### 4.6.1. ORTO mode - Inserting horizontal and vertical components

The graphical editor facilitates placing horizontal and vertical components when the orthogonal (ORTO in short) mode is enabled. You can also use this mode when drawing sections or polylines.

¨ To enable or disable the ORTO mode:

- Click once on the ORTO box in the lower right corner of the screen.

or

- Press the Alt+Z keys.

The ORTO mode also supports drawing at an angle specified on the “Edit” tab under “File / General data” (F7). This angle is specified as an inclination from horizontal line in degrees.

When the ORTO mode is enabled it is possible to place a horizontal, vertical or a slanting section inclined at the specified angle. This way the parallel arrangement is easily maintained without the need to operate the mouse precisely.

The ORTO mode can be used both for editing rooms with “wall” type components as well as for editing pipe runs / pipe feeds. These components usually have to be placed vertically or horizontally. You can also use this mode when “manually” drawing polylines representing the piping in a HZ

When the ORTO mode is enabled it is not possible to place, for instance, a slightly slanting wall. You can only place a horizontal or a vertical wall. This way the parallel arrangement is easily maintained without the need to operate the mouse precisely.

In the ORTO mode you can define an angle at which the walls, pipe feeds and polylines are aligned. If you specify such an angle, then in addition to vertical and horizontal components, you can also place them inclined at the defined angle. Standard value of that angle is 30º. This angle can be enabled and specified in the “Project options” window.

The orthogonal mode has more uses than just inserting horizontal and vertical pipe-runs. In addition to its basic function it also enables maintaining the arrangement of pipe-runs when moving individual components of the system. When components of the system are moved, the points of pipe-runs are also moved automatically, even though they are not marked so as to maintain the relative arrangement of pipe-run segments.

We will demonstrate the principle of functioning of this mode on two examples:

- Moving a radiator vertically up to the ceiling. The starting arrangement is shown in the drawing below:

- The radiator is clicked with the mouse and moved up. The effect achieved with the ORTO mode enabled and disabled is as follows:

ORTO mode on ORTO mode off

- Note that when ORTO mode is enabled, the pipe-runs are disconnected, the radiator is moved, and then the radiator was reconnected to the riser with the existing riser pipe-runs being split into halves.

- Moving a radiator in an apartment system. The starting arrangement is shown in the drawing below:

- The radiator is clicked with the mouse and moved up. The effect achieved with the ORTO mode enabled and disabled is as follows:

ORTO mode on

ORTO mode off

- Note that in both cases the pipe-runs needn’t have been disconnected. However, with the ORTO mode enabled, the neighbouring point of the pipe-run was also moved so that relative arrangement of the pipe-runs was retained.

! The ORTO mode is also used when polylines are drawn.

In the ORTO mode you can define an isometric view angle to which pipe-runs and polylines may be additionally aligned. If isometric drawing is enabled, then in addition to vertical and horizontal components, you can also place them inclined at the defined angle. Standard value of that angle is 45º. Isometric drawing can be enabled and the angle can be specified in the “Project options” window of the “Edit” tab.
