ZW3D is a CAD/CAM solution designed for beginners and professionals. With its intuitive interface and clear feature-based workflow, ZW3D helps users quickly understand the modeling process and start creating 3D designs.
Whether you are new to ZW3D or looking to get familiar with its core tools and workflows, this starter guide will walk you through the basic interface, essential modeling tools, and common workflows step by step.
By following this guide, beginners can quickly build a foundation in ZW3D and start creating their first 3D models with confidence.
After downloading and opening ZW3D, you will see the following interface:
The image below shows the ZW3D operation screen. There are ribbon tabs that allow you to switch between menus, and on the left side of the screen, your work history is saved and can be managed and modified.
Key areas include:
This structured layout helps users quickly locate tools, manage design data, and improve overall efficiency. For a more detailed breakdown of each interface component, see the full guide: ZW3D User Interface Guide
While viewpoint control is done using the mouse, you can zoom in and out by rolling the mouse wheel. You can move the viewpoint by pressing and holding the mouse wheel without rolling it and moving the mouse. You can rotate the viewpoint by pressing and holding the right mouse button and moving the mouse. In other 3D CAD programs, you may have to press the Shift or Alt key with the hand opposite to the one holding the mouse, but ZW3D allows you to control the viewpoint with just one hand using the mouse, which is very convenient.
Other than that, mouse operation is the same as usual. You can display a pop-up menu with the right mouse button, and select menus and icons with the left mouse button. A distinctive feature is that you can confirm input by pressing the mouse wheel (middle button), and you can also recall the command that was executed just before. This is a very convenient feature that can save you time while working.
Please note the difference between "Clicking" the middle button (to Confirm) and "Holding & Dragging" it (to Pan). Avoid clicking it accidentally while moving your view, as it may unexpectedly confirm or end your current command.
After launching ZW3D, it is recommended that first-time users start with the built-in Show-n-Tell tutorial. This interactive tutorial guides you through the basic operations step by step. By following the on-screen instructions, you can quickly understand core workflows such as navigation, selection, and basic modeling.
Click Show-n-Tell > Introduction.
This feature allows you to learn how to operate the system while following the on-screen instructions. Through a series of simple steps, you can gain an initial understanding of ZW3D’s basic functions through hands-on practice. The tutorial includes helpful notes, detailed operating instructions, and illustrative images, and the entire process takes only 10–20 minutes to complete.
To begin creating data, click New, then select the type and template. For example, if you want to perform regular modeling, select Part for the object type, Standard for the subtype, and Default for the template. Then, enter the object name (file name) and click OK.
Generally, 3D models are created by first creating a 2D outline (profile) using the sketching function, and then converting it into a 3D object (three-dimensional object) by extruding, rotating, etc., using the features function.
A feature is a function or command used to create a 3D model, and it also refers to the shape that is created by that function. It is also called a shape processing element, and it is easiest to understand if you think of "feature = operation".
This section demonstrates how to create a 3D model in ZW3D.
Select Sketch in the Shape tab, choose the plane on which to draw the sketch, choose the orientation and click the green checkmark button to confirm. (You can also confirm by pressing the middle mouse button.)
The menu will automatically switch to Sketch. Here, we will use the Rectangle command to draw one with a width of 200mm and a height of 100mm, centered at the origin.
If you want to change the values, double-click them.
In ZW3D, the line color changes from black to blue when the size and position of the drawn sketch are fully defined, meaning that all required dimensions and relationships have been specified. This helps you visually check whether any constraints are missing.
Tips:
Always ensure your sketch turns completely blue before exiting. Leaving lines black (under-defined) can cause your 3D model to unexpectedly distort or break when making future design changes.
Once you have finished drawing the required sketch, click Exit. After the sketch is completed, the defined dimensions (such as distances) will be hidden. If you want to edit the sketch again, simply double-click the corresponding sketch in the History Manager on the left side of the screen.
Create a block with a thickness of 50 mm. Select Extrude in the Basic Shape tab, select the sketch you drew as the profile, set the Start Type to Value, set the End E value to 50 mm, and confirm with the OK button.
We will now create round holes in the block we have created. Select Sketch and choose the top surface of the block as the plane on which to draw the sketch. You can also draw sketches on any other flat surface of the 3D object you have created.
Use the Circle command to draw a circle with a diameter of 30 mm on the X-axis.
The sketch lines are black, indicating that the sketch is not fully defined. Use Quick Dimension to set the distance from the left edge of the block to the center of the circle to 40 mm. This defines the horizontal distance. Since the vertical axis coincides with the X-axis, the sketch becomes fully defined, and the circle changes to blue. Now we can exit the sketch.
Select Extrude from the Basic Shape tab and choose the circle sketch you drew as the profile. If the extrusion direction points outward, click the Reverse button to change the direction. Set End Type to Through All, and set Boolean to Remove. Then click OK to confirm.
Next, we will chamfer and fillet the corners of the block.
First, click Chamfer. Then select the two corner edges of the block. Set the chamfer value to 20 mm, and click OK to confirm.
Second, select Fillet, select the two edges on the opposite corner, set the value to 40 mm, and confirm with the OK button.
The history of your work up to this point is saved on the left side of the screen. The tasks you have performed are listed from top to bottom, and you can re-edit each task by double-clicking it, allowing you to resize and modify its shape. You can also right-click each task to delete it or blank/unhide (show/remove) it.
You can open the History Manager to view the steps of your modeling process (as shown in the figure). The history of your work is displayed in the panel on the left side of the screen. The operations you have performed are listed from top to bottom. You can re-edit any operation by double-clicking it, which allows you to adjust its size or modify its shape. You can also right-click an operation to delete it or to blank/unblank (hide/show) it.
3D features are built hierarchically. If you Delete a foundational parent feature (like Extrude_1), all subsequent child features that rely on it (such as your holes or fillets) will break and show errors. If you just want to temporarily clean up your screen, always use the Blank (Hide) option instead of deleting.
So far, we have introduced how to get started with ZW3D and covered some basic usage instructions. I have only demonstrated basic functions such as sketching, extrusion, chamfering, and filleting, but by combining these functions, you can create many other parts. To gain a better command of ZW3D, I encourage you to practice the functions introduced here repeatedly until you become proficient.
We will continue to introduce more detailed usage instructions in the future. For those who want to learn more in the meantime, please refer to the training manuals in the Help section.
