How to create a safe barrier?
In this tutorial, I'll show you how we create a safe barrier. We use it when creating our platforms. I will show the whole process from creating a 3d model to the production process, I will try to show the different details that you need to pay attention to. Some things need to be decided for the country in which it will be installed, these are the things I will point out.

Step 1: Creating a skeleton for frame generator
We go into the mode of creating a part and make a skeleton through a 3D drawing, for example, take a 4.5 meter barrier with 4 legs, the distance between which we take 1 meter. This distance can be changed, but it makes no sense to take less than 0.5 m.
Important:
Height A is fixed and always = 500 mm.
To draw such a skeleton, turn on the "Ortho mode" function (shown by an arrow in the figure)
The height of the entire barrier should be between 1100 - 1300 mm
Rounding corners. This point must be coordinated with production. We do a rounding with a radius of 120.
Save the drawing as a part and create a new regular assembly.

Step 2: Сreate the barrier
Сreate a standard assembly and add the skeleton there from the first step. I additionally make a mate between zero points and two axes so that the part doesn't move, but this is not necessary.
Save detail and insert frame
We always use a round tubes DIN EN 10220 42.4 x 2.6 for the main part of the barrier,
make the lower part of a smaller pipe DIN EN 10220 33.7 x 2.6
Disable the visibility of the 3d drawing and make small changes using the notch function
After that, the barrier is ready. Let's move on to creating a mount. -
Step 3: Сreating a mount
Let's see what they might be :
1) for mounting on the side of the profile
2) for mounting on top of the profile
They are fixed by welding or bolted connection.
We make them in the form of ordinary metal plates with a thickness of 5 mm. Which at the production stage are simply burned out by a laser from sheet metal.
First photo: for side mounting.
The second photo is for the top mount.
This is a regular rectangle, the size of which decide for yourself. Bolts I will use m14. We make 2 identical sinkers for the weld and bolt connection, but if we decide that the connection will be welded, we remove the holes at the stage of creating the production drawing.
The fastening of these plates to the barrier is done only through welding.
We show this only in the drawings, now I make welding in the model just for visualization.

Step 4: Connection with frame
In this part, I will simply show how the welded and bolted connections of the barrier with profiles look like. We indicate welding only on the drawings, here it is just for visualization.
Mounting on the side of the profile:
Bolted connections:
Welded connection:
Mounting on top of the profile:

Step 5: Drawing
If anyone is interested this topic, I am ready to make the second part with a detailed analysis of the drawings for this barrier.
