Problem solved!!!
within the model-Information i found the statistic-window and there I was able to delete
the old components. Directly it was impossible.

Hi there,
in the model of my wooden-framed house are a lot of components, which i can't delete, although they are obsolete. All the new good components i have saved in a local folder.
I don't want to bother the carpenter-company by not exporting a nice clean model.
Any suggestions? Where is the folder of the "In-Model"-components. I work with windows 7 and
sketch up pro 2015.
thanks,
Taipi

thanks again! Bars and battens are tricky, especially within the roof, where they are sloped. What drives me crazy sometimes is push/pull. I will try trim again. Have a nice sunday!

Thanks pbacot, you are right, it is not easy to work on a project (since many, many weeks) beside still learning this pretty good, but complex program. The push/pull tool seems to change the faces of the bars and plates in the wall. They need to be cut clean like it is possible with the subtraction tool, which unfortunately only can handle two solids at the same time.
In my model all bars and plates, which have different dimensions are named components and accurate on a millimeter scale. I need e.g. this part list for comparing prices and offers and ordering the exact sizes.

Hi there,
i am constructing a wooden-framed house and the walls are made out of multipe solids (cladding, slats, bars, plates etc).
The subtraction tool works precisely and fine, but it is awfull timeconsuming to cut the window-hole into each single element. There should be a faster and more elegant way to get it done. Sorry, but I have a deadline and need help as soon as possible.

Thanks from the north of germany, taipi
