Drawing point of origin
-
Hi all,
Wonding if anyone can expound on a problem I'm having with the point of origin of a sketchup drawing.
The drawing I am making is of a large piece of property with several houses on it.
The houses are being modeled separately from the site (just for simplicity sake). Then imported as components (and in some cases mirrored) into the "site" model.
When the "source" house models are altered, I'd like to be able to reload them in the "Site" model and this works OK, but when I do this, any rotation of the source models I've done since importing them gets lost and I have to reposition them every time.
Is there a way to reload without having to reposition the source components each time?

I am not completely sure if I understand where and what you rotate that is lost.
If you make a component on site for instance and then export it to further tweak the building, unless you move or rotate it from its axes, it should be reloaded just fine and regardless of the individual instances being rotated, moved or scaled/mirrored in the master model "as components", they should keep all their features.
See the example "Master" file below with 4 instances of the same "Building" (also included). Make any modification on the building file except move or rotate from its axes and then after saving, right click on an instance in the Master file and reload.

You should keep the origin of the house-models at their individual model's origin - typically the bottom front-left corner with the front facade along the X [red] - that way each house has the same insertion point and orientation... and then you can swap components easily too. Imagine that the houses are simple cube shapes with common origins and rotations - you change the rotation/mirroring of Instances NOT the Component definition's entities themselves.
Don't change the rotation of the source-model's geometry - you will get terribly confused...
If you edit an external house-model do not move or rotate its geometry relative to its origin. You CAN relocate a component's origin by changing its axes BUT with external files you'll get confused. Just re-edit the source-file [move, rotate etc] and reload it so that it is right...When you bring these 'source' house-models into a site-model as components the origins [insertion-points] of these components will be as it was in their original files. Place, rotate and even mirror these as needed. If you edit an external house-model and reload it as a component, details in any pre-placed instances might change BUT their rotation or location relative to their insertion points should not... UNLESS of course you have moved stuff in the original house-model file - then it's just doing what you told it to...

Thanks for the replies, mates.
I think I've worked it out with your kind assistance.
Cheers!

guys,
i think i am having a similar problem. a big site where i located 3 buildings which i modeled separately in their own files. however, when they were brought into the big file i had to place them in new positions relative to their previous origins. then i took them back to the original files and pasted them in the same place as they are in the big file (so that moving them back and forth is easier).
problems: in the original files the first origin is never forgotten when i want to have a facade view. in the big file my renderer (podium) does not "see" the buildings.
any ideas?
EDIT: apparently the problem went away after i closed sketchup and opened it again.
