hi all im trying to do a simple sketch on solid edge and when i create the first dimension it is automaticly being placed as a driven dimension (blue color) and when i try to change it in to a driving dimension by pressing the lock i cant because its in grey and doesn't work , its not possible...

thanks everyone , you have been very helpful

hi all, I'm designing a part that has 20 holes in it in a 15 mm distance from the datum A (see in attached picture) , whats important to me is that all the holes centers will be on the same plane within 0.01mm , i dont want to place a +-0.01mm tolerance on the 15 dimension because its not...

hi, can anyone tell me what material is used to make collets? if there is more then one option its even better

what about this? (attached file)http://files.engineering.com/getfile.aspx?folder=5025343b-c091-410a-a6ae-90d281f1bcc3&file=Z07170.jpg

hi all, i recently received a drawing of a part that had a hexagon shape , the guy who made this drawing used a symbol to indicate that this is a hexagon, you can see an example of the symbol he used in the attached file, it looks like the diameter symbol but with a hexagon instead of a circle...

hi everyone, i have a question about symmetry in drawings , what is the correct way to indicate symmetry on a drawing in such a way that i wont have to write the dimensions of features that are in the middle of the symmetric part , its a little hard to explain in writing so i have an example in...

thanks for the answers! very helpful

hi, Can anyone tell me why there is a shiny coating or glaze on ceramic insulators? thanks

the kind of plastic that is used to make plastic toolboxes will be good, do you know what kind of plastic it is?

hi all, i need to choose a material for a product i'm designing , the product looks like a hollow dome (half a sphere) , and it needs to be made of plastic , this product has to work in rough conditions so it needs to be pretty strong but not too expensive , what plastic would you recommend for...

sorry, cant say what its for but the accuracy demand is necessary

thank you all, you have been very helpful

hi, I need to make a drawing for a part that has a flat pattern in it (you can see a picture in attached file). I want to know if there is a standard way to give a patterns dimension without going one by one and giving all the dimensions , for example in my part the distance between the holes...

how do i make a "non-bending" specialized micrometer that is at least 300 mm long and still light enough so a man can hold it while he is measuring?

cant use what ajack1 suggested or mintjulep because the part is very long (about 400 mm ) and i need to measure the thickness threw all the length and this plier shaped devices are not accurate enough when they are long because they bend

the client uses an XYZ machine to inspect it , the shape is opened so its not a problem to insert a measuring device inside , it looks like a an egg that was cut in half

hi, i need to measure the wall thickness of a certain product , the product is made of ceramics and has an egg like shape which makes it very difficult to measure, in addition the wall thickness is not constant and varies along the profile . the average wall thickness is about 8.5 mm. i tried...

the machine were using is a small centerless grinding machine, its made out of two wheels- a grinding wheel and a regulating wheel that moves the parts, the parts move between the the two wheels , the accuracy level required for the diameter is +- 0.01 mm

I need to grind small cylindrical parts (diameter of about 1mm , length 3mm)made of hard steel and tried to do it with a small centerless grinding machine. But because the parts are so small they are flying everywhere and it’s impossible to get them between the two wheels of the machine. The...
