| 0:00 | Welcome to the tutorial on Basic Orthographic Drawing. |
| 0:07 | In this tutorial, we will learn to, |
| 0:10 | Set user preference |
| 0:12 | Draw 2D objects with Draft workbench |
| 0:17 | Draw a line |
| 0:19 | Use snap tools |
| 0:22 | Snap a line to the end point of a line |
| 0:27 | About Draft modification tools and |
| 0:31 | Move and copy an object |
| 0:34 | To record this tutorial, I am using |
| 0:36 | Windows 11 OS and FreeCAD version 0.21.1 |
| 0:46 | To follow this tutorial, |
| 0:48 | Learners must be familiar with the FreeCAD interface. |
| 0:53 | For pre-requisite tutorials, please visit this site. |
| 0:57 | I have opened the FreeCAD interface. |
| 01:01 | To create a new exercise, click on File, New. |
| 01:06 | The Workbench option on the top shows start. |
| 01:11 | In the menu option on top, select Draft workbench. |
| 01:16 | The interface menu options change. |
| 01:20 | Go to View then Toolbars in the menu. |
| 01:24 | Make sure that all the tool bar options are enabled in the list. |
| 01:30 | If any option is not enabled click on the left side to enable it as seen. |
| 01:37 | Macro option allows the user to write and install own features. |
| 01:43 | All menu buttons may not be seen on the top as in the video. |
| 01:49 | If so, drag and rearrange them to make them visible for future use. |
| 01:56 | Now click on Edit, Preferences. |
| 02:01 | Preferences window opens. |
| 02:04 | Go to the General tab. |
| 02:06 | Ensure that the styles are appropriately selected . |
| 02:11 | Now choose the units tab. |
| 02:14 | From here you can change the unit system that you desire. |
| 02:20 | For the unit system, I will choose Standard. |
| 02:24 | I will keep the number of decimals as 2. |
| 02:28 | You may change this later on. |
| 02:31 | Next, click on the Draft option on the left side panel. |
| 02:36 | In the General setting tab, make sure the default working plane is selected. |
| 02:43 | I will select XY top. |
| 02:46 | We can also select this view using the gizmo on the interface as seen here. |
| 02:53 | Internal precision level can be changed based on user preference. |
| 02:59 | I will leave it as is for now. |
| 03:02 | Now go to Grid and snapping tab. |
| 03:06 | I will uncheck the Grid options as seen here for ease of drawing later on. |
| 03:13 | Click on Apply to accept the changes and then on OK to close the window. |
| 03:20 | Now click on View, then on Panels. |
| 03:24 | Make sure Report View and Combo view are checked or selected. |
| 03:30 | Stepwise procedure and any bugs will be shown here by FreeCAD. |
| 03:36 | Model shows the tools used during drawing. |
| 03:41 | The Property View window shows the properties of the object that can be changed. |
| 03:48 | Click on the cube or the gizmo icon as seen. |
| 03:53 | The drop down prompts the user to make 2D, 3D or another selection. |
| 04:00 | Select orthographic or isometric as desired. |
| 04:05 | Orthographic gives 2D drawing and isometric is projection of 3D drawing. |
| 04:12 | For now I will select Orthographic. |
| 04:16 | I will also select the top view. |
| 04:20 | These can also be accessed from the View menu on the top. |
| 04:25 | First click on the Snap ortho tool. |
| 04:29 | When the snap tool is enabled the icon background changes to cyan color. |
| 04:35 | Now let’s draw a Line on the canvas. |
| 04:39 | Snap tools aid the user in selecting specific points on an object. |
| 04:45 | They can be start point, end point, mid point, intersection or perpendicular. |
| 04:52 | Make sure that the Lock icon is disabled. |
| 04:56 | Now the Report view panel prompts the user to pick the first point. |
| 05:02 | The options in the Draft creation tools can be used to choose Line. |
| 05:08 | Notice the changes on the panels on the left side when we click on the line tool. |
| 05:15 | Left click on the canvas, hold and drag to draw a line as desired. |
| 05:21 | Click again to end the line. |
| 05:24 | You can change the length of the line from the task tab in the Combo View panel. |
| 05:32 | At this time notice the coordinates on Combo View changes. |
| 05:38 | Since this is a horizontal line, only x coordinate changes. |
| 05:43 | The exact dimension of the line can also be specified here. |
| 05:49 | You may pause the video and do the following. |
| 05:53 | Add another line by giving x coordinate dimension as 100 mm. |
| 06:00 | Notice a blue small + sign, which indicates that the snap ortho is on. |
| 06:08 | It aids in drawing a horizontal or vertical line. |
| 06:12 | Let’s draw another line which will snap to the end of the first line. |
| 06:18 | Next enable the Endpoint and Midpoint icons in snap tools. |
| 06:24 | Now place the cursor close to the end of the first line. |
| 06:28 | Notice the white dot at the end of the line. |
| 06:33 | Now the snap tool will snap the new line to this point. |
| 06:39 | To save the file, click on File, Save. |
| 06:44 | Now the two line objects can be seen in the list. |
| 06:48 | To select an object click on it and notice the green outline. |
| 06:53 | We can also select an object from the Combo View. |
| 06:58 | Next, we will use Draft modification tools. |
| 07:02 | To move the object, first click on the 4 direction arrow. |
| 07:07 | Many parameters can be tracked during the move in the combo view panel. |
| 07:13 | First click on the object and move the mouse to the new location. |
| 07:19 | Left click again to the desired location, to move the object. |
| 07:24 | To make a copy of an object, first select it. |
| 07:30 | Click on the check box for Copy. |
| 07:33 | Notice the duplicated object name appears on the combo view panel. |
| 07:39 | The new object is superimposed on the parent and is indistinguishable. |
| 07:45 | Now select it and click on the Move tool. |
| 07:48 | Then, place the cursor on the object and move it to the desired location. |
| 07:54 | Save your work as needed. |
| 07:57 | Use File, Exit to close FreeCAD. |
| 08:01 | Now let's summarize. |
| 08:03 | In this tutorial, we, |
| 08:04 | Set user preferences before starting to draw |
| 08:09 | Used Draft workbench to draw a line |
| 08:13 | Used snap tools to snap a second line to it’s endpoint and |
| 08:19 | Moved and copied an object |
| 08:22 | For assignment activity, please do the following. |
| 08:26 | Draw a rectangle |
| 08:28 | Draw a square with a side of 30 mm |
| 08:32 | Next let’s construct concentric circles with the following steps. |
| 08:38 | Draw a circle |
| 08:39 | Click on Snap Center (ON) |
| 08:42 | Click on Point icon in Draft creation tools |
| 08:47 | Move cursor close to the circle and notice the center point appear |
