Technical surfacing and analysis has become a whole lot easier with PTC Creo 3.0. The latest productivity enhancements enable you to quickly and easily investigate the challenging parts of your geometry. In today’s blog post we will discuss how to analyze the curves and surfaces in your model for position, tangency, and curvature continuity using the Connection Analysis feature. The Connection Analysis features shows where geometric connections are not met based on the desired input and tolerance. In this post, Paul Sagar, Vice President of Product Management, explains more here:
To begin, click on the Analysis tab, open the Inspect Geometry drop down menu, and select Connection to open the Connection Analysis dialogue box.
Use the Inspect Geometry drop down menu to select Connection.
The Connection Analysis dialogue box allows you to analyze the Position, Tangency, or Curvature connection between surfaces or curves. For example, if you select Tangency, you can perform a tangency analysis of the entire quilt. To do so, click on the model to select your References. Select Tangency as the Connection to be analyzed and enter the desired Tolerance in degrees. The edges of your model that do not meet the required tangency tolerance are displayed in red and the edges that conform to the tolerance are highlighted in green. If you prefer, you can display the results as spikes by changing the Style to Show spikes.
Notice how the areas that pass are shown in green and the areas that fail are shown in red.
To see only areas that fail against tangency and the respective notes, click the plus sign next to Display options. Check the box for Show only connections that fail. Only areas that fail will appear in red.
Notice that the areas of failure are highlighted in red.
To see only the areas that fail against Position or Curvature, switch your Connection selection, and enter the desired tolerance. You will see different areas of the model turn red as you toggle between the Connection options.
Here you can see the areas where the Curvature connections fail against a Tolerance of 5.0%.
To understand the value of the analysis at a particular location, check the box for Enable tooltips and place your pointer on the area where breaks exist. The value of the analysis will appear at that point.
Here you can see that the value of the curvature is 12.5122 in one area and 6.43476 in another.
