Dimension in drawing not accurate

[Karol-Or]

The diametric dimension on the right, dia. 244.9 isn't resembling the real dimension in the weldment.

You see in the sketch of extrusion 2 that i gave an internal diameter of 245.

Unable to open your assembly and drawing file but I suspect you have set your dimension styles to 0 decimal places for you drawing.

[Karol-Or]

no, i didn't set the accuracy in the drawing to 0 decimal places, it is for 1 place.

Some other dimensions in this drawing also became a bit smaller, at about 0.1, like this one.

It seems the part, in the drawing, is shrinked a little in the Y direction.

Also the hatch in the section view is incomplete, it doesn't reach the boundary at a place.

Do a Pack-and-Go to get all the files. Open Windows Explorer and locate the IDW, RMB on the IDW and select the Pack-and-Go to collect all the files and zip them.

I made pack and go

Your "Primary Unit" was set to 0 decimal places. The Tolerance was set to multi decimal places.

Blair - did you check the Sketch2 dimension (I forget whether it was in Prep or Machining) in the Weldment.

[Karol-Or]

Not the accuracy is the problem, i entered a round 250 diameter dimension in the model, and you can see it if you open the sketch in the part.

All the diametric dimensions in this drawing are shrinked a bit, but not the horizontal dimensions

Are you sure that your section line on the drawing is passing directly through the center?  If not, that could cause the diameters to appear slightly smaller (since you're not cutting at the full diameter), while not affecting the linear dimensions.

Good catch!

These two holes do not share the same center line.

The cutting plane is 5mm left of the center.
