After a very long time I’m back again. So what we did last time was designed a chess bishop using OpenSCAD , and today we are going to design the same using FreeCAD (an open source and free CAD software).
It took me around 30-35 minutes to make the model.
Before getting started, just like before we will divide the bishop into basic solids.
This was the bishop that we made last time in OpenSCAD, the same we are going to do today but in FreeCAD.
Open FreeCAD and select part workbench as there we can easily and directly creat our basic solids shapes that are required for our chess bishop.
From “1. Basic shapes” as the image we can create different shapes like cube, sphere, cylinder, cone etc. From the “2. Basic settings” we can change the dimensions and position/placement of the solid.
Step 1: The sphere
Click on to the sphere icon to create the sphere, now change the radius of the sphere to 20 (going to keep the dimensions same as the bishop of OpenSCAD) we are going to keep this sphere at the center itself.
Step 2: The cone
Now click on to the cone to creat it. When you will do that you will see that no cone was created, but it is actually there. Because of its small dimensions it is hidden inside the sphere we made.
From the image you may see that “2” shows that a cone is present. “4” is the dimension of the cone, change it as we did in OpenSCAD. “5” is an area where the cone or I may say frustum is there but hidden inside the sphere.
After changing the dimensions accordingly we may see that the shape is not at all like a water-drop, so as we did last time we will place the bishop accordingly by clicking the placement.
After placing correctly the shape looks something what like the below image.
Step 3: Union of solids
Now it time to unite the two solids we created, the same thing we also did in OpenSCAD right.
In the image above from “1” we can perform ‘union’, ‘difference’ etc.
Clicking to that it will as you to select the two solids. Select them and click “Union” and then “Apply” and then “close”.
Step 4: Dollop/Joker nose
Now the procedure for other solids are also going to be same.
Going to the Dollop shape or we can say Jokers nose shape.
Create a sphere, change its dimensions and placement accordingly.
Then unite it with the water drop shape and we are done with the head part.
Neck And Base:
To create neck click on cone and change its radius1 and radius2 change it’s height to create a frustum and place it correctly.
Click on cone again change its radius1 and radius2 also it’s height and place it to the bottom and that will create the base.
Unite the neck and base.
Now it’s the turn for collar of the bishop.
Creating the collar is simple just we have to do is to create a cone change its radius1 and radius2 and place it little upper to its neck, now create another cone do the same and rotate it by 180°, and unite the two frustum.
After doing this unite “collar” and “neck-base”.
Also unite the head and lower part to create the “raw bishop”
The collar is also done. Now it’s time for the final step i.e. the cut out slot
Cut out slot:
To do that create a cube change its height and length accordingly and also it’s width. Place it accordingly and also rotate it 45°.
Which will look something what like the above image.
Now we have to cut the cuboid from the raw bishop that we had created.
For that the procedure is same as Union just we have to click the difference Boolean operation.
Which will look something what like this.
Now we are done with the bishop and it just took 30-35 minutes to make it. Isn’t it simple to make complex shapes using basic and simple shapes?
Our final Chess bishop will look like this
Hope you enjoyed it. 😉
