| 0:28 | To record this tutorial, I am using Windows 11 OS and FreeCAD version 0.21.1 |
| 0:38 | To follow this tutorial, |
| 0:41 | Learners must be familiar with the FreeCAD interface. |
| 0:46 | For pre-requisite tutorials, please visit this site. |
| 0:51 | Open FreeCAD. |
| 0:53 | Click on Create new to start a new file. |
| 01:01 | Click on View and select Standard View. |
| 01:05 | Choose Axonometric from the menu and then select Isometric. |
| 01:15 | Notice that the gizmo changes to isometric in the canvas. |
| 01:18 | Click on the Auto icon on the top. |
| 01:22 | It is the tool to select the current working plane. |
| 01:27 | Notice the changes in the left side panel. |
| 01:31 | Click on the Top (XY) option. |
| 01:35 | For isometric drawing, the working plane must be the XY plane. |
| 01:41 | Isometric view is a 2D representation of a 3D object aligned to 3 axes. |
| 01:50 | Let’s draw a cube. |
| 01:52 | Create a rectangle and select it. |
| 01:56 | Go to the Property tab in the left panel. |
| 02:01 | Change the Display mode to wireframe. |
| 02:05 | Scroll down to the height and length form. |
| 02:09 | I will make this into a square of 30 x 30 mm in dimension. |
| 02:17 | Make sure snap end and snap ortho tools are enabled. |
| 02:23 | Draw a line from one of the corners of the square for some length. |
| 02:29 | Select this line and change its length to 30 mm as before. |
| 02:36 | Next let’s make the top face of the cube from the existing face. |
| 02:42 | First select the rectangle object, which has dimensions of a square. |
| 02:48 | Click on the Move tool. |
| 02;50 | Check the box for Copy. |
| 02:54 | Click on one of the corners of the rectangle, hold and drag it upwards. |
| 03:01 | Place it at the end of the line object, when you see the white dot. |
| 03:08 | Then click to set it’s position. |
| 03:12 | Create the remaining edges of the cube by joining the edges as seen. |
| 03:19 | Click on the line tool. |
| 03:22 | Click on the corners of the top face. |
| 03:26 | Then move to the bottom face corner, and snap the line to the corner. |
| 03:35 | When you see the white sign click to set the line. |
| 03:40 | Next let’s make a cylinder. |
| 03:44 | Click on the circle tool, and draw a circle on the canvas. |
| 03:50 | Select the circle and uncheck the box for Filled in the left panel. |
| 03:57 | Type a radius of 30 mm and press the Enter key. |
| 04:04 | Notice that the circle appears as an ellipse in the isometric view. |
| 04:11 | Make sure that the snap center and snap ortho tools are enabled. |
| 04:18 | Click on the line tool again. |
| 04:21 | Draw a line from the center of the circle to upwards. |
| 04:27 | In the property tab in the data panel, scroll down to the length form. |
| 04:34 | Type 90 for the length of the cylinder and press the Enter key. |
| 04:41 | Go to Draw style pulldown in the object style section. |
| 04:46 | Change the line type to dashdot from the menu. |
| 04:51 | Now select the circle and click on the move tool. |
| 04:57 | Check the copy checkbox. |
| 05:00 | Click on circle, hold, move and place it on top. |
| 05:06 | Click to set the position of the top face of the cylinder. |
| 05:12 | Observe the white dot sign of the snap tool at the set position. |
| 05:19 | Enable the snap angle tool next. |
| 05:23 | Choose the line tool. |
| 05:26 | Draw a line from the top face to the bottom face of the cylinder. |
| 05:32 | Do this to form 2 projectors for the cylinder as seen. |
| 05:38 | You may not have sufficient space on the screen. |
| 05:43 | Place the cursor on the canvas and use the scroll wheel to pan on the canvas. |
| 05:51 | Next let’s draw a cone. |
| 05:54 | Click on Edit in the top menu and choose box selection. |
| 05:57 | Move the cursor to the canvas and notice the small selection box. |
| 06:03 | Click and hold the left mouse and select all parts of the cylinder. |
| 06:10 | Notice that 5 entities are checked in the left hand panel and in the canvas. |
| 06:19 | Click on the move tool and check the box for Copy. |
| 06:24 | Drag out a copy of the entities together in the canvas. |
| 06:31 | Select and delete the top face and the 2 side projector lines. |
| 06:38 | Enable the snap angle tool. |
| 06:42 | Then click on the line tool. |
| 06:44 | From the top of the 90 mm line, draw a projector line to the circle. |
| 06:52 | Repeat to add a projector line on the other side as well. |
| 06:59 | Next let’s draw an ellipse. |
| 07:02 | Click on the ellipse tool. |
| 07:04 | Move the cursor to the canvas, click hold and drag. |
| 07:09 | Now the ellipse may look like a rectangle to the human eye. |
| 07:14 | In the left hand panel, change the values for delta x(Dx) and delta y(Dy). |
| 07:22 | Type 50 in the form for delta x(Dx), press the tab key and type 60 for delta y(Dy). |
| 07:32 | Press the Enter key. |
| 07:33 | The value for delta z(Dz) gets highlighted. |
| 07:37 | We will leave the delta z(Dz) as is at 0 mm and press the Enter key. |
| 07:45 | Notice the ellipse on the screen. |
| 07:48 | Now do a box selection for the entities in the cone. |
| 07:53 | That is I am selecting all the entities that make up the cone. |
| 08:00 | Move the cursor to the multiple selected objects on the left panel. |
| 08:07 | Right click to open the context menu and select utilities. |
| 08:13 | Select Add a named group option. |
| 08:17 | Dialog box opens. |
| 08:21 | Add a group dialog box appears. |
| 08:25 | I will type cone for the new name. |
| 08:29 | A new group named cone appears. |
| 08:33 | Click open the tree view for cone and notice all the selected objects under it. |
| 08:40 | Next, let’s learn to export our drawings to user friendly formats. |
| 08:47 | First select the objects that we want to export. |
| 08:51 | I will select the cylinder using box selection. |
| 08:56 | Click on File, Export and a dialog box opens. |
| 09:01 | Choose the type of file first. |
| 09:04 | Click on it. |
| 09:06 | Notice a wide variety of options. |
| 09:09 | amf and 3mf denotes 3D and additive manufacturing formats. |
| 09:16 | The Autodesk DWG 2D format is for exporting in autocad format. |
| 09:25 | Formats such as images and pdfs are also available for the choice of users. |
| 09:33 | Give a file name and path of your choice and click on export to save the file. |
| 09:40 | Pause the video, choose options of your choice and practice exporting. |
