In the process of CAD mechanical design, we often encounter situations where it is necessary to create new parts based on information such as the appearance and dimensions of existing parts. The drawing method in traditional CAD software is to first measure the dimensions of the assembly area and calculate the shapes, and then draw the parts. While this approach is feasible, errors are likely to occur during the repeated drawing and measurement processes, reducing work efficiency. However, the “in-place creation” feature of HaoChen 3D drawing software offers you a different experience! Haocheng 3D drawing software utilizes next-generation intelligent parameter modeling technology; it is a comprehensive efficiency tool that offers true 3D model design, advanced sheet metal design, as well as complete 2D+3D integrated design, spanning the entire process from conceptual design to product manufacturing. The HaoChen 3D drawing software not only supports the data formats of mainstream 3D design software, but also enables efficient reuse of design models through precise management of model data. The “Create in Place” function of the HaoChen 3D drawing software allows, within the current assembly mode, to create a new part using a Top-Down design approach, based on data such as the edges, positions, and dimensions of other parts in the assembly. This enables efficient reuse of model data, reduces the amount of repetitive work for CAD engineers, improves work efficiency, and lowers the likelihood of errors. Compared to traditional 3D software, HaoChen 3D drawing software offers greater advantages in terms of \"in-place creation\"! Advantages of HaoChen 3D software’s “in-situ creation”: l Create parts directly on the assembly; l Use the features of the assembly as a reference for design; l It is possible to draw parts using the features of the assembly. So how does one carry out “in-situ creation”? The specific steps are as follows. Step 1: Bring up the in-place creation command. Open the HaoChen 3D Drawing software and select the assembly design environment. On the home tab, select the in-place creation option or perform text search using the command search box. Step 2: Set basic option information. Click \"Create in place\" to bring up the settings for creating in place; you can adjust options such as the save location, coordinate placement, and editing mode according to your needs. Step 3: Settings and management of the toolbar. In the toolbar, select the type of part to create, such as assembly, welding, part, sheet metal, etc. At the same time, the toolbar can also manage material lists, assembly relationships, and types of position capture key points. Step 4: Create operation instances in-situ. In the assembly environment, parts that match the assembly model are created based on information such as its holes, shape, position, and usage requirements. Through this top-down design approach, it is not only possible to have a clear and comprehensive understanding of all component information during the drawing process, but it also saves design time and reduces human errors. 1. If an assembly is missing a sealing cover, it can be created in place based on the characteristic information of the top surface of the assembly. 2. If, in the frame design, a sheet metal panel is created to cover it. In conventional sheet metal design, inaccurate dimension measurements often lead to issues such as interference during assembly and shape inaccuracies, but these problems can be completely avoided by creating the design in situ. By capturing the positional information of the frame, and without the need to actually measure any dimensional data, sheet metal that matches the size and shape of the frame can be directly created in place. For more information on the applications and troubleshooting tips related to the \"in-place creation\" function of the HaoChen 3D drawing software, those who are interested can give it a try~
