Understanding the Cut Tool
The Cut Tool in Selfcad is a versatile tool that allows you to modify the geometry of your models. Here’s a detailed explanation of its key features and functionalities.
The Cut Tool is located in the “Transform” tab of the toolbar. It operates on the principle of Boolean operations, where it divides a target object by splitting it into two or more separate parts. The target object can be any 3D model or shape within the scene.
To use the Cut Tool, you can either select the target object directly or utilize the marquee selection tool to encompass multiple objects. Once selected, the Cut Tool requires two additional inputs: the cutting tool and the cutting shape. The cutting tool can be either a plane, a box, or a cylinder, each with its own unique cutting behavior. The cutting shape defines the silhouette or contour that you wish to cut out of the target object.
The Cut Tool can be employed for a variety of purposes, including sectioning models to inspect their internal structure, dividing objects into smaller, manageable components, or creating intricate designs and patterns. Its intuitive interface and precise control make it an essential tool for both beginners and advanced modelers alike.
| Cutting Tool | Behavior |
|---|---|
| Plane | Cuts along a flat plane, creating a sharp, straight edge |
| Box | Cuts along the faces of a box, yielding clean, perpendicular cuts |
| Cylinder | Cuts along the curved surface of a cylinder, resulting in smooth, cylindrical cuts |
Selecting Shapes for Cutting
To initiate the cutting process, you must first select the shapes that will be dissected. This selection can be made in various ways, depending on your specific requirements.
Using the Selection Tool
The Selection Tool is a versatile tool that allows you to select individual shapes or groups of shapes. To use this tool, simply click on the shapes you wish to select. You can also drag a selection box around the desired shapes to select them all simultaneously.
Using the Group Selection Tool
The Group Selection Tool is designed to select multiple shapes that are grouped together. To use this tool, click on the group of shapes that you wish to select. This will select all of the shapes within that group.
Selection Precision Options
Selfcad offers several precision options to refine your shape selection process:
| Option | Description |
|---|---|
| Whole Shape | Selects the entire shape as a single unit. |
| Nodes | Selects individual nodes or vertices within the shape. |
| Segments | Selects specific segments or edges within the shape. |
Creating a Cutting Path
Indicate the shape you want to cut using the vertex snap tool. Click on the first point of the cutting line, then click on the second point. Continue adding points to define the path. Alternatively, you can create a closed cutting path by double-clicking the first point after creating the desired path.
Tips for Creating a Precise Cutting Path
• Zoom in on the area you’re cutting to ensure precision.
• Use the grid to align your points and keep your lines straight.
• If you make a mistake, hit the “Esc” key to undo your last action.
• To delete a point, click on it and press “Del.”
• To adjust the curve of a line, drag the control point next to the desired point.
Once you have created a cutting path, you can use the “Cut Along Path” tool to cut the shape into multiple pieces. The cutting tool will automatically generate the necessary cuts and separate the pieces.
Cutting on Specific Paths
SelfCAD’s powerful cutting tools allow you to make precise cuts along specific paths. This feature enables you to create complex designs and shapes with ease.
To cut along a specific path:
- Create or import your path: Draw a path using the "Create" > "Sketch" tool or import an SVG file.
- Select the object and path: Select the object you want to cut and then the path along which you want to cut.
- Position the object: Adjust the position of the object so that it aligns with the path.
- Choose the "Cut" operation: From the "Modify" menu, select "Cut." In the "Cut" dialog box, ensure that the "Path" option is selected and then click "Cut."
Customizing the Cut
The “Cut” dialog box provides several options to customize your cut:
| Option | Description |
|---|---|
| Offset | Adjusts the distance between the cut line and the path. A positive value moves the cut line outward, while a negative value moves it inward. |
| Join Type | Specifies how the cut lines will connect at the corners. Options include “Miter,” “Bevel,” and “Round.” |
| End Type | Determines how the cut lines will end at the endpoints of the path. Options include “Butt,” “Round,” and “Square.” |
Experiment with these settings to achieve the desired cutting results. SelfCAD’s intuitive interface makes it easy to adjust and fine-tune your cuts until you’re satisfied with the outcome.
Cutting Multiple Shapes Simultaneously
To cut multiple shapes simultaneously, first select all the shapes you want to cut by holding down the Shift key while clicking on each shape. Then, right-click and select “Cut” from the menu. Alternatively, you can press the “Ctrl” key + “X” shortcut to cut the selected shapes.
Additional Details for Cutting Multiple Shapes Simultaneously
1. Cutting Shapes with Different Properties
You can cut shapes with different properties, such as colors, fills, and strokes. However, the cut operation will apply the properties of the primary shape to the newly pasted shape.
2. Cutting Shapes in Different Layers
If your shapes are in different layers, you can still cut them simultaneously. However, the cut shapes will be pasted into the same layer as the first selected shape.
Here is a table summarizing the behavior when cutting multiple shapes simultaneously:
|
Property |
Behavior |
|---|---|
|
Color and Fill |
Takes on the properties of the primary selected shape. |
|
Stroke |
Takes on the properties of the primary selected shape. |
|
Layer |
Pasted into the same layer as the primary selected shape. |
Adjusting Cutting Parameters
Fine-tuning the cutting parameters is crucial to achieve precise and satisfactory results. In SelfCAD, you have access to various settings that allow you to customize the cutting process according to your specific needs:
Offset
The offset parameter specifies the distance between the cutting edge and the original shape. A positive offset shifts the cut outward, while a negative offset shifts it inward. This setting is useful for adjusting the fit of the cut shape within the material or for creating relief effects.
Cut Depth
Cut depth determines how deep the tool will penetrate into the material. Proper cut depth is crucial for ensuring complete cuts without damaging the underlying surface. The optimal cut depth varies depending on the material thickness and type.
Feed Rate
Feed rate controls the speed at which the cutting tool moves through the material. A higher feed rate results in faster cuts, but it can also affect the quality of the cut. Too high a feed rate can lead to rough edges or tearing, while too low a feed rate can result in slow and inefficient cutting.
Spindle Speed
Spindle speed refers to the rotational velocity of the cutting tool. It is usually measured in revolutions per minute (RPM). Selecting the appropriate spindle speed is essential for optimizing cutting efficiency and reducing wear on the tool. Different materials require different spindle speeds.
Tool Compensation
Tool compensation accounts for the diameter of the cutting tool. This parameter ensures that the cutting tool follows the intended path precisely, even when using different tool diameters. It is especially important for achieving accurate and consistent cuts when using multiple tools.
Cut Order
Cut order determines the sequence in which the individual segments of the shape are cut. This parameter allows you to optimize the cutting process by minimizing tool travel time and reducing the risk of collisions.
| Parameter | Description |
|---|---|
| Offset | Distance between cutting edge and original shape |
| Cut Depth | Depth of tool penetration into material |
| Feed Rate | Speed of tool movement through material |
| Spindle Speed | Rotational velocity of cutting tool (RPM) |
| Tool Compensation | Accounts for cutting tool diameter |
| Cut Order | Sequence of shape segment cutting |
Smoothing Cut Edges
After cutting a shape into pieces, you may notice that the edges of the new pieces are jagged or rough. This can be smoothed out by using the Smooth command. To do this, select the edges you want to smooth and then go to the Edit menu > Smooth. You can also use the keyboard shortcut Ctrl + E (Windows) or Cmd + E (Mac) to smooth the edges.
The Smooth command has a number of options that you can use to control how the edges are smoothed. These options are available in the Smooth dialog box, which you can access by clicking on the Options button in the Smooth command.
The following table describes the options available in the Smooth dialog box:
| Option | Description |
|---|---|
| Amount | This option controls how much the edges are smoothed. A higher value will produce smoother edges, but it may also make the object appear less sharp. |
| Preserve Corners | This option controls whether or not the corners of the object are preserved when the edges are smoothed. If this option is enabled, the corners will retain their original sharpness. |
| Preserve Edge Shape | This option controls whether or not the shape of the edges is preserved when the edges are smoothed. If this option is enabled, the edges will retain their original shape. |
Merging Cut Fragments
Once you’ve cut your shape into pieces, you can merge them back together to create a new, single shape. Here’s how:
-
Select the fragments you want to merge.
-
Click “Edit” > “Merge.”
-
The fragments will be merged together into a single shape.
You can also merge cut fragments using the Boolean operations:
-
Union: Merges all selected fragments into a single shape.
-
Intersect: Creates a new shape that is the intersection of all selected fragments.
-
Subtract: Subtracts the selected fragments from the main shape.
To perform a Boolean operation:
-
Select the fragments you want to merge.
-
Click the “Boolean” dropdown menu in the toolbar.
-
Select the desired operation from the menu.
-
The selected fragments will be merged or subtracted according to the selected operation.
| Operation | Description |
|---|---|
| Union | Merges all selected fragments into a single shape. |
| Intersect | Creates a new shape that is the intersection of all selected fragments. |
| Subtract | Subtracts the selected fragments from the main shape. |
