In real life when we see some objects they are usually made in pairs. These pairs are geometrically similar but identical. For example, if we see pair of shoes. The geometrical shape of the shoes is the same but we cannot wear the left shoe on the right foot or vice versa. To create such designs or models we have to create some relations or make the design again from scratch. We have to make the changes according to the need.
Solidworks has a few features using which we can create derived objects. Derived means Obtaining something from or from a specific source. What happened in the derived part is the sketch parameters and dimensions are the same only the orientation is changed.
Creating Derived part from Mirror Feature
Using the mirror feature we can create a replica of the part or components. We just have to define the face or plane at some distance and mirror the part. This is one way to create the derived parts.
To create the derived part from the mirror feature command first open the part. You can use this option while designing parts as well. Go to Features Tab and Click on Mirror.
The next step is to select the plane or the face about which you are going to derive the part. Select the Plane under PropertyManager and Bodies to Mirror select the part. You can select the part directly from the graphics area or design tree. After selecting the part you see the graphical representation of the part, and how it’s going to create after using the command. To see this preview you must check on ‘Partial preview‘ or ‘Full preview‘ under Option.
After selecting the plane and part Click on OK. The derived part will be created.
There is one more setting option under ‘Option‘ which is merge solids. This option can be used in different conditions. Like if you want the derived part to be linked with the original part as a single body you can check this. If you want the derived part to be a separate body then you should uncheck this merge bodies option.
Creating Derived part using Pattern Command
In pattern command, we see options like
- Linear pattern
- Circular pattern
- Mirror pattern
- Curve, Sketch, and Table driven pattern
- Fill pattern
- Variable pattern
In this part of the article, we are going to look at how to create a driven part using a circular pattern. You can use another pattern command whenever and where needed. We have already discussed how to use the Mirror feature.
Creating derived part using a circular pattern
From creating a circular pattern you should have an axis, circular sketch, or profile about which the part will be created.
Go to the Features tab, then Click on the linear Pattern dropdown, and under that click on Circular pattern.
Now select the axis of rotation, give the number of entities we have to create and the angle between those entities, and under Bodies select the part. Then Click on OK.
