00:00In this FreeCAD tutorial, you learn how to model this pet bottle by using tools like Revolve, Pocket and Pattern.
00:13Let's start in the part design workbench.
00:16And create a new sketch for the bottle shape with this button.
00:22Then select the XZ plane to sketch on.
00:30Now select the Polyline tool.
00:37You can zoom out a little if you want to make the sketch a little bigger.
00:41The coordinates provide an indication of your location within the area.
00:47Start sketching the following shape.
00:51Each time you click, a new line will be created.
00:55Create a total of 5 straight lines.
01:04Then press the M key 3 times to create an arc.
01:10Click on the first vertex you created to close the contour.
01:14Right click twice to exit the Polyline tool.
01:20Select the Dimension tool.
01:25Click on this line and drag the mouse.
01:28Click again, enter 18mm and press ENTER to apply.
01:34Make this vertical line 20mm long.
01:40Also add dimensions to these 3 lines.
01:59The sketch is fully constrained which you can see here.
02:04Click on close to exit the sketch.
02:08The sketch of the bottle shape is finished now.
02:11It will be rotated around this vertical axis.
02:14Click on revolution to do this.
02:16It's already rotated 360 degrees.
02:19To show how this tool works, change it to 180 degrees.
02:25You can flip the direction by checking the reversed box.
02:30Change it back to 360 degrees and click on OK to apply.

02:39Thanks!
02:44Now create another sketch.
02:46Select the XZ plane to sketch on.
02:50And click on the circle tool to select it.
02:54Start sketching on the origin.
02:57Enter a diameter of 25mm and press ENTER to apply.
03:01Click on close to exit the sketch.
03:03Select the pocket tool to cut it out.
03:06For the type, select through all.
03:10Check symmetric to plane to cut it to both sides.
03:16Here you can see how that looks.
03:20Click on OK to apply.
03:24Select the pocket in the tree and click on the polar pattern button.
03:33Enter 90 degrees for the angle.
03:37Also select the vertical sketch axis.
03:43It's this blue axis.
03:47Click on OK to apply.
03:52Select these four edges while holding the CTRL key.
04:00Then select the fillet tool.
04:03Enter a radius of 5mm and click on OK to apply.
04:07Now select these four faces while holding the CTRL key.
04:11And select the fillet tool again.
04:14Enter a radius of 4mm.
04:18When you click here for example, you can preview it instead of clicking OK directly.
04:24Click on OK to apply.
04:31Select this edge and go to the fillet tool.
04:36Enter a radius of 25mm and click on OK to apply.
04:43Now click on the top face.
04:46And go to the thickness tool.
04:51The shape will now be hollow.
04:54Enter a thickness of 1.5mm.
04:58Leave the other settings as they are.
05:02Changing these settings can cause some problems.
05:06Such as a very thin wall.
05:10So change it back to arc.
05:14And click on OK to apply.
05:21So the basic bottle shape is finished.
05:25But let's change the appearance, like transparency.
05:32Right click on the body and select appearance.
05:39Here you can change the transparency of the model.
05:41By clicking in the area, you can see how transparent it will become.
05:46Click on the body again to change the transparency to another value.
05:50Click on close to exit the appearance menu.
05:55So the bottle model has been finished.
