- Create a sketch
- Close the sketch
- Linear pattern
- Polar pattern
- Multitransform (mirror, linear/polar pattern combined)
New functions - basicsCreate an rectangle (sketch) on the XY plane. The rectangle should be symmetrical to X and Y axes (simply select two corners and an axis then click symmetrical constraint button).
Pad the sketch. Please notice new available options: type (Dimension, To last, To first, Up to face, Two dimensions) symmetrical (yes/no), reversed (yes/no).
Select side face on the pad, and sketch a rectangle. It will be used for a groove feature. The groove is similar to pocket but material is removed around axis (like in a revolution).
Select the sketch and click Groove a selected sketch. Adjust angle and side in the Tasks tab. Note: sketches for almost all features (except pads) need a support face. The face should be selected before you start sketching - in other case use Map sketch to face from Part Design menu.
In next steps you will create a mirrored feature. Select the top face and sketch a circle.
Pocket the circle, set pocket type to Through all.
Select the pocket and use Create a mirrored feature. Set plane to XZ. Note: mirror of multiple holes can be unsupported in actual version of FreeCAD (implementation needed).
Linear pattern is an another useful function. Create a pad on side face, parallel to XZ plane.
Select the pad and use Create a linear pattern feature. Set direction to X, adjust length (should be lower than the body length) and occurrences number.
The most advances is a multitransform feature. You can mix linear and polar patterns and mirrored or scaled features. Select top face.
Sketch a circle close to (0,0) point.
Pad the circle.
Use Create a multitransform feature. Right click in the Transformations text area and then Add linear pattern.
Set occurrences to 2 and direction to X.
Then you can Add polar pattern in similar way. The direction is Z and occurrences is 5 (experiment with them!).
I want add XY mirror but in this case body must be symmetrical to XY. Edit the first pad - set Type to Symmetric to plane.
Now you can finish edit the multitransform feature. Use right click to Add mirrored transformation. Set plane to XY.
The final effect:
