Real parts usually have rounded corners and so you may have to use your imagination to project where the 3D surfaces would intersect at an edge. When you are reverse-modeling a part from images you are not using an exact science. It is better than not being able to put pictures into the sketch but there is nothing about it that can be considered precise. Using Sketch Text Sketch text uses TrueType fonts to create text inside a SolidWorks sketch. This means that any TrueType font that you have can be converted to text in solid geometry this includes Wingdings and symbol fonts. Keep in mind that some characters in certain fonts do not convert cleanly into SolidWorks sketches. Sketch text still has to follow the rules for sketching and creating features such as closed contours as well as not mixing open and closed contours. You can make sketch text follow a sketch curve to space it evenly along the curve you can control character width and spacing as well as overall size by specifying points or actual dimensions. Sketch text can also be justified right left centered and evenly as well as reversed rotated and flipped upside down. Figure shows the Sketch Text PropertyManager and some of the possible uses of sketch text. 193 Part II Building Intelligence into Your Parts FIGURE Examples of sketch text Overlapping characters The icons in the Sketch Text PropertyManager are fairly self-explanatory other than the Rotated Text option which rotates individual letters and not the whole string of text. You can use the Sketch Text tool multiple times in a single sketch to make pieces of text with different properties. Each string of text has a placement point located at the lower left of the text. This point can be given sketch relations or dimensions to locate the text. 194
