The model will scale to the correct size and may shift out of view. As shown in the following screenshot, SketchUp will ask, Do you want to resize the model? click on Yes. With Tape Measure, click on the top point of the seahorse's head, then the bottom flat edge of the hook. For this step, the Tape Measure tool is fast and accurate. I want the printed hook to be 100 mm tall overall. Click on the Edit tab and drag the opacity slider down to around 30 percent as shown in the following screenshot: Click on the home icon and then click on the In Model option. Right away, double-click on the image to select it and its bounding edges, and then make it into a Group. To do so, right-click on the image and click on Explode. Let's reduce the opacity of the image to make it easier to draw on. If you draw on the image right now, the SketchUp lines will be hard to see. You want the image to be large enough to see but the exact scale isn't important now. under Files of type, click on All Supported Image Types and under Options, click on the Use as image radio button.Дouble-click on the image or select the image and click on Open to close the Import dialog box, as shown in the following screenshot:Д¬lick near the origin in SketchUp to set one corner of the image, and then move your cursor towards the upper-right side of the screen to set the size of the image. To get started, we need to import the image into SketchUp. Although more complex designs are certainly printable, this will ensure an easy print from the start. For that reason, I'm going to design parallel lines, no overhangs, and no tiny details. I intend for this hook to be printed on a desktop FFF printer. Let's talk about my thought process for this design.

As you can see in the following figure, it's not a great drawing, but rather a starting point:

I then scanned the image into a JPEG file and saved it to my computer. I started by making a pen and paper sketch of my initial concept-a hook-shaped, low-resolution version of a seahorse. But since we're going to 3D print it, we'll make a fun design. In this chapter, we'll create a useful household object, starting from a simple hand-drawn sketch.ДЇor this exercise, let's start with something useful, and somewhat simple. Logos and cookie cutters are some common 3D prints that are made from 2D graphics. Starting with pen and paper, a precise, professionally designed graphic or anything in between, you can quickly make a 3D-printable model. One of the simplest kinds of 3D models starts from a simple drawing. 3D Printing with SketchUp (2014) Chapter 3.
