3D Designing a Tringle Illusion in CAD Software
In this tutorial, we are going to 3D design a triangle optical illusion. The 3D modeling software that we are using is SelfCAD. With SelfCAD, you can easily make 3D models without contributing a huge load of energy learning, and you can make both essential and complex designs without taking a lot of time. The tools of SelfCAD that we will utilize are the 3D Sketch, polygon selection, Extrusion tool, Move tool, etc. We will begin by 3D designing a square and changing it. By figuring out how to 3D design this optical illusion, you will get to know how to use the various tools of SelfCAD.
So, let's start!
Step1: Create the initial process of the model
Today we will create a 3D triangle optical illusion. First, we will opt for the 3D sketch and choose the top view. We will choose the line sketch and draw a line of 135 mm horizontally and set the angle to 360 degrees.
Then we will move to the 3D top with a length of 150 mm and an angle of 90 degrees.
Step2: Make the 2D object for following the path
After that, we will create a new profile. We will select the rectangle that we developed recently. Then we will go to modify and add thickness. By doing so, we will provide mass to the selected profile. Set the thickness to 50. Next, make another square of 30mm length. Then select both the profiles and convert them into 3D by choosing follow path tool.
Set all the settings as shown in the image above. Then follow the path and make the profile. Then we will delete all the unwanted 2D profiles.
Step3: Fill the open spaces
Next, we will use the fill polygon to make the object a closed one. Then we will add a rectangular profile on the top corner of the object.
For that, we will opt for the 3D sketch. Select a rectangle and create it on the topmost corner. Then we will go to tools and select fill polygon.
Step4: Add thickness to the newly created rectangle
Now, we will select the add thickness which is found under modify. Set the thickness to 50.
Next, we will select polygon selection. Then select the top face. Now, go to modify and choose the extrusion tool. Set the amount to 55, and then it will get extruded.
Step5: Create an angular 3D sketch
Till now, we have created this simple 3D model. Next, we will be imposing angles in this model. For that, we will select the 3d sketch, and then we will choose the line tool. Then we will mark a point at the corner vertex and move it angular.
We will set the line’s length to 50mm and the angle to 230 degrees.
Now, continue the line along the edges and close it by taking it to the starting point. Then we will use the fill polygon tool again. Next, we will use the add thickness to convert it into a 3D model. Set the thickness to 50.
Step6: Add thickness to the face
Now, we will choose polygon selection. Now, select the top face and go to modify. Select the extrusion again and set the amount to 55.
Then unselect the polygon selection. Now, use the move tool and move it along the blue axis to the center point of the vertical structure.
Let us now select the vertical structure and the one we created recently. Go to stitch and scoop and choose the subtract option. Then again, delete the unwanted 2D profiles.
And we have just created a 3D triangle optical illusion!
We will see if we can move it slowly along a particular axis.
We also can select both the individual profiles and merge them. For that, go to utilities and select the merge option.
Conclusion:
We have successfully 3d designed the triangle optical illusion in SelfCAD. This tutorial deals with the fundamental tools of SelfCAD like edge selection and 3D shapes and uses other crucial tools like extrusion, move, and 3D Sketch. All the 3D models made in SelfCAD are 3D printable as they leave no numerical bungles that could make arrangements difficult to print.
Once wrapped up with the design cycle, you can use the in-collected slicer of SelfCAD to cut your design and produce the G-Code record that you can transport off your 3D printer. With everything considered, we trust you notice the tutorial article and observe the procedure as informative and supportive.
Enjoy powerful modeling, rendering, and 3D printing tools without the steep learning curve.
