Problem in creating surface

[skwasim_smile]

hii everyone,


Coming back to the forum after a very long time,I have received a file in IGES format which has only curves for the model,I have to build surface using these curves below attach picture will give you perfect idea,My problem is that boundary requires 4 curves to build surface but there are some areas in this model which has six curves,I can't split these curves adding extra curves as I don

Hi,


you can use n-sided surface which may or may not solve your problem. however you have an option to break the six sided surface into 4 sided and three sided surface. you can use Boundary blend to create a four sided surface and you can use style feature to create a three sided surface(not in 2001).

most are probably planar anc could be created simply by using the fill feature- however - it would be a more robust model if you simply rebuilt it. probably would be quicker too

The screenshot made me reminisce....


I did a class several times... Sheetmetal class where it required two days of surfacing as a preliminary. The manufacture would get iges geometry in from a customer that created their sheetmetal parts not using a sheetmetal package.... ie. the walls were not all nominal wall thickness in some places by .001 and the radius did not match everyplace minus the wall thickness ie. inside radius was off from the outside radius. By and large the challenge was three fold. Solidify the iges. Convert to Pro/SHEETMETAL then create a flat pattern.

When I first zipped the gaps in the sheetmetal import it was clear the user was using a non sheetmetal mode and the header in the iges file told me the part came from soldworks. <those users tend not to be very hi end (I like spreading that roomer) So the solution was to use surfacing to get the nominal wall and delete any surface geometry that would impare the conversion to sheetmetal. All the walls have to be the same thickness or it does not meet the definition of a sheetmetal part.
