Learning Outcomes<\/p>\n\n<\/header>\n

\n\nWhen you have completed this module, you will be able to:\n
    \n \t
  1. Describe and apply the UCS command to locate and orientate the UCS to any location necessary for model construction.<\/li>\n \t
  2. Draw 3D models using the UCS command to locate and orientate the UCS.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n

    Locating the UCS in 3D Space<\/h1>\nIn Module 4, the UCSMAN command and the UCS II toolbar or ribbon were used to locate the UCS at preset orthographic locations on the model. In this module, the UCS command and the UCS toolbar or ribbon will be used to move and orientate the UCS to locations that are required to construct more complicated models. The most useful option is locating the UCS by selecting 3 points on the model. While it is still necessary to use the predefined orthographic UCS locations for model construction, not all models can be built using only them.\n
    \n

    AutoCAD Command: UCS<\/p>\n\n<\/header>\n

    \n\nThe UCS command is used to locate and orientate the UCS on the model or in model space.\n\nShortcut: none\n\n[caption id=\"attachment_258\" align=\"aligncenter\" width=\"244\"]\"\" UCS II Toolbar[\/caption]\n\n[caption id=\"attachment_258\" align=\"aligncenter\" width=\"425\"]\"\" Tool Pull-down[\/caption]\n\n[caption id=\"attachment_258\" align=\"aligncenter\" width=\"226\"]\"\" Home Ribbon[\/caption]\n\n<\/div>\n<\/div>\n

    WORK ALONG: Locating and Orientating the UCS Using the UCS Toolbar<\/h1>\n

    Step 1<\/h2>\nUsing the NEW command, start a new drawing using the template: 3D Layout English.<\/span>\n

    Step 2<\/h2>\nSave and name the drawing: AutoCAD 3D Workalong 05-1<\/span>.\n

    Step 3<\/h2>\nSet the UCS to World. Enter the UNITS command and in the Units dialogue box, set the Insertion Units to Inches. Using the INSERT command, insert the block: AutoCAD 3D Lab 01-1 at the coordinates 0,0,0.\n

    Step 4<\/h2>\nExplode the block you inserted in step 3.\n

    Step 5<\/h2>\nSet the current view to SE Isometric. Your model should appear as shown in the figure. (Figure Step 5).\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"226\"]\"\" Figure Step 5[\/caption]\n

    Step 6<\/h2>\nSet the UCS location to Right. (Figure Step 6)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"222\"]\"\" Figure Step 6[\/caption]\n

    Step 7<\/h2>\nClick the Origin icon and then snap to the end of the line shown in Figure Step 7A. Your model should now appear as shown in the figure. (Figure Step 7A and 7B)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"600\"]\"\" Figure Step 7A[\/caption]\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"222\"]\"\" Figure Step 7B[\/caption]\n

    Step 8<\/h2>\nEnable object snap. Click the 3 Point icon. When prompted, select the end of the inclined line. This is the X0Y0Z0 of the UCS. (Figure Step 8)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"600\"]\"\" Figure Step 8[\/caption]\n

    Step 9<\/h2>\nFor the second point, select end of the inclined line on the right side of the model. This is the positive X axis. (Figure Step 9)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"290\"]\"\" Figure Step 9[\/caption]\n

    Step 10<\/h2>\nFor the third point, select the end of the inclined line on the top. This is the positive Y axis. Your model should now appear as shown in the figure. (Figure Step 10A and 10B)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"266\"]\"\" Figure Step 10A[\/caption]\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"222\"]\"\" Figure Step 10B[\/caption]\n\n
    \n\nAUTHOR'S COMMENTS: <\/strong>Use the 3 Point method of orientating the UCS as much as possible. It is a very easy to use and will speed your model drawing time. The order of selecting the points is important.\n\nPick 1 - The origin or X0Y0Z0.\n\nPick 2 - The positive X Axis.\n\nPick 3 - The positive Y axis.\n\n<\/div>\n

    Step 11<\/h2>\nUsing what you learned in Steps 8 to 10, locate the UCS as shown in the figure. Ensure that the UCS plane lies on the inclined plane. (Figure Step 11)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"222\"]\"\" Figure Step 11[\/caption]\n

    Step 12<\/h2>\nUsing what you learned in Step 8 to 10, locate the UCS as shown in the figure. Ensure that the UCS plane lies on the plane. (Figure Step 12.)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"222\"]\"\" Figure Step 12[\/caption]\n

    Step 13<\/h2>\nClick the World UCS icon. The UCS icon will now be located as shown in the figure. (Figure Step 13)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"600\"]\"\" Figure Step 13[\/caption]\n

    Step 14<\/h2>\nClick the UCS Previous icon and the UCS should now return back to last location. (Figure Step 14)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"300\"]\"\" Step 1[\/caption]\n

    Step 15<\/h2>\nSave and close the drawing.\n
    USER TIP: <\/strong>Before starting to draw any 3D model, it is important for you to pick the best view to start with. The first view you draw is called the Base view. Usually it is the view with the most difficult contour. The more models you draw the easier it will be to select the best Base view.<\/div>\n

    WORK ALONG: Drawing a 3D Wireframe Model by Locating the UCS<\/h1>\n

    Step 1<\/h2>\nUsing the NEW command, start a new drawing using the template: 3D Layout Metric<\/span>.\n

    Step 2<\/h2>\nSave and name the drawing: AutoCAD 3D Workalong 05-2<\/span>. (Figure Step 2A, 2B, and 2C)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"600\"]\"\" Figure Step 2A
    Dimensioned Wireframe Model SE Isometric View[\/caption]\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"300\"]\"\" Solid Model - View from Top.[\/caption]\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"128\"]\"\" Figure Step 2C
    Solid Model - View from Bottom.[\/caption]\n

    Step 3<\/h2>\nIf you are using toolbar menus, you will be using the UCS, UCS II, and View toolbars. If you are using ribbon menus, enable the Home tab.\n

    Step 4<\/h2>\nEnsure that the UCS is located at World. (Figure Step 4)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"88\"]\"\" Figure Step 4[\/caption]\n\n
    AUTHOR'S COMMENTS: <\/strong>Before you start drawing any model, you must first decide which view is the best to start your model. Usually it is the view with the most difficult contour. In this model, the Base view is the Front view.<\/div>\n

    Step 5<\/h2>\nChange the UCS location to Front. (Figure Step 5)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"135\"]\"\" Figure Step 5[\/caption]\n

    Step 6<\/h2>\nChange the current view to Front. The UCS icon should now appear as shown in the figure. (Figure Step 6)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"108\"]\"\" Figure Step 6[\/caption]\n

    Step 7<\/h2>\nSet layer: Model<\/span> as the current layer. Draw the front contour of the model as shown in the figure. Drawing it in 2D is sometimes easier. It could have been drawn in the 3D view also. (Figure Step 7)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"302\"]\"\" Figure Step 7[\/caption]\n\n
    AUTHOR'S COMMENTS:\u00a0<\/strong>It is ok to draw the first view of a model in a 2D view. As soon as you complete the Base view and are ready to copy the objects to make it three dimensional and from that point on, you must draw in a 3D view.<\/div>\n

    Step 8<\/h2>\nChange the current view to SE Isometric. Your model should now appear as shown in the figure. (Figure Step 8)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"221\"]\"\" Figure Step 8[\/caption]\n

    Step 9<\/h2>\nCopy the lines 100 millimeters in the negative Z direction.\n

    Step 10<\/h2>\nOrbit the model slight as shown in the figure. Add the lines as shown in the figure. (Figure Step 10)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"374\"]\"\" Figure Step 10[\/caption]\n

    Step 11<\/h2>\nUsing the 3 Point method, locate the UCS to the top of the inclined plane. (Figure Step 11)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"290\"]\"\" Figure Step 11[\/caption]\n

    Step 12<\/h2>\nUsing OFFSET command, offset the existing lines to locate the centre of the circle and arc on the inclined plane. Change the lines to layer: Construction<\/span>. Insert the circle and the arc and copy them 25 millimeters to the bottom plane. Before you do complete this step, read the User Tip at the end of this workalong. (Figure Step 12)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"376\"]\"\" Figure Step 12[\/caption]\n

    Step 13<\/h2>\nTrim or delete the lines as required. Using the 3 Point method, locate the UCS to the upper incline plane. (Figure Step 13)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"401\"]\"\" Figure Step 13[\/caption]\n

    Step 14<\/h2>\nUsing the OFFSET command, offset the existing lines to locate the centre of the slots on the upper inclined plane. Change the offset lines to layer: Construction<\/span>. Draw the slots and copy them 25 units to the bottom of the inclined plane. (Figure Step 14)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"300\"]\"\" Figure Step 14[\/caption]\n

    Step 15<\/h2>\nUsing the 3 Point method, locate the UCS to the top plane. (Figure Step 15)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"300\"]\"\" Figure Step 15[\/caption]\n

    Step 16<\/h2>\nConstruct the square hole, copy it and trim the lines. (Step 16A and 16B)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"273\"]\"\" Figure Step 16A[\/caption]\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"365\"]\"\" Figure Step 16B[\/caption]\n

    Step 17<\/h2>\nFreeze layer: Construction<\/span>. Change the current UCS to World and the current view to SE Isometric. (Figure Step 17)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"327\"]\"\" Figure Step 17[\/caption]\n

    Step 18<\/h2>\nEnter the UNITS command. In the Units dialogue box, set the Insertion Units to Millimeters. Insert the key: AutoCAD 3D Workalong 05-2<\/span>. It will overlay the model with a magenta model. If it overlays your model perfectly, your model is accurately drawn. (Figure Step 18)\n\n[caption id=\"attachment_321\" align=\"aligncenter\" width=\"312\"]\"\" Figure Step 18[\/caption]\n

    Step 19<\/h2>\nSave and close the drawing.\n
    \n\nMUST KNOW: <\/strong>The 3 Point icon is the easiest method of changing the UCS to lay on a plane. The order of selecting the 3 points is important. The order is as follows:\n
      \n \t
    1. The X0Y0Z0 or origin of the UCS.<\/li>\n \t
    2. The direction of the positive X axis.<\/li>\n \t
    3. The direction of the positive Y axis.<\/li>\n<\/ol>\nEnsure that you enable object snap to snap to existing objects to locate the UCS correctly.\"\"\n\n\"\"\n\n<\/div>\n
      \n\nUSER TIP: <\/strong>If you have to copy existing geometry in the Z direction, an easy way to do it is to use the COPY command and select the objects first (P1 and P2 - Step 1).\n\nTo indicate the copy distance and direction, snap to the ends of an existing line (P3 and P4 in Step 2).\n\n[caption id=\"attachment_291\" align=\"aligncenter\" width=\"300\"]\"\" Step 1[\/caption]\n\n[caption id=\"attachment_291\" align=\"aligncenter\" width=\"300\"]\"\" Step 2[\/caption]\n\n<\/div>\n
      MUST KNOW: <\/strong>The first view of a 3D wireframe model can be drawn in a 2D view. As soon as the objects are copied to make it 3 dimensional, the current view must be changed to a 3D view to complete constructing the model.<\/div>\n

      Key Principles in Module 5<\/p>\n\n<\/header>\n

      \n
        \n \t
      1. Use the 3 Point method of orientating the UCS as much as possible. It is a very easy to use and will speed your model drawing time. The order of selecting the points is important. Pick 1 - The origin or X0Y0Z0, Pick 2 - The positive X Axis, Pick 3 - The positive Y axis.<\/li>\n \t
      2. Before you start drawing any model, you must first decide what is the best view to start drawing first. Usually it is view with the most complex contour. This is called the Base view.<\/li>\n \t
      3. The first view of a 3D wireframe model can be drawn in a 2D view. As soon as the objects are copied to make it three dimensional, the view must be changed to a 3D view before continuing the model construction.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n

        1. Describe and apply the UCS command to locate and orientate the UCS to any location necessary for model construction.<\/li>\n
        2. Draw 3D models using the UCS command to locate and orientate the UCS.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n

          Locating the UCS in 3D Space<\/h1>\n

          In Module 4, the UCSMAN command and the UCS II toolbar or ribbon were used to locate the UCS at preset orthographic locations on the model. In this module, the UCS command and the UCS toolbar or ribbon will be used to move and orientate the UCS to locations that are required to construct more complicated models. The most useful option is locating the UCS by selecting 3 points on the model. While it is still necessary to use the predefined orthographic UCS locations for model construction, not all models can be built using only them.<\/p>\n
