Endmarks are used to define where the reinforcement bars are starting and ending. This is very useful when there are many bars placed in a location and it is tricky to determine where the different bars start and ends.

Endmarks can be created as any symbol or figure. The following GIF will show how to create an endmark with the shape of a triangle.

One clue thing to remember is that the endmark needs to start in origo (0,0,0). From there you can draw lines to create a shape, in this case, a triangle.
The Grip point determines from where the symbol should attach to the bar. In this example, no offset is chosen for the Grip point. The endmark is then attached to a straight bar with a length of 1000 mm. 

In the following GIF, the same symbol and grip point is used but the offset length is set to 10 mm. As you can see in the GIF, the length of the bar shows 900 mm now. This is because the value of the offset length is multiplied with the scale set for the endmarks and endhooks when a bar is drawn. In this case, it was set to 0.1. The last parameter that affects the final length is the scale of the drawing which is set to 50 in this case.
The resulting length is then 1000 - 10*50*0,1*2 = 900 mm.
1000 - (Offset length)*(Scale of the drawing)*(Scale endmarks and endhooks)* (two, on both sides).
