1-First click on the vertical reference icon and select the wall you want to reference. 2-Then enter the wall command. 3-Click the Define local point icon. Select the node for which you want to define the distance or the corner point with the ctrl key. This point (0;0) will be used as the origin point. Press the L key on the keyboard. For example, type 5 and enter to lock the value. When you move the mouse, you will see that 2 points 5 m away from the point you set as the origin can be captured. Fix the point by clicking the left mouse button in the direction you want. 3-Now we are in drawing wall mode. Click on the parallel reference icon and select the object such as wall, axis, line that you want to reference. Press L, enter the wall length, lock the value with enter and click the 2nd point of the wall with the left button. As a second and more practical method; You can draw a line over the wall you want to take a parallel reference and offset this line, for example, by 5 m. Then, for example, you can enter the colon command and activate the nearest point and place it wherever you want on this line. Third, you reference the wall perpendicular and draw a perpendicular wall from its end whose length is the offset distance. Then you define a reference parallel to this line and draw your other objects.
