Deform a hose from design position to straight

Deform a hose from design position to straight

Deform a hose from design position to straight

(OP)
I am trying to find out the best way to take a hose and two tubes from its design position and straighten them out. The two tubes are crimped on either end and I need to find out the angular relationship between the first bend on tube #1 to the first bend on tube #2 after it has been straightened out. All I have currently is the design position. I was hoping Deformable part could get me there with just swapping out the design position swept path for a straight path of equal length. ???

The two tubes are being bent simultaneously with two separate benders while the hose is held in the straight position. To properly set up the benders I need to know the angular relationship or clocking on the first bend of one tube to the other.

Unfortunately the F1 key and/or on-line help is disabled here.

RE: Deform a hose from design position to straight

Actually this is not what 'Deformable Part' was really intended for. Rather what you want to do is design some part showing its 'as-assembled' shape but which allows you to change it to its 'as-manufactured' shape and that's what I've done with your example.

First I converted your model into an Assembly since in reality that's what it is, a hose with 2 formed sections of tubing assembled to it. Now that it's an Assembly, I can constrain at least that section of tubing which will move when the hose is shown straight. One other thing I did was reorder your model so that the new path (sketch 'SKT-001') was created before the tube in the Part Navigator.

OK, now all you have to do is EDIT the 'Tube' feature changing it from a formed into a straight shape. To do this just double-click the Tube feature and when the dialog comes-up, simply DESELECT, by holding down the 'Shift' key and selecting, the 3 highlighted curves which make up the curent path of the Tube. Then while still in the edit Tube dialog, select the new straight (blue) path and hit OK. The Tube feature will be recreated and since the section of tubing was constrained relative to the end of the hose, it will move so that it's still assembled relative to the end of the hose.

Anyway, open the attached assembly file and do what I described above.

Hi,
maybe with Edit->Surface->Global Shaping

Thank you...
