## ZWCAD 2023: Edit a 3D Entity Using Grips

If you are a designer looking for a quick way to build simple parts like nuts, and modify them in a 2D CAD program, you must try our ZWCAD 2023.

In this version, with some existing commands, like Box, you can create a solid right away. You can also use the command “Extrude” to create a solid from a surface. After generating a solid, with the newly added method for 3D solid editing, you can easily change its shape and size and preview it at the same time.

Figure 1. Modify a solid with a triangle grip.

Triangle and rectangle grips make it flexible to modify a solid. They will appear when you select the solid. You can hold a grip and move it along the X/Y/Z axis to reshape the selected solid along a specific direction. The other way to resize an existing solid is to modify its 3D geometric values on the properties panel. The properties panel will pop up when you select the solid and those 3D geometric values can be found in the geometry part of the panel.

Let’s take a hexagon nut as an example. Here we have a prototype of a M3 hexagon nut. According to the standard, it should be 2.4 mm in height with a tolerance of 0.2 mm. But now the height of this prototype is only 2 mm, which doesn’t meet the standard.

To get its height right, you can input the correct value in the text field named “Height” on the properties panel. You can also keep Dynamic Input enabled, then drag the triangle grip to stretch the upper face of the nut along the Z axis and input the correct value.

Now we have a M3 hexagon nut ready for manufacturing. Additionally, there are many other new functions in the 3D editing part to discover!
