“Rafi Style wrote at 6:10pm from facebook Hey …i am having problem with sweep boss/base function. I need to make a pipe for which I have made the required 2d geometry with fillets of 5mm in corners..When tried to sweep it says two reason that i am unable to understand a)the path passing too closely to itself b)the way the section twists as it moves along the path Plz help me in this…. “ From my understanding his problem is somethings like this… Let’s analyze why? I’ve suspect it cause by 5mm bend. For this example is 0.25in. When it sweep circle at the bend is overlapping.. to correct this adjust bend radius! See for radius bend 0.5in is barely touch with each other. Let’s sweep it again. For summary, minimum radius at bend is equal or larger than radius pipes. Solved!
