The emergence of intelligent drawing tools that enable parametric design for building elements such as walls, doors, and windows not only greatly accelerates the creation of architectural CAD drawings but also allows for efficient and convenient modifications to those drawings! You can easily make the changes by simply modifying the corresponding parameters of that component, or by dragging the object’s grip points! However, when it comes to drawing cross-sections, due to the varying shapes of components and the complexity of making modifications, the cross-section parametric drawing functions in some specialized software are not yet perfect. Those who are using the latest version of HaoChen Cloud Architecture may have already noticed that there are many new features under the section command group, features that were not available before! These new features include enhancements and additions to existing functions, as well as new innovative highlights. There will be even more surprises in the upcoming HaoChen CAD Architecture 2020 – please stay patient! Next, the editor will explain to you how to use the upgraded profile stair drawing function. Profile stairs can be drawn section by section. Select [Section]—[Section Step], the dialog box shown below will appear, and then start drawing section by section. During the drawing process, pay attention to alternating between cut stairs and visible stairs; where there are floor slabs, rest platforms should no longer be included. Profile steps: They can also be inserted in batches, with three methods for batch insertion available: free insertion, insertion between walls, and positioning via two points. Select [Section]—[Sectioned Stair], and the dialog box shown below will appear. Free insertion: Insertion between walls: Two-point positioning: When performing this operation, it is necessary to determine whether the starting step is a cut step or a visible staircase. If the landing coincides with the floor slab, it may not be necessary to specify a landing. The width of the rest platform can be set in the dialog box. Whether set in batches or drawn section by section, the stairs and flight steps produced are identical. Through the demonstration above, it can be seen that the junctions where the stair treads meet the landing platforms, where the stair treads meet the floor slabs, and where the landing platforms meet the walls are all automatically trimmed, resulting in a perfect integration. Moreover, the stairs created through the above four methods are all new parametric stair objects, and double-clicking on them allows for parametric editing. Parametric editing of flight steps: Regarding the method of drawing sectional stairs, the biggest drawback of traditional methods is that modifying the flight steps requires a lot of work Once design changes are made, designers will have to spend a lot of time on repetitive tasks of “copying” and “cutting”. Intelligent drawing tools, through smart insertion and parametric editing, can help designers significantly reduce the amount of work required for modifications and improve the accuracy of the drawings. Finally, it should be noted that in the demonstrations above, the walls and floor slabs of the section need to be drawn using 【Section Wall】, 【Section Slab】, and 【Line-to-Slab】 from the \"Section Command Group\"; whereas the walls created using the \"Wall Command Group\" cannot be integrated with the sectional stairs. Furthermore, the [Section Beam] option in the section command set can also integrate perfectly with sectioned stairs without any need for cropping; this feature will be presented to you later.
