Edit elements

The Edit elements command allows to edit 2D lines and fittings. This command depends on the type of the selected object. If user directly indicated any line segment, then it will be possible to edit it length by indicating a new end point. If user selects the Edit ("E" key) in the command line then a dialog window will appear allowing user to edit the selected segment parameters. Indicating any fitting will open the dialog box that allows user to edit all fitting parameters.

 

Procedures                                                                       

Line edition

1.    Run the Edit elements  command.

2.    Select the line that you would like to edit.

3.    Specify the ending point for the selected line.

4.    (Optional) Select the Change length („L” key in the command line) option to specify a new length without changing the line insertion angle. Optionally it is possible to select the Delta option to specify the length of the line lengthen (in drawing units) or the Percent option for lengthening the line in percent.

5.    (Optional) Select the Edit option from the context menu or from the command line ("E" key) in order to open the dialog window that gives user the possibility to change line parameters.

Fitting edition

1.    Run the Edit elements  command.

2.    Select the fitting that you would like to edit.

3.    In the dialog window specify new parameters for the selected fitting.

4.    Click the OK button to update the fitting on the drawing.

 

For some fittings it is possible to change their type, for example when editing elbows it is possible to change the elbow into a segmented, two-segmented or to an elbow with an inspection door.

 


Examples of changing the type of fitting

 

When editing fittings user can use the Copy dimensions > option, thank to which in an easy and convenient way he can get dimensions from other elements that are located in the drawing.

 

Changing the system type for lines and 2D fittings

Elements that belong to the appropriate system or installation are automatically located on specified layer. The Edit elements command allows to change the system for individual fittings. System change can also be performed by moving elements into another layer. In CAD programs there are many ways to change object layers. A very convenient way is to use the match properties command:

Example:

To change the system (for example in air condition installation from supply air into exhaust air), user should run the Match properties command, select the source object and then select all objects for which he would like to change the layer into exhaust air installation layer.

Notice:
Circular, rectangular and flex lines that belong to the same system are located on different layers:

 

– circular lines are located on the 2Dx_PRO_xxx layer

– rectangular lines are located on the 2Dx_PRE_xxx layer

– flex lines are located on the 2Dx_PFX_xxx layer

The beginning of layer name (2DL) means air condition, the next part (PRO, PRE or PFX) means line form, and the ending (xxx) means system or installation.
