Simply click the 3D sketch button on the weldments tab to begin creating a 3D sketch. After selecting the button, pick the line command and select a starting point in the drawing area; no starting plane is required. The letters XY, YZ, or XZ will appear next to the cursor.
In programmes like SOLIDWORKS Weldments, you may use 3D sketches to insert structural elements along a 3D frame, create routing patterns, and reverse engineer meshes into solid parts. Click 3D Sketch (Sketch toolbar) or Insert > 3DSketch to make a 3D sketch.
The sketch serves as the foundation for a three-dimensional model. Any of the default planes (Front Plane, Top Plane, and Right Plane) or a generated plane can be used to produce a sketch. Choose from the following options to get started: Sketch entity tools (line, circle, and so on) Tool for drawing.
