Tiếng ViệtA: Yes, it is possible convert 2D polyline into a 3D polyline in BricsCAD?
There are three types of polylines in DWG geometry: Lightweight 2D Polyline, Heavyweight 2D Polyline, and 3D Polyline.
For most 2D drawings, Lightweight 2D Polylines are commonly used due to their data efficiency. However, there are cases where a polyline representing a three-dimensional path needs to be converted into a 3D Polyline.
In BricsCAD, there is a command called the Polyline Conversion Command (_CONVERTPOLY) that allows for converting one type of polyline into another, including the conversion to 3D polylines.
Polyline Conversion Command (_CONVERTPOLY)
This command isn’t placed in the ribbon menu, so it must be executed by typing the command name “CONVERTPOLY” directly into the command line.
When executed, the system prompts you to select the type of polyline to which you’d like to convert. You can choose the desired option either by clicking with the mouse or entering the corresponding keyword.
One of the options available is to convert to a 3D Polyline.
After specifying the desired conversion option, you simply select the polyline geometry you wish to convert. Any elements that cannot be converted will be excluded from the selection.
Converting a 3D Polyline to a 2D Polyline
Conversely, when converting a 3D Polyline back into a 2D Polyline, the system converts the 3D coordinates into their 2D equivalents. During this process, you can specify whether you want to preserve the original shape as much as possible.
Selecting “Yes” will result in a polyline divided into segments that can be handled as a 2D plane.
If you prefer to prioritize flattening the geometry, the polyline will be converted into individual line segments, but you can use the Flatten Command (_FLATTEN) to simplify the shape into a purely 2D form.
