Lofted Sheet Metal from 3D sketch profile

Hi Expert,

 

I have some issue here where I want to create a loft function in sheet metal using 3D sketch profile but failed.

 

Basically I want to use loft because I want to get the triangular line bend. (can refer my attachment)

 

For now what I do is by using surface and thicken it and blank it without the triangulation line. Is there anyone here able to do it?

Please refer my attachment.

First thing - I can't see any attachment.

I'm not sure if 3D sketches are permitted, but if they are I think they will still have to be planar sketches.

Hi @beachcomber,

Thanks for the reply
My 3D sketch is not planar. refer the attachment.

Hi~ Arisy

do not know if I understand my explanation.
loft Flange does not support 3D sketching.

By the proposed method
1. Loft in a 2D sketch.
2. After that, cut it as shown in attached SM1 figure.

This is the only way.

Hi there @Arisy,

 

As others have mentioned, you are better off creating a "standard" lofted flange frome planar sketches first, then use "Normal Cutout" to get your desired final shape, that matches your 3D sketches.

It would take a fancy press brake to form that in one piece!

Hi

 

Thanks for the reply and suggestion. Now I have some idea.

Of course later on I will split this whole sheet metal into few pieces.

Hi Sean.

 

Is there any faster way to calculate the length of the triangulation lines that I did here? Currently I need to calculate manually one by one by using DIstance between Dimension which need me to point starting point to the end point to measure.

Hi there @Arisy,

 

I presume you are going to dimension this out for manual fabrication? [or do you need this for another reason, and in the 3D "Flatten" view??]

 

I would probably do that in the flat pattern view, from Draft, and just use Smart Dimension on the bend lines, laid out accordingly.

Hope that helps.
