Creating 3D Design of Cookie Form using a 3D Modeling Software

 |  Devyani Nagare

Cookies, the delicious snack kids love so much. Actually, everyone loves eating cookies or biscuits. Cookies mostly come in a round shape but there are also other attractive shapes. A cookie requires a form to be made. The star-shaped cookie is attractive and also easy to make with the star found in 3D modeling software. The form is usually made up of copper, tin, stainless steel, aluminum, or plastic. To produce the shape, the cutter or form is pressed into cookie dough. 

In this tutorial, we are making a star-shaped cookie form in 3D modeling software. Creating this shape with a hollow section is easy with SelfCAD tools like Difference, Sitch & Scoop, Scale, etc. 

This tutorial will help you to learn more about the various techniques of 3D modeling software like scaling designs to make certain defined shapes and also hollowing sections. This is a step-by-step tutorial that will help you to understand the use of Basic 3D shapes

Step 1: Create Object

Here we are using a cylinder as a standard form and using a foundation to create the form. You can select the Cylinder from the basic shapes section or use the shortcut (P+Y). Set the Parameters as follows: Vertical Segment to 10, this is the basic dimension but we will edit it to achieve our desired shape. Finalize the Cylinder.

Step 2: Activate Polygon

Activate the Polygon Selection from the selection modes or use the shortcut (Ctrl+4). Click on the region to select it. We will be needing the polygons for the next step. Now Click on the Delete button or use the shortcut (Del).

This is the base shape of the form. Next Click on Activate Vertex Solution or use the shortcut (Ctrl+3). Vertex is known as the point where edges connect to create faces. 

Now will select the vertex points on the shape to make the star-shaped form.

Step 3: Activate Scale

Select the Scale Tool from the Toolbar or use a shortcut (S). Set the Parameter as follows: X to 40, Z to 40, and keep others as they are. Close the Transformation Panel.

We made the star using scale. 

Step 4: Activate Object Selection

Click on the region of the Selection cube, or use the shortcut (Ctrl+0) to deselect the region.

We will modify the form. 

Next, go to Modify Category on the toolbar and select Add Thickness Tool or use the shortcut (M+A). Set the Thickness to 1 and set Mirror thickness to True. This will give thickness to the form. Finalize the Thickness. We always need to finalize until we finish the changes to most of the geometry.

Step 5: Activate Polygon

Click to activate the Polygon Selection or use the shortcut (Ctrl+4). With this, we will add border thickness. Click on the region to select it.

Next, go to Modify Category on the toolbar and select Inset or use the shortcut (M+I). This will help us to properly shape the form. Set the Inset to 3. 

Click on Add Option. You can find it in the Advanced Setting for the next Macro Setting. With this, we will add more modifications.

Next set parameters:

Set the operation to Extrusion Tool: Set amount 10. So here we are making the handle using extrusion.

Click on Add Option. You can find it in the Advanced Setting for the next Macro Setting. Set the operation to Inset: Set amount 1. Finalize the Inset.

Step 6: Copy the Object and add thickness

Now click on Copy or use the shortcut (Ctrl+C). Next, go to Modify Category on the toolbar and select Add Thickness Tool or use the shortcut (M+A). Set the Thickness to 12, and set mirrored thickness to True. Finalize the Thickness.

Step 7: Activate Stitch & Scoop

Click on the region of the Selection cube, or use the shortcut (Ctrl+0) to deselect the region. Now click on mesh_4 to select it, next, activate the Stitch & Scoop tool from the Toolbar or use the shortcut (B). Those are the Boolean operations that will help us to create the proper form. 

From the tool panel, choose Difference or use the shortcut (B+D). Next, Select mesh_4(1) in Object to Subtract. This will make the form Hollow. 

Finalize the Difference.

 Conclusion:

Creating 3D shape forms using 3D modeling software is something new, and learning how to 3D design them will help you learn more about both basic shapes and tools of 3D modeling software like SelfCAD. 

When you have finished with the 3D design process, you can choose to print if you own a 3D printer, or you can outsource it. Your design is not printable as it is. You need to convert it to a format that can be understood by a 3D printer. To do this, you can select the 3D Print tool, and it will direct you to the slicer, which you can use to generate the G-Code that contains the instructions on how the design will be printed.


Enjoy powerful modeling, rendering, and 3D printing features without the steep learning curve.
