Dimension Problem?
-
I have been using sketch up for a while and have started using it for woodworking designs. I have spent a great deal of time on a piece recently and when I got all finished and went back to dimension, all of the components are slightly off from when I started. I have gone back a few times and corrected, but they still are off. Is there something I am doing wrong? the dado's and plywood line up but they aren't the same dimensions I started with. I designed every piece in the cabinet as a group or model, and enter all dumensions through the keyboard, but I am very frustrated. It's mostly just a few 64th's off but it really makes it impossible to build from.

Can we see the project?

Hi Woodbutcher, hi folks.
The only thing that comes to my mind is that you have the "Length snapping" turned on in the "Model info --> Units" dialog box.
This may cause unwanted snaps to an invisible grid.
However, you can specify exact measurements in the Dimension Box.
Just ideas.

Indeed, I can understand your frustration. However - from the model, at this phase, it is really hard to tell where it went wrong (Jean might be right). Better than nothing, at least I cleaned it up a bit; oriented faces correctly and close the back of the doors.
There are some minor pieces (stripes) missing in some doors and I would use components instead of groups and the top molding is somehow running across itself in one corner but otherwise it is a nice model.
Now back to your problem: the way you could scale the individual parts correctly is (very simply) demonstrated in this tutorial. There is however a very good plugin that would allow you to do this esily even on complex shapes: FredoScale (watch the video to see its potentials)

I entered every dimension through the dialog box I checked the pieces a bunch of times as I went and it seemed like at the end I went back and the most basic measurement, like the box being 87.5" long was way off. i drew stiles and rails through the dialog box and they are almost all off. I can't understand the benefit between using components versus groups. Any suggestions? Ohh one more thing. what could I have done through the process that would have resized my pieces?

That's what I cannot really imagine. Unless you incidentally scaled something with the Tape measure for instance?

- Once you have a component definition in the model (and no matter how many instances of this same component), SU will always calculate its whatever complex geometry once thus you can save file size.
- Whenever you modify any of these instances, all the other instances will immediately reflect these changes (now imagine texturing these doors one by one - or all at the same time).
- You can export and reload components from/into your model (so if you still had these as separate files, now you could simply reload them).

that's it. I know it, when I got close to finishing I was messing with resizing the cabinet door to fit the opening from the original drawing, I bet i screwed something up with that. I'm sure that's it. I was so careful to check and recheck my dimensions as I was drawing. everything is off, but the panels still fit the dado and that would make sense it I scaled the model by accident. I will sleep so much better tonight.
