Disclosed is a parametric feature-based 3D CAD system that allows multiple users to simultaneously edit a parametric feature-based 3D CAD model consisting of 3D parts and assemblies of those parts (3D Model). Several CAD users, each using their own computer, phone, or tablet, can edit the same 3D Model at the same time. Editing may be separate and simultaneous&#x2014;there is no need for users to worry about locking, checking out, or otherwise restricting each other's access to 3D Models. As a result, users see each other's changes occur in real-time, and may also identify what aspects other users are actively modifying through visible Collaboration Cues.

The disclosed non-linear slider control enables a single control to rapidly change orders of magnitude in the scale of control by varying the bounds and quantization interval based on the value before the user begins a slide operation. The bigger the value is at the start, the larger the bounds and the interval. At the end of at least one slide control operation, the bounds and step interval value are recomputed.

Describe is a method for visually presenting, or previewing, changes to 3-dimensional geometry. In Onshape, a user may apply a sequence of configurable geometric operations in order to design a 3-dimensional model. When a user edits a specific operation, the method provides a way for the user to see the effects changes will have on a model. The method provides high-fidelity visualizations of the user's design as it would be before the operation is applied, after the operation is applied, and the operation's effects in conjunction with the effects of all operations in the sequence. The method also provides an interface for transitioning between these visualized states, allowing the user to effectively and efficiently understand the effect of the changes.

Previewing changes on a geometric design

The disclosed non-linear slider control enables a single control to rapidly change orders of magnitude in the scale of control by varying the bounds and quantization interval based on the value before the user begins a slide operation. The bigger the value is at the start, the larger the bounds and the interval. At the end of the slide operation, the bounds and step interval value are recomputed such that the end of the slider operation is centered in the new bounds.

A method of propagating changes in a design model identifies a change to a changed element, creates steps to carry out the change, creates additional steps based on the change and on relationships between the changed element and other elements in the design model, and executes the steps to alter the model in a manner that reflects the change. The steps may be created in a manner that depends on other steps that have been created. A system for regenerating a design model comprises a model element, a step propagator, and a step executor. The step propagator receives a first step that represents changes in the model element, and produces a second step that represents other changes in the model element that are dependent on the first step, and the step executor executes the first and second steps.
