However, there are aspects of the design process that are up to 100 times faster, if not more. In fact, if you start a design from scratch, the initial design process may only be slightly faster in the synchronous paradigm. It is not saying that all your designs can be done 100 times faster. “Synchronous technology provides the first history-free, feature-based modeling technology that enables up to 100 times faster design experience.” If you believe the marketing from Siemens, they claim the following: Pros and Cons of the Synchronous paradigm The next question then becomes how can synchronous eliminate or minimize the problems we face in ordered, and is it enough of an improvement to start using synchronous modeling? To answer this question, let’s look at the Pros and Cons of the synchronous paradigm. I’m sure my colleagues could list a few others, but I think these are the main ones. Working with foreign data can be a challenge without the history/feature tree.This makes opening and saving times lengthy. Models are heavy because of all the history saved in the part files.On large models, re-compute times can be lengthy due to the structured approach.In some situations, it has proven faster to re-model the part then to try and understand all the parent-child relationships. Making changes requires an in-depth understanding of how the model was originally created.Editing the model is slow and cumbersome if the designer incorrectly predicted future changes, or uses the part as a reference part to initiate a new model.Modeling requires the designer to predict how the model could change in the future.Forced structured approach to modeling.With that in mind, let me list some of the main problems with ordered designs: Many designers will disagree with some of these because they don’t have a true understanding of how synchronous modeling works. It should be noted that some of the Cons or disadvantages that I am about to list come from working with the synchronous technology for almost six years now. So what are the Cons of the ordered method? In other words, there were a lot of Cons in 2D design. Why? Because the industry recognized that switching to 3D design provided many advantages. But, we all know many companies have switched to 3D. It looks very similar to the list of reasons designers gave for staying in 2D. However, when I look at the list, I get a feeling of déjà vu. I am use to ordered design and have lots of ordered legacy data.įrom a designer’s point of view, all these are good reasons to stay in the ordered paradigm.Creating the initial model is just as fast in ordered as it is in synchronous method.Long accepted method of modeling with a proven track record.Easy to set up a family of parts or a family of assemblies with a master model approach.Other users can’t accidentally change my design.Ability to lock down how the model behaves.Predictability to the designer who created the model.This involves some thinking ahead and predictions of potential future edits. By doing this, he/she is controlling how the sketch can change. He/she draws the profile and constrains it with 2D geometric and dimensional constraints. Ordered modeling forces the user to build the model in a certain order of steps, which are predefined by the intent of the designer.įor example, the designer starts with the sketch or profile for his/her base feature. Many of the users I talk to claim that they like the control ordered modeling gives them. It’s like an old friend that many long time users are comfortable with and experienced in. Ordered modeling has been in Solid Edge since day one. To understand the benefits, we first have to look at the pros and cons of each paradigm. The true power behind Solid Edge is its hybrid approach that integrates both modeling methods. This may seem like a political answer, but it’s not. To which they smile and usually ask “No, really, which is better?” To which I respond, why choose? Use both. Many Solid Edge users ask me if they should be using the synchronous or ordered modeling method for their designs.
