Components

Indicators

These components can be used in assemblies during development as a means to debug your part placement, and to demonstrate Mate coordinate systems.

• Coordinate System Indicator

• Planar Indicator

Examples

Use indicator on a primative

To illustrate how an inciator can be used to show where a Mate is on a Part, we’ll create a simple Assembly:

import cqparts
from cqparts.constraint import Fixed, Coincident

from cqparts_misc.basic.indicators import CoordSysIndicator
from cqparts_misc.basic.primatives import Box


class MyAsm(cqparts.Assembly):
    def make_components(self):
        return {
            'box': Box(length=30, width=20, height=10),
            'indicator': CoordSysIndicator(),
        }

    def make_constraints(self):
        return [
            Fixed(self.components['box'].mate_origin),  # fix at world origin
            Coincident(
                self.components['indicator'].mate_origin,
                self.components['box'].mate_neg_y,
            ),
        ]


from cqparts.display import display
display(MyAsm())

From this we can see that the mate_neg_y mate has:

• its Z-axis along the world -Y-axis, and

• its X-axis along the world Z-axis.
