Create Guideline (PE)

Plant Engineering > Guideline Tools > Create guideline

HiCAD enables a quick and intuitive creation and processing of guidelines thanks to combined numeric and graphic value input i.e. the display of the guideline points in conjunction with a flexible grid and axes system . When you call the function, the Process c-edge dialogue will be displayed.

The window can be divided into the following areas:

Grid size
Axes
Axes table for the determination of the axes position. By default, three axes directions are defined and activated, running parallel to the active coordinate system. In addition, you can define arbitrary, additional axes. To do this, right-click on an empty row to activate the context menu, and select Insert.

If you have defined a greater number of axes for the routing of guidelines, the identification of a particular axis may be difficult owing to the multitude of axes. In such cases, the deactivation of axes in the axes table is also rather difficult. In such cases you have the option to switch axes on or off that are located in the planes spanned by the axes of the active coordinate systems. If you want to hide axes in a particular plane, deactivate the corresponding checkbox below Plane. Activate the Others checkbox to hide/show axes which are not located in one of these planes.

Coordinates
Coordinates table for the display/input of the c-edge points. The coordinates refer to the active coordinate system in the drawing (World CS or Local CS). Initially, the origin of the coordinate system is suggested as the first point.
Buttons

The graphic display changes with the settings in the window:

Dashed lines indicate the position of the axes.
At the graphic cursor (5), the distance to the previous point and the coordinates in relation to this point are shown for the position of the next point.

Proceed as follows:

Specify the grid size.
Select the axes via activation/deactivation of the appropriate checkboxes.
HiCAD now expects you to specify the value for the first point and overwrite the suggested values: You have the following input options:

Graphic cursor

Click the left mouse button
The point is placed in the next possible position allowed by the axes position (indicated by dashed lines) and the grid size.
Snap options, for example J. Snap options ignore axes and grid.
Point options, for example Mid point between 2 points. Point options ignore axes and grid.

The selected point is inserted in the drawing. In the coordinates table, the original, suggested values are overwritten by the coordinates of the point. In the next row of the coordinates table, the same coordinates are initially suggested for the next point. The function is now ready for the specification of the next point.

Coordinates table
If you double-click on an entry in the table, you can manually enter a new coordinate value. Confirm with ENTER to take over the specified value. If you now move the mouse pointer in the graphic window you will see the point for the new position in the graphic.
Move the mouse pointer back to the coordinates table and place it in the empty space under the coordinate specifications. Right-click and select Insert.
In the next row of the table, the same coordinates are initially suggested for the next point. The function is now ready for the specification of the next point.

In the graphic, a line is drawn from the previous point to the position of the next possible point which is determined by the position of the cursor. You have now the same specification options as for the first point.
Proceed likewise for all following point specifications.
If the point specification mode is still active and you do not want to specify any further points, end the point specification with a right-click on the graphic (one more right-click would confirm the created guideline before ending the function).

The result will look as follows:

You can now process the created guideline further in many different ways. The options are the same as for the Process guideline function:

Buttons

OK	The guideline is confirmed and applied to the layout plan. The window is closed and the function ended.
Cancel	The guideline is rejected and deleted from the graphic. The window is closed and the function ended.
Settings	Besides defining the colour settings, you have the option to determine the position of the grid.
	Save points list of guideline Use this button to save the points list of a guideline. In the created text file the table columns will automatically be separated by tab stops. Select the folder and the file type and enter the file name. Example
	Load points list Use this button to load the points of a guideline from a text file. Please note the following: The table columns need to be separated by tab stops or whitespaces. Empty rows and comment lines will be ignored. A comment line must begin with #. Example of a text file

Please note:

You can influence the grid position via the Settings.
The direction of an axis can also be determined (besides via specification of X, Y and Z value) by identifying two points in the layout plan.

Example:
In the image below, the end points of a cuboid's lower edge are identified.

Place the mouse pointer under the last row of the axes table. Right-click to open a context menu and select Pick. Now identify the two points that are to determine the axis direction. The associated X, Y and Z-values are automatically entered into the table.
