Representation of circle

Nr. 016
Represent a circle in Monge throught the following problem:

There is P point and t=XY line and T pont on it. Construct a circle passing throught P point and t is a tangent in T point. Show the main diameters of the circle and the tangent of them. P(45, 70, 235); X(45, 100, 275); T(100, --, --); Y(200, 150, 205).

Intersection of a pair of plane sheets

Nr. 012

Construct the intersection of a pair of plane sheets and show the shadow as well. In this problem you can see the construction of transversal, intersection of 2 planes and shadows.

Follow the solution in the link below:

Construct a prism

Nr. 011

New problem from also BME facuty of Mechanical Engeneer. We need to construct a prosm from the given one of the base line and an edge.

See the solution here:

Polyhedron construction (pyramid)

Nr. 010

I found a homework from a faculty of Mechanical Engeneer of BME homepage. Let's see the problem:
Construct a right pyramid with base hexagonal ABCDEF square. The A and B points are laying on the e=XY line, the base circle is given by O, witch is laying down on the secondprojeting plane of e. The height of the polyhedron is m. Choose the right side of the solutions. Show the visibility. X(30,115, 240); Y(165, 40, 50); O(60, 65, -); m=110

Here the construction step by step:

Transversal 3. (normal transversal)

Nr. 009
Special transversal is perpendicular to the skews lines.
Here the steps to the construction:

Transversal 2. (paralell with a direction)

Nr. 008
Second part is to draw a transversal paralell with a direction between two skew lines.
