How to convert a CAD three-dimensional drawing into a plane drawing?

1. First, open the 3D drawing dwg file in the drawing.

2. Choose File-New. Create a new dwg drawing file.

3. At this time, enter "flat shot"-"space" at the command line.

4. The "Plane Photography" dialog box pops up, and select "Insert as New Block". The "hidden line" refers to the hidden line of the three-dimensional diagram. If it is necessary to show hidden lines, you can check them.

5. After setting, select the "Overlooking" view in the "View" tab.

6. The line width of the converted floor plan is 0mm, which will not be clear if it is directly used for printing.

7. Set the line width with the layer "ByLayer".

8. In this way, a three-dimensional entity is transformed into a two-dimensional plan in Cad.
