In the isometric system there are three equal axes at right angles to each other.
They crystallize in different systems, the more valuable gem belonging to the rhombohedral, and the less valuable to the isometric system.
Crystals are arranged in six systems, based upon the number and relations of the axes, as follows:— Isometric System.
Isometric system, occurring usually in distinct crystals, the cube and the twelve-sided form known as the pyritohedron being the most common.

A new specially ruled paper to enable you to make sketches or drawings in isometric perspective without any figuring or fussing.
Sulphide of mercury inisometric form and black in color.
Isometric projection enables one to show the length, breadth, and thickness of an object drawn to scale on the one drawing.
A figure may be drawn so as to show an isometric or a perspective view.
Isometric means a method of drawing any object in such a manner that the height, length and breadth may be shown in the proportion they really bear to each other.
Thus, a cube can be drawn so as to make an isometric figure, as in Fig.
The relative lengths of the crystallographic axes is a very important feature of all crystals except those of the isometric system in which the axes are always of equal length so that the ratio is 1:1:1.
When a ray of light enters a crystal or crystalline mineral representing any crystal system except the isometric it is doubly refracted (i.
A sulphide of zinc commonly in crystalline form belonging in the isometric system, especially in tetrahedral combination forms (see Figure 75b).
Commonly crystallizes in isometric octahedral forms alone or combined with twelve-faced forms.
Isometric crystals only are singly refracting and hence a ray of light is not affected in passing through them.
A sulphide of iron which commonly crystallizes in the isometric system mostly as cubes, twelve-faced pyritohedrons, octahedrons, or combinations of these.
The members of this very interesting mineral group very commonly occur in isometric crystallized forms, mostly twelve and twenty-four faced figures or both combined, as shown by Figure 72.
Isometric crystals, nearly always in cubes with three good cleavages at right angles, and parallel to the faces of the cube.
Commonly as isometric crystals either as cubes or combinations of cubes and octahedrons.
Crystals of usually octahedral habit in the isometric system.
Many crystals outside the isometric system also exhibit a remarkable tendency to absorb light differently in different crystallographic directions, thus producing two or three color tints, which vary according to the substance.
The method of making the breaks is shown in the photographs and by the isometric sketch at F, Fig.
The red oxide of copper; red copper; an important ore of copper, occurring massive and in isometric crystals.
A white or fleshÐred mineral, of the zeolite, occurring in isometric crystals.
Physics) Not isotropic; having different properties in different directions; thus, crystals of the isometric system are optically isotropic, but all other crystals are anisotropic.
To make isometricperspective drawings you can get along without the cross-section paper described above though this is the easiest and most accurate way to get results.
You can go ahead now and draw lines ⅛ inch apart parallel with each of the three lines and you will have a sheet of isometric cross section paper of your own making.
The lines which cross the vertical lines on isometric cross-section paper are 30 degrees from the base, or horizontal line and the vertical line is, of course, 90 degrees from the horizontal as shown in Fig.
When making isometric ellipses much care must be taken to make all the points and draw all the lines with the greatest accuracy as the slightest error will distort the whole thing.
Now the lines formed by marking off angles of 30 degrees are the only ones you will have to make for isometric perspective.
The diamond is native carbon in isometric crystals, often octahedrons with rounded edges.
A solid in the isometric system, bounded by twenty-four equal triangular faces, four corresponding to each face of the cube.
A sweet amorphous deliquescent substance obtained indirectly from benzene, and isometric with, and resembling, dextrose.
It is a hemihedral form of the isometric system, allied to the tetrahedron.

The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "isometric" in a variety of sentences. We hope that you will now be able to make sentences using this word.
