perpendicular extrusion to the surfaces below

[psx2]

Hello everyone,
I projected a rectangle on different surfaces now I would like to create a perpendicular extrusion to the underlying surface group.
How can I do that?

Thank you.

hi psx2, to do as you say, just go in the options, under "object"/"superfici", put or remove the check mark to "create normal extrusions to the planar base" according to what you want to get,

Thanks tester, you know the option but it tilts me the sup even where the base stands on a flat area!
Thank you.

Then I don't understand what you want to do, with that tick, or it makes you a normal extrusion on the plane where you projected the wireframe, or normal to the active main axis, if maybe a photo of what you want to do, I can be more of help. . .

basically create a horizontal line one at 45 degrees and connect them with a r10 for example then create an etrusion.
now create for example a rectangle and project it on this surface, then a part of the rectangle will be projected on the flat surface a part in the fitting and a part in the part to 45o
Now doing I would like the extension of the rectangle to happen in a perpendicular way to the underlying sup so straight where the base sup is straight and to 45o where the base sup is tilted.
I hope to have explained better otherwise as soon as I can place a video.thanks

I probably don't understand... basically you want to get an extruded solid, with the "cut" base with the surface you created? or, do you want the solid to be created by an extrusion that rises perpendicular to the part at 0° and a part is extruded perpendicular to the area at 45°? in the 1st case is a logical thing, in the 2nd limit you have to do 2 separate extrusions, join them, then put the chord on the edge, but nevertheless I do not understand what sense would a solid of this form... If, as you have already written, put a video or even a hand-made sketch, it could be more explanatory,

red is the basic sup and black is the extrusion of the rectangle.In theory there should be a connection between the two red lines but it changes little, I think.
Thank you.

We begin by saying that each cad is based on mathematical rules, that you cannot bend to our will, in the sense that, a 2d profile, that in your case is projected on 2 different planes, must nevertheless submit to these logical rules, for which an extrusion can only be made perpendicular to the plan or perpendicular to the active axis (x, y or z), but to get what your logic is 1) the surfaces where you projected the wireframe, must not have any connection, but there must be the edge, so, draw a line on the edge, so as to divide the rectangle into 2 rectangles, create a curve composed for both, extrude them each perpendicular to its starting surface, join them, then do the fitting; 2) do an extrusion using the profile you designed, as if that were the main extrusion axis, (practically extrude the flank)

Thank you.

If you want it to be perpendicular on all surfaces (which are not parallel to each other) you should project on one surface at a time and extrude one at a time. the result is right at the first stroke, otherwise it is twisted in most cases. remember not to remove the dependencies from the curves, otherwise it loses perpendicularity (I hope I understand correctly)
