Detailed Description
The principles and features of this invention are described below in conjunction with examples which are set forth to illustrate, but are not to be construed to limit the scope of the invention.
A BIM adaptive family-based method for deriving a blanking list of a curtain wall panel is provided, the BIM adaptive curtain wall panel supporting derivation of the blanking list is an adaptive family made based on an adaptive metric conventional model of Revit software, and the family is used in cooperation with shared instance report parameters and item specifications of the Revit software:
(1) if the length of each side and the length of the diagonal line corresponding to each side in the polygon are known, the shape of the polygon can be determined, and shared parameters are created in Revit software according to project requirements, wherein the shared parameters comprise the length of each side, the length of the diagonal line and the number of the panel.
(2) Selecting an adaptive metric conventional model family template in Revit software to create an adaptive family, which is illustrated here by a quadrilateral panel as an example:
1) 4 model points are created to be adaptive, and the system will default to naming these 4 adaptive points as 1, 2, 3, 4.
2) Four adaptation points are connected by a multi-segment model line to form a quadrilateral and is named quadrilateral 1.
3) And respectively placing a model point, namely a point A, a point B, a point C and a point D, close to the four adaptive points in the quadrangle, and picking up a plane determined by the xy axes of the adaptive points by the model points.
4) And marking the point A, the point B, the point C and the point D pairwise by using an alignment size marking function, and endowing parameters, namely 1-2, 2-3, 3-4, 4-1, 1-3 and 2-4 (corresponding to the adaptive points 1, 2, 3 and 4), with the report parameters of the shared instance of the marked line application.
5) And marking the point A, the point B, the point C and the point D with the adjacent side of the quadrangle 1 in an alignment size, giving type parameters, requiring that the parameters marked and given on the same side are the same parameter, and naming the parameter as A, B, C, D (the parameter A, B, C, D is used for controlling the offset of the curtain wall panel and the central line of the curtain wall stile).
The adaptive family made according to the above 5 steps is named as a quadrilateral panel of the curtain wall and is used for drawing the quadrilateral panel of the BIM model curtain wall.
(3) The built quadrilateral curtain wall panel is loaded into a Revit project, and the project detail degree is set as follows: rough, visual style: the line is hidden. Setting A, B, C, D data, arranging the curtain wall panel clockwise (or anticlockwise) and inputting the number of panel, and using the function of capturing the central point of steel structure (stile) by 4 adaptive points of the curtain wall panel, the error can be reduced to below 1 mm.
