Rafter-Purlin Plan - Dimensioning

Display rafter segment angle: Parallel to the ridge and valley rafters, the segment angle of the rafters connected there can be displayed.

Dimension eave and verge lengths in plan: This dimension chain is generated only when the entire roof is shown in a single drawing. The dimension chain measures the length of the eave and verge lines.

Dimension house edge: This dimension chain is generated only when the entire roof is shown in a single drawing. The dimension chain measures the length of the exterior walls or contour lines.

Dimension eaves purlin spacing: If this option is enabled, the distance of the eaves purlins from opposing roof surfaces is dimensioned. If purlin dimensioning for the purlin spacing is also enabled, the eaves purlin spacing will be included in the purlin spacing dimension chain.

Dimension boarding in porch area: This dimensioning generates two dimension chains for each roof surface. Both dimension chains extend across the entire roof surface. The first dimension chain measures all board joints of boards that touch the eave. The second dimension chain measures all points of the contour line between the porch area and the developed (finished) area.

Dimension boarding in developed area: This dimensioning generates one dimension chain for each roof surface. The dimension chain is as wide as the developed area. Because the boarding in the developed area can be very complex, it is not practical to dimension all board joints in the developed area. For this reason a virtual line (not visible) parallel to the eave is generated in the center of the developed area. All board joints intersected by this line are dimensioned.

Purlin dimensioning: Optionally, you can dimension purlin length, spacing, or both. The length dimensioning measures the length of the purlins and the exterior wall edge, reference axis or house contour (depending on settings) that are crossed by the purlin. The spacing dimensioning measures the distance from the purlin leading edge to the reference edge.

Using the switch to the right of the selection list you can decide whether only individual purlins should be dimensioned (check enabled) or all purlins of the roof. If the check is enabled, upon closing the dialog box a prompt will automatically appear to select the desired purlins with the mouse.

Reference for purlin dimensioning: For dimensioning purlin lengths and purlin spacings, the reference edge can be specified here.

Rafter spacing at purlin: This dimension chain measures the rafter spacing and the purlin ends as end dimensions or intermediate dimensions. Additionally, you can decide whether to always dimension only the left edge of each rafter or both edges. Each dimension chain is then placed directly at the dimensioned purlin.

Using the switch to the right of the selection list you can decide whether the rafter spacing should be dimensioned only at individual purlins (check enabled) or at all purlins of the roof. If the check is enabled, upon closing the dialog box a prompt will automatically appear to select the desired purlins with the mouse.

Rafter spacing at eave: This dimension chain measures the rafter spacing, the purlin endpoints and the outermost points of the roof surface as end dimensions or intermediate dimensions. Additionally, you can decide whether to always dimension only the left edge of each rafter or both edges. Only one dimension chain for this rafter spacing is generated per roof surface. Therefore this dimension chain is located below the eave.

Using the switch to the right of the selection list you can decide whether the rafter spacing should be dimensioned only for individual roof surfaces (check enabled) or for all roof surfaces of the roof. If the check is enabled, upon closing the dialog box a prompt will automatically appear to select the desired roof surfaces with the mouse.

Boarding dimensioning for layer: Because boarding can be entered in different layers, the program must know which boarding is to be dimensioned. Select the corresponding layer in this field.

Boarding dimensioning: Here you select the dimension chain type for the boarding dimensionings.

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: With the dimensioning factor you can influence the distances of the dimension chains. The entered value is only a factor by which the standard distances are multiplied. As a rule, even with a factor of 1 (no effect) dimension chains do not overlap. For aesthetic reasons, some users prefer larger distances. In this case increase the factor slightly (e.g. to 1.5).
