Top-down and bottom-up approach in assembly modeling
what is the difference between top down and bottom up approach?GNANAVEL K 26 Jul, 2017 12:14 PM top down and bottom up approach? 3 Answersdhananjay rehere Answered on 26 Jul, 2017 12:58 PM Bottom-up If you dont know what you are doing, dont plan yourself ahead of time or/and if you work alone: Example 01: Create this support without knowing exactly where it will be fixed. After you finish you part desing, you will start to be concerned about creating the supoort that is missing. Top-down If you know what you are doing, if you plan yourself ahead of time and/or if you work with a group: Example 02: Create this mechanism using a skeleton/layout. Just remember that you can use a lot of different things as a contextual reference (planes, surfaces, notes). FredSWUG Answered on 26 Jul, 2017 01:02 PM Top down: Bottom up. Both methods have pros and cons in different situations. Asim Rashid Answered on 20 Feb, 2018 12:47 PM A top-down design project starts with the broad project specification in mind and putting that information in a centralized location. The design process progresses by communicating the centralized information to the individual parts. In bottom-up approach, the individual parts are designed to fulfil the intended function and then put together to form assemblies of a product. After the assembly is in place, problems are identified and modifications to individual components are made. As components are independent of each other, if one component is modified, the related components have to be changed manually. You can have a look at the following blog post for detail description. http://caeuniversity.com/2015/03/16/bottom-up-and-top-down-approach/ what is the difference between top down and bottom up approach?GNANAVEL K 26 Jul, 2017 12:14 PM top down and bottom up approach? 3 Answersdhananjay rehere Answered on 26 Jul, 2017 12:58 PM Bottom-up If you dont know what you are doing, dont plan yourself ahead of time or/and if you work alone: Example 01: Create this support without knowing exactly where it will be fixed.
