9 Tips for Better Engineering Drawings that Save Time and Money
- Tip #1: Dimension only critical & measurable features.
- Tip #2: Communicate hole tapping needs with thread size and depth.
- Tip #3: Consolidate call-outs when multiples of the same feature exist in a view.
- Tip #4: Communicate assembly intent of critical features.
How do you draw a general Pentagon?
Answer
- Draw a line AB of 4 cm.
- Draw a perpendicular.
- Using protractor measure 45° and 60° with centre as A.
- Mark the points on the perpendicular 45° as 4 and 60° as 6.
- Now bisect the points 4 and 6.
- Name that point as 5.
- Now with centre as 5 and radius as 5 to A draw a circle.

How do you construct a pentagon?
A regular pentagon is a five-sided polygon with sides of equal length and interior angles of 108° (3π/5 rad). Because 5 is a Fermat prime , you can construct a regular pentagon using only a straightedge and compass. 1. Draw a line segment AB. 2. Draw two circles, 1 and 2, centred at A and B, both with radius AB.
How many pentagons to make a 3D Pentagon?
It has D 3d symmetry, order 12. It has 2 sets of 3 identical pentagons on the top and bottom, connected 6 pentagons around the sides which alternate upwards and downwards. This form has a hexagonal cross-section and identical copies can be connected as a partial hexagonal honeycomb, but all vertices will not match.
