schizek Posted August 27, 2003 Share Posted August 27, 2003 I am trying to create a custom profile that wraps around a sheet metal bend. My problem is, the custom profile is more of a pattern, and has several separate notches that consist of one custom profile. When I try to modify the affected bend for it to wrap, it disappears. Is this the intended functionality? Quote Link to comment Share on other sites More sharing options...
schizek Posted September 5, 2003 Author Share Posted September 5, 2003 So.......Is this something that is not possible? Is it a memory problem? Graphic problem? Other? Quote Link to comment Share on other sites More sharing options...
Mike Allen Posted September 11, 2003 Share Posted September 11, 2003 It sounds sort of buggy to me, but I'm having trouble visualizing what you are describing. Why don't you post an example to the group? Quote Link to comment Share on other sites More sharing options...
schizek Posted September 11, 2003 Author Share Posted September 11, 2003 Attached is a file of what I am talking about. One custom profile that includes 3 notches does not work if you try to modify affected bends, but if you do all 3 separately, they do work. It is a lot cleaner if you were able to do this, not only for accuracy but also for tree size. modifyaffected.ics Quote Link to comment Share on other sites More sharing options...
Chris Lohman Posted September 11, 2003 Share Posted September 11, 2003 Scott instead of using the custom profile; use the "Cut Sheetmetal" command in the tools menu to do this. A custom profile has a very hard time stretching around bends whereas the cut sheetmetal was intended to cut through any sheetmetal regardless of how curvy it is. How to use cut sheetmetal: 1) Create your stock/sheetmal 2) Create a solid part (not a shape, but a part) that represents the hole that you want to cut out of the sheetmetal. This will be your cutting tool. 3) Position the tool so that it "cuts" through your part 4) Select the sheetmetal at the part level (blue) then shift+select the tool, then run the "Cut Sheetmetal Part" command from the Tools MENU (not catalog).

Chris Lohman Posted September 11, 2003 Share Posted September 11, 2003 Also keep in mind that as you modify items; they can change their location in the part history. Try unchecking "Allow Reording" which is a right click option on a part in the scene browser before modifying the bend. Quote Link to comment Share on other sites More sharing options...
schizek Posted September 11, 2003 Author Share Posted September 11, 2003 The cut sheet metal tool doesnt always work to give you the correct information. It is basically cutting the sheet metal AFTER form, when in reality the sheet metal is cut BEFORE form. I know it doesn't sound like much, but it is a big deal when you are trying to get correct blanks. Quote Link to comment Share on other sites More sharing options...
Alex Khenkin Posted September 12, 2003 Share Posted September 12, 2003 All this sounds to me like one more voice for the addition of unfolded modeling capabilities. Alex. Quote Link to comment Share on other sites More sharing options...
Chris Lohman Posted September 12, 2003 Share Posted September 12, 2003 The idea with cutting sheetmetal after form is that when you unfold it; our sheetmetal performs calculations to rebuild the cut-shape so that in the unfolded state the cut appears as you would need it to be cut so that it would fold correctly. We don't merely unfold the sheetmetal; we completely rebuild it and all of the shapes within it, taking into consideration k-factor, stock, and the other properties; so that you are given the correct unfolded shape that is required for it to fold properly.

schizek Posted September 12, 2003 Author Share Posted September 12, 2003 If you use cut sheet metal in certain bend areas, the unfolded sheet metal thickness is cut at an angle, which is not correct. The idea of getting it to fold properly is important, but just as important, if not more important, is being able to create the proper unfolded sheetmetal.

Chris Lohman Posted September 12, 2003 Share Posted September 12, 2003 Ah well if there's a bug, such as cutting at an angle, then we'll certainly correct it I agree to the usefulness of cutting in the flat. Quote Link to comment Share on other sites More sharing options...
