I have a complex model made of many different groups. I want to separate the groups into new sketchup files so I can add more detail to the individual groups. Then I want to export the main model and the individual groups into collada format. and in my OpenGL app I can replace the lowres main file groups with my highres groups dynamically.
How can I copy a group into a new sketchup file and preserve its position in relation to the other groups in the original file?
I would create a datum point in your model (maybe use the main axes position) and draw a line(s) to that point within your various groups. When you bring in those separate groups to a new model you can then register them all by aligning the point at the end of that line to a common datum point, ensuring all groups are in the same relative position. (You can place that line on a layer so you can switch on its visibility.)
Otherwise, if these operations are not done in the same session, the clipboard data wont allow “paste in place” to work.
