Volumes and Surfaces.

On the  21st of April we learned to build different shapes using several commands.

Using pline command we drew the shape and extruded it normally, perpendicularly to the plan.

We drew an inclined line towards the plan and extruded the shape choosing Direction.

Then we drew a circle and an inclined curved line (command spline) and extruded choosing Path.

We can make extrusion -choosing taper angle.

We built a cylinder by extruding a circle. It was solid. To make it empty inside, we made another cylinder by extruding a smaller circle, fitted it to the first cylinder and substracted.

 And decreased the transparency of their layer.

Another substraction between cylinders.

We can fill the different polygons with the tool region  and use substraction command.

After building the "construction" for the new surface, we used the command: Edgesurf .

We can Thicken it.

To create a loft  we drew three different circles with different heights and use command: Loft.

 We can create a Section.

After exploding the loft we can thicken it. We can manage the direction of that operation with the sign in front of the number (- , + )

 We can create different lofts with different shapes.

If we cover two same lofts with the boxes and substract them separately, we can see the inner side of the lofts and these parts can fit each other and be presented in different colours.
