Automatic calculation of the distance from one axis to another axis in the plan or elevation plane, calculation of the vertical distance between two different gradients of the same axis and calculation of the horizontal distance between the axes of a panel and a link girder
The various tools can also be selected via the shortcut menu in the Expression column of the variables in the Variation menu of the corresponding structural component.
1. Distance in the plan plane to a second axis - cd2ax ("calculate distance to axis")
The tool is used for a variable (e.g. roadway width) of a structural component along its axis (main axis). Starting from this main axis, the distance to another axis (second axis) in the plan view is then calculated and output.
Note: The terms main axis and secondary axis are used here for illustrative purposes only; there is actually no distinction between these axes in ALLPLAN Civil.
Syntax: cd2ax_Secondary axis(dir,def)
Secondary axis
Name of the axis to which the distance is to be calculated
Attention: When using this tool, the name of this referenced axis must not contain any spaces!
dir (direction)
Value [0.0 or 1.0]
0.0
Distance is measured orthogonally to the main axis
1.0
Distance is measured orthogonally to the secondary axis
def (default)
Value
Defines the distance to be used if the calculation cannot provide a result for geometric reasons (e.g. if one axis is shorter than the other and therefore no point of intersection is available).
For example: cd2ax_Axis2(0.0,8.5)
Calculates the distance in orthogonal direction to the axis in which the function is used, to the Axis2 axis. If the calculation cannot provide a result for geometric reasons, the value 8.5 is used.
2. Height difference to a second axis - cdh2ax ("calculate distance height to axis")
Automatic calculation of the distance in the elevation plane from one axis (main axis) to another axis (secondary axis)
The function is used in the same way as the cd2ax function and calculates the distance between the gradients in the elevation plane.
Note: Please note that the axes in the plan plane must not be congruent in order to use this function. In this case, you would have to move one of the two axes in the plan plane or create a copy of it, which is then used for the tool. (The geometry in the plan plane is irrelevant for the result of the distance in the vertical direction).
3. Height difference to an inactive gradient - cdh2profile ("calculate distance to profile")
This function can be used to calculate the vertical distance (global Y direction) from the active gradient of an axis to another (non-active) gradient of the same axis.
Syntax: cdh2profile_({Gradient2})
Gradient2
Name of the other (inactive) gradient of the axis to which the distance is to be measured
Attention: When using this tool, the name of the referenced gradient must not contain any spaces!
4. Distance in plan to a link girder - cd2g ("calculate distance to (link) girder")
This tool calculates the horizontal distance normal to the axis of a structural component of type "Link girder" from the axis of a structural component of type "Slab" projected into the plan view. The tool is therefore used when assigning variables to a disc and references a link girder.
Syntax: cd2g_({Link girder})
Link girder
Name of the link girder, normal to the axis of which the horizontal distance is to be measured from the axis of the slab in question
