Use of Constraints in IRONCAD

IRONCAD is built on the principle of not having to use constraints (locks/relationships) between parts in space. So it is not a requirement, but there is a possibility, to use these constraints which in most other 3D CAD systems is a direct requirement.

Simply explained, it is a way of placing one's parts in space in relation (constrained with) other parts. These constraints can accurately visualize how your parts and assemblies would work with each other in the real world. Lock some of the parts together with constraints and select the mechanism mode tool (Mechanism Mode), which gives you the ability to move the parts/assemblies by dragging them with your mouse or TriBall and works with positioning constraints to ensure your design has the correct tolerances and fit.

However, it should be borne in mind that every constraint added whill in turn severely limits features such as TriBall, handles, etc. The constraint approach is usually referred to as one's Design Intent ("how do I want this to work") and is very good in fully predictable designs, but often very counterproductive in the early design phase and when unexpected changes are needed.

How to use Mate and Concentric

TheMate and Align tools are used to match surfaces to each other in different ways. Either along or against a surface.

‍

How to use Coincident and Align

The Coincident andConcentric constraints use circular surfaces to ensure that they are always in contact with each other.

‍

How to use Parallel and Perpendicular

TheParallel andPerpendicular tools are used to ensure that the edges of a part can be either parallel or perpendicular to the edges of another part.

‍

How to use Tangent

Tangent creates a constraint that ensures that the round surface is always tangent to the other selected surface, which can be flat or round.

‍

How to use Distance

Distance creates a constraint that keeps one part/assembly a certain distance from the other selected part.

‍

How to use Angle

The Angle command ensures that an angle is maintained.

‍

How to use Follower/CAM

Follower/CAM is used when the constraint should follow a surface like a camshaft.

‍

How to use Pin/Slot

Pin/Slot follows the path of the track while allowing the pin to rotate freely.
