as desired; and, with the rectangular cutting plane selected, Right-Click and choose the option to "Align View" It's a work-around but it does what's necessary. Cheers, . Diego.

As my Father inlaw would say "I got 'er boys". I went back to winzip and noticed the check boxes for "use folder names" and overwrite older files. There were no folders showing so I didn't have them checked. Well that's what I get for NOT thinking...It works perfectly now. THANK YOU FOR ALL OF YOUR HELP!!!!!!!!! I'm sure you will hear from me again as I just started using Sketchup a few days ago. MERRY CHRISTMAS FOLKS!! Rick
