The servo axis is pointing upwards and supported by the robot&#8217;s base, so they need a hole to fit in.

First, let&#8217;s draw the circles for the holes for the screws:<\/p>\n<p>circle<\/p>\n<p>5.9,30.6<\/p>\n<p>2<\/p>\n<p>circle<\/p>\n<p>5.9,2<\/p>\n<p>2<\/p>\n<p>Then, we need other two circles to draw the gears:<\/p>\n<p>circle<\/p>\n<p>5.9,22<\/p>\n<p>5.9<\/p>\n<p>circle<\/p>\n<p>5.9,16.1<\/p>\n<p>2<\/p>\n<p>Now, you can introduce the command &#8220;arrc&#8221; and select as centre the point 5.9,22, a point belonging to the circle of radius 5.9 and as initial and final angles the points where it intersects with the other circle. Once the arc has been created, you can delete the original circle. Repeat this process to create the other arc. You can use the tool to create a polyline from segments to join them all together as the same object. Finally, you can write a text and add dimmensions too.<\/p>\n<p>Here, you can download the solution:<\/p>\n<p style=\"text-align: center;\"><div class=\"\"><a href=\"https:\/\/dyor.webs.upv.es\/qcad\/dxf\/servo_cotas.dxf\" target=\"_self\" class=\"emd_dl_green_dark\" download>QCAD Servo<\/a><\/div>    <style>            \r\n    .emd_dl_green_dark {\r\n        -moz-box-shadow:inset 0px 1px 0px 0px #caefab;\r\n        -webkit-box-shadow:inset 0px 1px 0px 0px #caefab;\r\n        box-shadow:inset 0px 1px 0px 0px #caefab;\r\n        background:-webkit-gradient( linear, left top, left bottom, color-stop(0.05, #77d42a), color-stop(1, #5cb811) );\r\n        background:-moz-linear-gradient( center top, #77d42a 5%, #5cb811 100% );\r\n        filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#77d42a', endColorstr='#5cb811');\r\n        background-color:#77d42a;\r\n        -webkit-border-top-left-radius:0px;\r\n        -moz-border-radius-topleft:0px;\r\n        border-top-left-radius:0px;\r\n        -webkit-border-top-right-radius:0px;\r\n        -moz-border-radius-topright:0px;\r\n        border-top-right-radius:0px;\r\n        -webkit-border-bottom-right-radius:0px;\r\n        -moz-border-radius-bottomright:0px;\r\n        border-bottom-right-radius:0px;\r\n        -webkit-border-bottom-left-radius:0px;\r\n        -moz-border-radius-bottomleft:0px;\r\n        border-bottom-left-radius:0px;\r\n        text-indent:0;\r\n        border:1px solid #268a16;\r\n        display:inline-block;\r\n        color:#306108 !important;\r\n        font-family:Georgia;\r\n        font-size:15px;\r\n        font-weight:bold;\r\n        font-style:normal;\r\n        height:41px;\r\n        line-height:41px;\r\n        width:250px;\r\n        text-decoration:none;\r\n        text-align:center;\r\n        text-shadow:1px 1px 0px #aade7c;\r\n    }\r\n    .emd_dl_green_dark:hover {\r\n        background:-webkit-gradient( linear, left top, left bottom, color-stop(0.05, #5cb811), color-stop(1, #77d42a) );\r\n        background:-moz-linear-gradient( center top, #5cb811 5%, #77d42a 100% );\r\n        filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#5cb811', endColorstr='#77d42a');\r\n        background-color:#5cb811;\r\n    }.emd_dl_green_dark:active {\r\n        position:relative;\r\n        top:1px;\r\n    }<\/style><\/p>\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Sorry, this entry is only available in Espa\u00f1ol.<\/p>\n","protected":false},"author":1,"featured_media":1004,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[12],"tags":[14,31,27,25],"class_list":["post-972","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-qcad","tag-dyor","tag-qcad","tag-robot","tag-servo"],"aioseo_notices":[],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/dyor.webs.upv.es\/wp-content\/uploads\/2017\/02\/servo_cad.jpg","jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":1030,"url":"https:\/\/dyor.webs.upv.es\/en\/diseno-qcad-de-un-servo-360o\/","url_meta":{"origin":972,"position":0},"title":"QCAD Design of a 360\u00ba servo","author":"soporte","date":"Friday February 24th, 2017","format":false,"excerpt":"The purpose of this entry is to describe necessary steps to design a basic CAD model of a 360\u00ba servo, based on FS90R, that will be placed at the bottom of the base of DYOR Robot.
