Enroute to ST4 – How the Synchronous Technology is different (part 3/5)

Concept number 4

Add and specify dimensional constraints in real time

How to reduce the pre-planning stage of a design? By using PMI dimensions on the 3D model.

With the concept number 3, we realized that Solid Edge is working to maintain the mechanical integrity of your model.

Here we begin to enter in a world where a large number of designers are not really aware or be familiar with the concept of dimensional constraints and this is part of the Solid Edge experience that cannot be quantified.

In a traditional linear model, adding dimensions must be done gradually as the model is built, meaning incrementally. It is very difficult to get an overall view of the dimensional constraints in your model.

One of the methods used to simulate a global work environment for the dimensional constraints is the skeletal modeling. This consists in placing the largest number of possible geometries and dimensions in one sketch, to centralize the edition of dimensional constraints. This approach is often the source of many problems inherent to this technique.

Very early in the development of Solid Edge two concepts have been introduced to help minimize, maybe eliminate errors related to skeletal approach:

  • The concept of dynamic editing.
  • The concept of Feature base modeling

The two combined allow us to have a better overview of our model. However it lacked a little something.

What if your 3D model was your skeleton?Synchronous Technology enables:

  • To add dimensions directly on the 3D, whenever and wherever necessary.
  • Reposition the dimensions as needed simply by dragging the handles.
  • Create master and reference dimensions
  • Create equations to parameterize your model

Solid Edge Synchronous Technology allows you to work the dimensions of your model in an absolute concept (global).

Next stop concept number 5

Part 1/5 – Features are using the concept of collection instead of the linear tree.

Eliminate the parent relationship between the features

Part 2/5 – Keep the mechanical integrity of the model

Part 4/5 – Edit non-linear model using parameters
