Open the note properties. (To do that, right click on note and select properties or double click the note). On the text style tab, check the “Break crosshatching” in. This will break the hatch. The margin input refers to the empty space around the text.
Involute curve also known as evolvent curve is a kind of differential curve. In mechanical engineering this curve is used a lot in gear design. This curve is used to get the gear tooth profile and when two gears of this profile mesh, the instantaneous contact point is only one and it moves along the curve profile. This property is known as line of action or line of Contact or pressure Line and this is why it is used extensively in gear design.
Overwriting dimensions is a very useful and handy option. We can replace the default dimension with any other number or text. Here we will see how to overwrite an dimension and some of the usage. Overwriting a dimension with any other number is not preferable but it is very useful to make notes like the ones shown in the below pictures.
ProE/ Creo creates versioned files every time you save a part, drawing, assembly, etc. That means if you save a part 10 times you can see 10 part versions in the folder it is saved.
To delete old versions of any part, drawing or assembly alone, just open it in the ProE/ Creo and then open the file menu from the main menu (See the picture below). You can see an option called delete. If you expand this you will see two options.
Light is a electromagnetic radiation. It travels in wave form with infinite number of energy pockets called “photons”. As we all know, a wave form has amplitude, frequency and wave length as its main parameters.
The speed of all electromagnetic radiation or EM waves in vacuum is 299,792,458 meters per second. So no matter what the parameters are, if waves start from a point at a time, they will reach the other point at the same time.
Celsius, Fahrenheit and Kelvin are the units for measuring temperature. A temperature value can be expressed in any one or all of the above units independently. The values can be converted from one unit to other unit still keeping the meaning same.
We use the number 273 (273.15 exactly) to convert from Celsius to Kelvin and vice versa.
