00:00In this video, you learn how to design a tube joint with threaded holes and fasteners.
00:07Here you see the two tubes that will be connected with a joint.
00:12The tubes are placed against each other.
00:17Make sure you have the part design workbench selected.
00:22Then create a new body.
00:26Select it, press F2 and rename it to Connector.

00:56The joint will be created inside this new body as a separate object.
01:00Make sure it's selected, highlighted.
01:03Otherwise, double click on it to make it active.
01:05Now hide the second tube and select the end face of the first tube, which is still visible.
01:12Click on the Sub Shape Binder button.
01:17Toggle the visibility of the first tube to see the shape binder you created.
01:24Create a new sketch inside the connector body.
01:29And select the YZ plane, which lays on the end face of both tubes.
01:36Select the external projection tool.

01:46Then you will be able to select the shape binder.
01:58Right-click to exit the external projection tool.
02:02Box select the projected lines.
02:06And toggle Construction Geometry.
02:09Now the lines are not construction lines anymore.
02:14Box select the defined projected lines again.
02:18And select the Offset tool.
02:23Make sure the Add Offset Constraint box is selected.
02:28And the mode is set to Arc.

02:40Select the Pad feature to extrude it.
02:45Set the Mode to Symmetric.
02:48And enter a length of 40 mm.
02:54Make both tubes visible again.
03:00Select the top face of the connector.
03:03And create a new sketch.
03:08Use the Centered Rectangle tool.
03:12Click on the origin.
03:14And drag the mouse.
03:16Enter 25 mm for the horizontal length.

03:24Press Enter to apply.
03:27Right-click to exit the rectangle tool.
03:30Select the lines and make them construction lines.
03:35Now select the Circle from Center tool.
03:39And draw 4 circles on each corner.
03:47Right-click to exit the Circle tool.
03:49Select all circles and make them equal.
03:54The diameter is not so important here because the Hole feature will be used.
03:59Click on Close to exit the sketch.
04:02Now select the Hole feature.
04:06For the Profile, select Isometric Regular.
04:11For the Size, select M6.
04:16Change the Depth type to Through All.
04:20And for the Hole type, select Modeled Thread.
04:24Click on OK to apply.
04:28Now, both sides have 4 threaded holes.
04:36It's time to add the clamping screws.
04:38Go to the Fasteners Workbench or install it.
