Using google Sketchup for modeling... With practical examples
I've just been using Sketchup to work out dimensions from an imported picture
I used a top view of a superfly.bmp picture to measure the dimensions...It was imported and used as an image..
Use the dimensions tool to add all the sizes you require.
Then use the tape measure tool across a length...I picked the prop slot then inputted the value I required 9".
You are asked if you want to resize the model.. Select OK..
Your model is resized along with all the dimensions
Since sketchup can import a lot of plan formats or pictures all you need is to add dimensions.
With the sketchup you can then do a complete rescale in about 1 second...not exaggerating here...you use the tape tool to measure just one dimension ...such as the span...then tell it what size you want...and just resize the whole model ..it then shows all the new sizes
A great easy method for resizing any plan since sketchup will import and export in lots of the plan formats ..
there are links here to an older version of sketchup and the dxf/dwg importer
