Proe Function / Relation to round the decimal places

Its strange that ProE does not have a ROUND function. At least I counldnt find it.

It has two funtions.
Ceil will always round it up.
Floor will always round it down.

I have used both to get the ROUND functionality.
here is the relation...

X is the original value.
D is the number of decimal places.
X_New is the rounded value.

X = 1.334
D = 2

X_ = X * 10^D
XFLOOR_ = FLOOR(X,D) *10^D
IF X_ - XFLOOR_ < 0.5
X_NEW = FLOOR(X,D)
ELSE
X_NEW = CEIL(X,D)
ENDIF


try and let me know if it works.

its simple & its really great

A simpler trick is to ad 0.5 to the dim adn then use the FLOOR command. For example, 1.3 + .5 = 1.8. FLOOR of 1.8 is 1.0. However, 1.8 + .5 = 2.3 and FLOOR of 2.3 = 2.0.

Man, my spelling/typing is bad, sorry.

That's pretty simple, Doug. Thanks.

Joe & Doug,

I am trying to insert a counter sink angle dimension into the same dimension as the hole. I am successful with the following,

3X dia_sym @D
c'sink_sym dia_sym &d68 X &angle

where "d68" is the diameter of the counter sink and "angle" is the relation "angle=2*d69". d69 is half angle of the countersink - and this is because the hole sketcher only allows for dimensioning between the centerline and the edge of the countersink.

The problem is that I want the "angle" dimension to be 82 and not 82.000. I tried both of your tricks and even if I use &X_NEW in the dimension it still comes out 82.000.

Suggestions?

Jeff

Try adding [.0] after the dimension. This tells Pro|E to round to display the dimension to zero decimal places.

The 0.5 addition to floor function is absolutely brilliant. Thanks

I think that doesn't work if X is negative.

hello Anonymous,
please add an if condition to the logic of adding 0.5.

TreeView Structure in Excel VBA

TreeView is extreamly useful in specific cases but it can be bit tricky sometimes to implement.  Last Few days I was working on a TreeView Structure and thought I will share the knowledge I gained...  This post takes you through the basic operations to create and operate a TreeView. It will be like the Folder tree window of the windows explorer.  Moreover, you can have it dynamically updated based on the data in excel.... Here we go..

Its been a while since I have done some posting. This option in excel is something which I thought would be very useful for many. Its the TABLE Function in MS Excel. This is especially useful in the following scenarios.
