# Floor Plan - Dimensioning

**Post dimensioning exterior wall:** This switch enables special dimensioning for the studs in exterior walls.

**Post dimensioning interior wall:** This switch enables special dimensioning for the studs in interior walls.

**Dimensioning of element boundaries, exterior walls**: When this switch is set and an exterior wall contains elements, a dimension chain is created for this wall. Unless a special layer is selected, the dimension chain begins at the leftmost point of the wall and ends at the rightmost point of the wall. These points are determined from the layer contours, not from the wall body. Therefore, if all layers of a wall do not start at the leftmost end of the wall body, the dimension chain will not start at the leftmost point of the wall body, but correspondingly further inward. The same applies analogously to the end of the dimension chain. The layers to be considered can be controlled: LayersElementDimensioning\_ExteriorWalls

**Dimensioning of element boundaries, interior walls**: The same applies here as described in the paragraph above for the exterior walls. This switch allows the dimensioning for interior walls to be controlled independently of the exterior walls. The same also applies to the layers to be considered: LayersElementDimensioning\_InteriorWalls

**Dimensioning of reference axes**: Each wall has a reference axis (see Manage wall constructions), which can lie at different positions in the depth of the wall. With this dimensioning, the reference axis of each wall is dimensioned. The dimension chain dimensions the start and end point of the reference axis of each wall and, in between, the end points of the reference axes of walls that are connected to the dimensioned wall.

**Exterior dimensioning, connecting walls**: This dimension chain is created for each exterior wall and dimensions the length of the wall and both edges of the connected interior walls. In addition, interior walls are also considered that are not intersected with the dimensioned exterior wall, but end within this exterior wall, or end at most 0.01 m before one of the wall edges (inner edge or outer edge) of the exterior wall.

**Exterior dimensioning, interior walls**: Depending on the situation, this dimensioning creates multiple dimension chains. These dimension chains also lie outside the floor plan, between the opening dimensioning and the dimension chain for the connecting walls. The dimension chains dimension the interior walls that:

* are located inside the building without contact with the exterior walls,
* run perpendicular to the dimension chain and
* are located on the half of the building on which the dimension chains lie.

> The dimensioned interior walls are grouped according to their position in the building so that meaningful dimensions for room sizes are produced. This automatic grouping results in multiple dimension chains.

**Exterior dimensioning, wall offsets**: This dimension chain dimensions offsets in the exterior wall.

**Exterior dimensioning, building dimensions**: This dimension chain dimensions the main dimensions of the building.

**Interior dimensioning of walls:** This switch enables dimensioning of interior walls. It dimensions wall lengths, opening widths, and distances between openings.

**Use core layers for wall dimensioning**: When this option is enabled, only the core layers are considered for wall dimensioning.

**Dimensioning openings in exterior walls**: With this setting, a dimension chain can be created that dimensions the length of each exterior wall and the openings in between. Various options are available:

> **Opening width outside**: With this option, the width of the openings on the outside of the exterior wall is dimensioned.
>
> **Opening width inside**: With this option, the width of the openings on the inside of the exterior wall is dimensioned.
>
> **Axis dimension**: This option dimensions the axis of each opening. It does not dimension the width of the opening.

**Dimension style**: Here you can select the dimension style with which the dimension chains should be generated in the plan. If no dimension style is selected here, the dimension style from the plan template will be used.

**Dimensioning factor**: The dimensioning factor can be used to influence the spacing of the dimension chains. A value greater than 1 increases the spacing; a value between 1 and 0 (e.g., 0.5) decreases the spacing. In general, a factor of 1 is appropriate.

**Layer for dimension boundaries**: In the floor plan, a large number of automatic dimension chains can be generated. The distance of the dimension chains from the building is determined automatically according to fixed rules. It may happen that the distance is not satisfactory and a larger distance is desired. Of course, the dimension chains can be moved manually as desired, but that costs time, and upon recalculation of the layout the situation may change and you start over. There is a simple yet effective solution for this:

* On each side of the building where you want to move the dimension chains, draw a line at the position where the dimension chains should begin.
* Place these lines on their own layer, for example with the name 'DimensionBoundary'.
* In the dialog box for floor plan settings, go to the sub-dialog 'Dimensioning' and enter the layer name on the right side in the field 'Layer for dimension boundaries'.
* Multiple layers can be used, separated by a semicolon.

> The lines are now considered as dimension boundaries and the dimension chains will automatically lie only beyond these lines.

**Additional wall types, ignore in dimensioning**: Using additional wall types, walls can be excluded from automatic dimensioning.

> In the wall construction of a wall, an additional wall type can be selected/entered. In the floor plan layout, in the 'Dimensioning' sub-dialog, you can specify the additional wall types that should be ignored in automatic dimensioning. This allows you to exclude facing masonry or walls for conservatories from the architectural wall dimensioning.

**Layers element dimensioning, exterior walls**: Specify here the layers to be used to determine the start and end points of element dimensioning for exterior walls. From the specified layers, the program determines the leftmost (Xmin) and rightmost (Xmax) point. These then serve as start and end points. In this way, the start and end point of the dimension chain can be influenced by the user.

**Layers element dimensioning, interior walls**: Specify here the layers to be used to determine the start and end points of element dimensioning for interior walls. From the specified layers, the program determines the leftmost (Xmin) and rightmost (Xmax) point. These then serve as start and end points. In this way, the start and end point of the dimension chain can be influenced by the user.
