If your BILD object doesn't have any ".color" directives in it, then the resulting object will be shown using the model-level color attribute, which can be changed in all the normal ways you can change model-level colors. It <i>may</i> be true that parts of the model created before the <i>first</i> ".color" directive will use the model-level color (I'd have to find/read code I didn't write to verify that -- ugh!).</div><div><br></div><div>--Eric</div><br><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 16px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="5" style="font: 16.0px Helvetica"><span class="Apple-converted-space"> <span class="Apple-converted-space"> </span></span>Eric Pettersen</font></p><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="5" style="font: 16.0px Helvetica"><span class="Apple-converted-space"> <span class="Apple-converted-space"> </span></span>UCSF Computer Graphics Lab</font></p><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="5" style="font: 16.0px Helvetica"><span class="Apple-converted-space"> </span><a href="http://www.cgl.ucsf.edu">http://www.cgl.ucsf.edu</a></font></p><br class="Apple-interchange-newline"></div></span> </div><br></body></html>
