    Problem with tol_text_height_factor in .dtl

    It is just to Plus-Minus tolerances that I am trying to adjust the size on.

    Problem with tol_text_height_factor in .dtl

    Hi, When I adjust the tol_text_height_factor in the .dtl nothing happens. It is my understanding that when I change this ration, the size of my tolerances in the plus-minus format should change accordingly relative to the dimension text size. Oddly enough the tol_text_width_factor seems to...

    Proe metric units

    Two questions 1. Recently upgraded from wildfire 1.0 to 2.0. Looking at the metric unit systems available in 2.0 (CPS, MKS, mmNS & mmKS) it seems to me that mmKS is new to 2.0. Can anyone confirm??? I know longer have acess to 1.0. 2. With respect to the mmKS and mmNS systems does anyone...

    roundness / circularity

    The roundness is not specified although I am assuming it should not be greater then .1. I am dealing with an o-ring groove for a seal designed for minimal o-ring compression so both the size and roundness is of importance, especially if the roundness is throwing the groove out of size. The...

    roundness / circularity

    I am measuring a large diameter of 100mm on a CMM. The tolerance on the interal diameter is extremely tight +/- 0.05mm. A lot of my measurements have had roundness values greater then the tolerance range > 0.1 which I have considered to be out of spec. Is this correct? Also, some have...

    Magnetic strength behind non magnetic enclosure

    For my application the sensor is stationary and ferromagnetic targets pass in front of the sensor at relatively consant rate which may range anywhere from 1 to 50000 pulses per minute. Would I be correct in inferring from the above posts, that for my specific application that materials with...

    Magnetic strength behind non magnetic enclosure

    My question is a general one and my knowledge of magnetics is somewhat limited but I will try to be more specific. I have a magnet inside a plastic material of a known thickness. If I switch to another material, be it plastic, rubber, or cardboard, will the strength of the magnetic field...

    Magnetic strength behind non magnetic enclosure

    I am looking at new enclosures and encapsulants for some magnetic based motion sensors. The materials used are nonmagnetic. I am not quite sure how much of an affect, if at all, changing these materials would have on the sensors ability to pick up pulses generated outside the enclosure (ie...

    machining glass

    Can glass (specifically borosilicate) be machined using typical processes or are there special consideriations and processes required.
