Turning a 2D Sketch Into a 3D Component
Suppose you’ve got a 2D sketch for a project. You’d like to make a SketchUp model of it to see what it would look like in 3D. How do you go about this? Photo Match won’t work in this case. The solution is to import the sketch and use it as a texture. Then trace the part of the drawing you’re interested in and use the standard SketchUp tools to develop the 3D view.
In the attached video, I turn the cap rail in this drawing
This video runs about 23 minutes and is quite a large file.
Note: this video was made using version 6 of SketchUp. Version 7 automatically cuts edges that cross other edges. Version 6 didn’t do this. For that reason, I would add the following before making the Bezier curve for the top edge of the rail.
Make the faces with the pencil drawing into a component or group. Then draw the Bezier curve on top of the component. The edges in those faces won’t break the Bezier curve that way.
I used the same method to draw Lonnie Bird’s Pipe Box from the Nov/Dec 2004 edition of fine Woodworking.
As always, feel free to ask questions if you need clarification.
