ReMark Posted November 24, 2014 Posted November 24, 2014 (edited) its true ?? Your front and side views don't look exactly like what is pictured in post #1. Your top view is incorrect and your dimension text height is a bit too small . There is also an extra line on the right hand side of your top view to the left of the circle. How did you get a dimension of 412,63 for the length? Isn't it supposed to be 4.12? Are all views supposed to be fully dimensioned for this exercise? Does anyone else here think this exercise was meant to be done in decimal inches as opposed to millimeters? Edited November 24, 2014 by ReMark Quote
ReMark Posted November 24, 2014 Posted November 24, 2014 Your three views should look like this. Keep in mind that the opening seen in the front view passes all the way through. Quote
ReMark Posted November 24, 2014 Posted November 24, 2014 For demonstration purposes only. The 3D model is incomplete (no holes). On the left we see the two channels cut through the object (front-to-back & side-to-side). On the right is a section created using the Slice command. See how the opening that passes through the object from front to back partially cuts into the vertical leg? Now do you understand what is happening and how to show it in the top view? Quote
Dana W Posted November 24, 2014 Posted November 24, 2014 Does anyone else here think this exercise was meant to be done in decimal inches as opposed to millimeters?Yes, it probably should have been drawn using the imperial units (inches) template. That is one of the problems with on line classes, if this is the case. Not enough direct communication. Quote
Dana W Posted November 24, 2014 Posted November 24, 2014 Those wacky dimensions could also be the result of an error in drawing the rectangle while looking at the drafting tool tip display to establish its dimensions rather than using the dimensions option of the rectangle command. That explains the tiny dimension text, if the object is 10 or 100 times too big from the start. Quote
nestly Posted November 24, 2014 Posted November 24, 2014 How did you get a dimension of 412,63 for the length? Isn't it supposed to be 4.12? Those wacky dimensions could also be the result of an error in drawing the rectangle while looking at the drafting tool tip .... The Rectangle is drawn with the correct dimensions.... the OP apparently inadvertently snapped one end of the dimension to the end of an existing dimension instead of the rectangle. Regarding easymike's question, the answer is apparently "Yes" as there's a frozen layer in the drawing in post #18 with all the construction geometry. Quote

If the dimensions in post #1 were metric then 4.12 would have been written as 4,12 right? gokhandmr: Is this an assignment you got in class from your instructor? Quote
JD Mather Posted November 24, 2014 Posted November 24, 2014 If the dimensions in post #1 were metric then 4.12 would have been written as 4,12 right? Depends on country and standard used. ASME/ANSI Y14.xxM uses dot . as decimal separator. Other countries/standards use comma , as decimal separator. The units weren't specified, but my inspection and logic (and experience in edu setting and knowing what book that image came from, the units are inches). 4.xx overall mm would be so small a part that logically doesn't make sense in most cases.

gokhandmr Posted November 24, 2014 Author Posted November 24, 2014 yes it is. i understand all draws but when i start the draw all times some thing is wrong like hidden layer .. i must working a lot thanx for help and again sorry my bad englih:) Quote
Dana W Posted November 24, 2014 Posted November 24, 2014 The Rectangle is drawn with the correct dimensions.... the OP apparently inadvertently snapped one end of the dimension to the end of an existing dimension instead of the rectangle. Regarding easymike's question, the answer is apparently "Yes" as there's a frozen layer in the drawing in post #18 with all the construction geometry. The drawing is in milimeters, and the dimension text is 2.5 mm tall. The right to left measurement of the object is 412 mm, not 4.12" as it should be according to the example plate from the lesson. Apparently it should have been drawn in inches from the start. Quote
ReMark Posted November 24, 2014 Posted November 24, 2014 ???? It is dashed because it is below the surface that you can see. It would not be shown using a continuous line. Quote
