Transition Sheet Metal

This command allows you to create sheet metal between 2 sections. (for example, a hopper)

Creation stages / Use:

Click the icon or select Sheet metal > Transition Sheet Metal... from the drop-down menu.

Check Surface Only to not manage the width. The sheet metal will be a surface sheet metal.
If the option below is not checked, enter the thickness of the sheet metal.
Indicate whether or not the dimensions indicated are external dimensions.
Select the transition type.

Point and Point: Allows you to define the transition by 2 points.

Select the first point.
Select the second point.
Select the orientation of the sections. (X direction of sections). Must be normal to the direction of the 2 points.

Point, Direction and Height: Allows you to define the transition by a point, direction or height.

Select the first point.
Select the direction.
Enter the positioning height of the second profile.
Select the orientation of the sections. (X direction of sections). Must be normal to the chosen direction.

Point, Direction and Point: Allows you to define a transition by 2 points and a direction.

Select the first point.
Select the direction.

Select the second point.

Select the orientation of the sections. (X direction of sections). Must be normal to the chosen direction.


No Orientation	With Orientation

Select the geometry of the first section and inform the dimensional values. If the geometry is not proposed or if it exists, click User section and select the profile.
Enter the incline angle of the first section. If the incline is not around the proper axis, the orientation of the sections must be modified (see explanations in section 4. Choice of transition types below).
Select the incline direction of the first section. It is preferable to select the same direction as the direction between the 2 sections.


No Incline	With Incline

Select the geometry of the second section and inform the dimensional values.
Enter a longitudinal and/or lateral shift value if necessary.


Without shift	With shift

Enter the orientation angle that allows you to turn the second section around the direction.


Without Orientation	With Orientation

Enter the incline angle of the second section. (see above images)
Select the inclination direction for the second profile.

If two sections use Circle mode, the Conical surface option will be available in the second section. This option ensures to have a surface strictly developable, to the detriment of the geometry of the second section which will no longer be strictly circular. The position of crunching lines will be modified accordingly.
This option does not allow a lateral misalignment.

Obtained shapes comparison with and without the conical surface option.

Obtained shapes comparison with and without the conical surface option.

The blue surface is obtained without activating the Conical surface option. the blue section is circular. Blue lines on the surface are used for the crunching surface.

The green surface is obtained by activating the Conical surface option. The main surface of the shape is an angled cone. The green section is an ellipse. Green lines on the surface are used for the crunching surface.

The superposition of the crunched lines shows the difference between these 2 constructions.

Unfoldings comparison.

Both unfoldings are really different. (the unfolding with blue lines comes from the blue surface, green lines from the green surface).

It is not necessary to create profiles before creating the transition sheet metal, except when profiles are created by the user.
If the second profile is identical to the first (without orientation or offset), check this section.

You cannot use both a standard profile and a user profile. If the user profile is used, the 2 profiles must be created by the user.
the user section mode can only manage sections with a similar type as those proposed with others modes (circle, ellipse, square, rectangle, slotted)
There are no values to enter for user profiles. It must be well positioned and oriented.
