Edge of step through point on line of travel

Context toolbar for defining a stair’s line of travel and geometry

The Point on edge of step option considerably facilitates the process of placing the steps along the line of travel. This can be useful if you want to create a three-dimensional Allplan-stair based on a 2D draft or an outline imported as a DXF or DWG-format file.

Allplan creates every step (in accordance with the codes) along the line of travel using a constant value for the tread. Consequently, the position of the edges of the steps may differ from the 2D draft or the outline you have imported.

Example: green = draft

Click EstAuxPt. Click stepSelect the edge of the step which is to be adjusted. Click a point on the line of travelNext, enter a point through which the edge of the step is to pass.

Finally, Allplan creates the step so that it passes through the point you clicked:

Note: Allplan internally generates a step using a fixed value for the width (like the Ldg+ option). The point you click is not a fixed geometric point. Rather, it is used to calculate the step width.
Whenever you make further changes, the edge of the step may move accordingly (for example, if you change the width of the previous step).
To prevent the remaining flight length from being distributed across the other steps (cf. Ldg+), the width of the next step is locked, too, and consequently the following steps remain unchanged.

Tip: The step can be unlocked again at any time. To do this, click Ldg+ -> Ungrp.
