How can I achieve this?

[pashkatarakashka]

I'm sure the folloing model is very easy to make, but I'm very new to this, so need some help...
The illustrations you see below is very rough, the best I could draw using extrude and pattern, to give some idea what I want. Apparently you see the bottom should be smooth unlike below, just like the spline. Also each triangular object should be consident to other. Pattern is required to make it easy modifying the angles of triangular object. Below I just sketched "house like" profile, then extruded and made pattern. If I just make the bottom part separately using sweep rectangle on spline shape, then how to attach this perfectly to array of triangular objects? I also had difficulty to align perfectly each triangular object in array... What is the best way to achieve this object?

Hello;

Make a curve and add a point on that curve. Then pattern the points along the curve. Create the triangle referencing the first point, making sure to use a tangent or perpendicular sketch entity to properly align the triangle along the curve. Now make a reference pattern of the triangles.

You probably also need to make a thin extrusion in the shape of the curve and give it some thickness away from the triangles to smooth out that side of the solid. Otherwise you are always going to have some jaggies from the individual triangles.

You can also pattern the triangular shape as a cut so you won't have the jagged shape from overlapping triangular extrudes. Or just use the spline curve to cut the overlap.

Seems like you can do it in a single sketch from the side. Sketch the spline and triangle tops all at once, then extrude. Not sure if pattern will give you enough control of the design; as it patterns around an inside corner, the tops of the teeth will get closer together...an outside corner will make the teeth further apart. Not sure if you are looking for that result.
