DuPont Engineering Polymers employs ANSYS and Moldflow. For these tools to be effective, fully defined 3D CAD models are needed. Until recently this has been a problem.
Limited Success
With few options DuPont turned to IGES -- typically requiring significant rework of data to isolate and correct errors. Because of the range of possible sources of native data --- each with its own standards for tolerances --- it was rare for a model to come in correct first time, and not uncommon for it to fail altogether.
Slashing Rework
CADfix detects imperfections in solid models and corrects them (automatically or interactively). The result is a fully formed, closed solid model that can be freely used in downstream application.
Success
"CADfix has eliminated in-house solid modeling altogether," explained Engineering Manager, Paul Abraham. "We can take files from any system and process them in CADfix before going to analysis allowing us to work with a truer representation of the proposed design resulting in more accurate analysis."
Abraham says that CADfix is, on average, three times faster than previous methods.
"I would estimate that in about 95% of cases we can make a good solid model in a short time with CADfix," he says. "This increases our analysis capacity and boosts the service we can offer our customers. Analysis is effectively completed far quicker, we can perform more design iterations and the end-products are better engineered as a result."
