Problems solved by technology
Many families are produced too ideally, which is inconsistent with the actual engineering practice, and some family libraries are completely missing, especially for air duct fittings. There are many inconveniences in the modeling process using Revit 2017 software. The main shortcomings are as follows: First, Only elbows aligned with the centerline of the air duct can be generated, and the diameter cannot be changed. If you need a reduced-diameter elbow aligned with the bottom or top of the air duct, you can only add transition pieces and reducers before and after the elbow. T-shaped three Tong and Sitong have the same problem
Second, the turning radius of the three-way and four-way pipe fittings of the air duct is too large, which is inconsistent with the actual engineering practice, resulting in a huge installation space for the air duct and its accessories, and the end of the air duct, which makes it difficult to build a model smoothly

Embodiment Construction
[0031] see Figure 1-Figure 20 As shown, the technical solution adopted in this specific implementation is: it uses Revit2017 software as the basis to create a new family. In order to avoid the complexity of the reference line and reference plane, the family sample files such as "metric air duct T-shaped tee.rft" provided by the software are not used. , directly adopt the most basic "metric conventional model", create several lofting fusions successively, create constraints, and finally set relevant parameters for them to form the required elbows, tees, and cross fittings.
[0032] Working principle of the present invention: the step of making T-shaped tee is as follows: figure 1 , select the metric general model as the family template, and create a loft fusion on the plane as the main air duct; for example figure 2 , the starting point of the lofting fusion path is locked with the front / back plane axis; for example image 3 , measure the path length of the lofting fusion, ...

The invention provides a Revit air duct connector practical family database, and relates to the field of self-built family databases, in particular to a Revit air duct connector practical family database. Revit2017 software is used as a basic newly built family, in order to avoid the situation that a reference plane of a reference line is complicated, family sample files such as 'metric air duct T-type tee joint.rft' provided by the software are not adopted, the most basic metric conventional model is directly adopted, several lofting fusions are created in sequence, constraints are created, and finally relevant parameters are set to constitute required elbows, three-way pipe fittings and four-way pipe fittings. After the technical scheme is adopted, the Revit air duct connector practicalfamily database has the advantages that not only are more abundant sample files obtained and original family databases are improved but also the family database is more suitable for engineering practice.
Description
technical field [0001] The invention relates to the field of self-built family libraries, in particular to a practical family library of Revit air duct connectors. Background technique [0002] In the original family library of Revit 2017 software, there are many unreasonable family libraries in the two major categories of "air duct fittings" and "air duct accessories" belonging to the HVAC category. Many families are produced too ideally, which is inconsistent with the actual engineering practice, and some family libraries are completely missing, especially for air duct fittings. There are many inconveniences in the modeling process using Revit 2017 software. The main shortcomings are as follows: First, Only elbows aligned with the centerline of the air duct can be generated, and the diameter cannot be changed. If you need a reduced-diameter elbow aligned with the bottom or top of the air duct, you can only add transition pieces and reducers before and after the elbow. T-sh...
