equal sides

[gryles]

Hi

I have a .ipt file attached of a shape in which the shape is correct except i cannot get the 4 sides all to meaure 40mm..2 sides measure approx. 26mm and the other 2 sides approx. 55mm...how do i work out the correct angles to get all 4 sides to measure 40mm or is there a better way to achieve the 40mm sides...

Kind Regards

The root of your problem is the definition of your work plane - the angle of that plane will determine the relative lengths of the sides.  Draw a sketch on the front of your block with a line dimensioned as shown and then create a workplane using that line and a point constrained to it's centerpoint (or either end - doesn't matter.

Then you'll have to project that same point onto the cut profile sketch and dimension from there.  See attached.

Hi Mikah

Thanks

I had a go using your attached picture.I attached the .ipt file ..i did not get the sides to 40mm but i did get them much closer then first attempt..is there something i have missed or made a mistake

Kind Regards

Thanks Ravikmb5

Yes they are 40mm sides except there should be a slope above the 4 cuts and not flat

thanks for the help

You are close - the only thing you need to do is delete the 53.319mm dimension in this sketch and, instead, add a coincident constraint between the point you projected and the line the 53.319 dimension locates (see green arrows).  Then you can adjust your dimensions in the first sketch (the two 20mm values) to achieve whatever length you want on the sides.

I can not see the actual part ( I am with IV2010) but it seems pretty trivial part to model. At least by the look at the picture provided. Here it is the part in IV2010.

Hi Igor

That is good...thank you and appreciated....the only step i need to change is where the Revolution 1 uses a curved sketch i need it to be straight line...if using a straight line instead of the curved line will all the steps you use still work?

Again thanks

Hi,

Since I don't know the exact design intent - here is an iPart which documents some possible scenarios. I think the member Part1-03 ( I left it Active) reflects what you are after.

Best Regards,

Igor.
