What does 2x mean on an engineering drawing?
Typical on an engineering drawing identifies a repeated feature. This is identical to a feature which is identified as 2x or 5x. A typical dimension callout will occasionally be followed by a 2x, 5x or similar, to specify the quantity of features which are tolerance the same.
What does H7 mean on a drawing?
The standard (size) tolerances are divided into two categories: hole and shaft. They are labelled with a letter (capitals for holes and lowercase for shafts) and a number. For example: H7 (hole, tapped hole, or nut) and h7 (shaft or bolt). H7/h6 is a very common standard tolerance which gives a tight fit.
What is full radius?
A full radius (sometimes called a true radius) usually refers to a hole in the face of an object that is at an angle, and you need to ensure that the radius called out is true to the surface.
How many types of lines are there in engineering drawing?
For general engineering drawings, the types of lines recommended by the Bureau of Indian Standards shown in table 2 must be used. The thickness of the lines must be chosen according to the type and size of the drawing from any of the six groups given in Table 1.

What do you think of Rp art tickets?
For starters, I think RP Art tickets are magical! There’s so much passion and talent in the drawings players send us, from painstakingly made color-by-pixel MS Paint art that competes with Photoshop prodigies, to players who think drawing a red circle and indicating it’s Vlad in his pool is a pretty funny thing to send us (it is).
What are the different types of lines on an engineering drawing?
Not every line on an engineering drawing is equal. The different options make it possible to show both visible and hidden edges of a part, centre lines, etc. The most common is a continuous line, also known as a drawing line. This represents the physical boundaries of an object.
What is the difference between RP and Ra?
Roughness Average, Ra, is the arithmetic average of the absolute values of the profile heights over the evaluation length. Maximum Profile Peak Height, Rp, the distance between the highest point of the profile and the mean line within the evaluation length.
