Section Drawing - Dimensioning

Dimension distances and wall thicknesses: This dimensioning measures the distances and thicknesses of the walls that are perpendicular to the section plane using incremental dimensions. In addition, a separate dimension chain measures the total width of the building (the walls). Both dimension chains are located below the section.

Dimension vertical ceiling distances: Using incremental dimensions, the lower and upper edges of all depicted ceilings are dimensioned. The dimension chain is located at the right edge of the drawing.

Dimension ceiling heights with elevation markers: For each cut ceiling panel, the top edge is dimensioned with a filled elevation marker. The top edge of the finished ceiling is dimensioned with an unfilled elevation marker.

Elevation markers at ridge and eaves of the assembly: These elevation markers are only generated if roof surface implementations were used and are visible. An unfilled elevation marker is created at each cut eaves and ridge line. The elevation markers are always generated on the topmost visible layer board.

Dimensioning of the roof battens: This dimension chain is only generated if roof battens are visible and run perpendicular to the cutting direction. For each roof surface on which battens were cut perpendicularly, a separate dimension chain is generated. The dimension chain runs as absolute dimensioning parallel to the roof surface and measures the upper corner points of the battens.

Dimension purlin spacing: With this dimensioning, the distance from each individual plate to the exterior wall is measured. All other purlins are dimensioned in a common incremental dimensioning. The width and the spacings of these purlins are measured. This dimension chain is located below the section drawing.

Elevation markers at ridge and eaves: An elevation marker is generated at both the upper and lower ends of the rafter. The elevation marker is only generated if the rafter has one or more segments at the affected end that are all perpendicular to the section plane.

Dimension roof overhang: This dimensioning measures the distance from the exterior wall edge (or building outline, if there are no walls) to the outermost point of the rafter on the top side of the rafter. The dimension chain is only generated if the rafter has one or more segments at the lower end that are all perpendicular to the section plane.

Dimension chimney reinforcements: For each alternate timber, the distance to the chimney is dimensioned using incremental dimensions. The point of the alternate timber that has the smallest distance to the chimney is used. These dimension chains are only generated for alternate timbers of chimneys. They are generated only if chimney alternate timbers are visible and lie perpendicular to the section plane and if the chimney itself is visible. If the chimney is not visible, the dimension chains are omitted.

Dimensioning of the collar beams: Only collar beams (member type group: 410, 420) that lie parallel to the section plane are dimensioned. If multiple different collar beams appear in the section, each distinct collar beam receives its own dimension chain. The dimension chain runs parallel to the collar beam. If the collar beam contains no cuts or drillings, the dimension chain is an incremental dimensioning and measures the length of the collar beam. If the collar beam contains one or more cuts or drillings, the dimension chain is an end dimensioning and also measures the length of the collar beam; additionally, the corner points of the cuts and both points of the drilling are inserted into this dimension chain.

Angle dimensioning on inclined members: Components of the component type member or profile member that are neither parallel nor perpendicular to the base plane are provided with an angle dimensioning. Exceptions are battens and counter-battens; these are not dimensioned.

Elevation markers at exterior wall edge -- top of rafter: An elevation marker is generated at the intersection of the exterior wall edge and the top of the rafter.

Elevation marker at exterior wall edge -- top of roof assembly: An elevation marker is generated at the intersection of the exterior wall edge and the top of the roof assembly (topmost layer of the roof surface implementation).

Purlins, elevation markers measure on: Depending on the setting, the height of the top side or the bottom side of the purlin is measured. Additionally, each elevation marker receives supplementary text containing serial number, width, and height of the purlin.

Dimensioning of the notches from: For rafters, this enables dimensioning of the notches and alternate timbers. The dimension chain and the dimensioning of the notches correspond to the notch dimensioning in the single-member plans. These dimension chains are only generated if there are rafters in the section and they lie parallel to the section plane. It may occur that several rafters lie in sequence in a section area; in that case, only the rafter that is foremost in the view direction of the section is dimensioned. The dimension chain is only generated if the rafter has one or more segments at the lower end that are all perpendicular to the section plane. Only the notches on the underside of the rafters are dimensioned.

All alternate timbers (member type group 140) that lie perpendicular to the section plane are dimensioned. The inner point of the alternate timber is inserted in each case. This means: from the lower alternate timber the right, upper point, and from the upper alternate timber the left, upper point.

Longitudinal measure from: In the rafter dimension chain the notches are dimensioned (see above). Here you can set which face wood of the notch should be dimensioned. The options 'plumb face wood' and 'angle-correct face wood' are available.

Collar beams, elevation markers measure on: Only collar beams (member type group: 410, 420) that lie parallel to the section plane and are horizontal are dimensioned. It may occur that several collar beams lie in sequence in a section area and partially or completely overlap. In that case, only the foremost collar beam is dimensioned. Depending on the setting, the elevation marker is generated on the underside or the top side of the collar beam. The elevation marker is unfilled.
