Dimensions

[Anonymous]

Having an issue with dimesions wondering if anyone has come accross.

Basically if we dimension any geometry which is not square on to the view, then any text placed in the 'below' field of the dimension will display upside down and clash with the dimension itself. Suffix and Prefix fields however still work fine.

Image attached, any thoughts or a fix would be greatfully received.

I could not replicate it ....It works fine ,with no fault...Maybe you should try to uncheck Use Hardware Acceleration (R >Options>Graphics)

Thanks for response, had tried with and without hardware acceleration to no avail. 

On further investigation, issue only appears if the read convention is set to 'Right, then Up' or 'Left, then Up'...

That's the problem. Set read convention to "Up, then Left" (or Right, if it is best for you).

Thanks also for response. 

I think issue is that we have both a croocked L shape building, and some views which are on sheets at 90 degrees to project north. In order for text to display as we want to read it, then as far as Revit is concerned, its upside down. What's strange is that this doesn't cause a problem, other than if we add labels to openings using the 'below' text field. 

In any case, thanks both for your thoughts.

@Anonymous are you rotating the viewport on the sheet?

Hey @pwking

The problem is not what is right for one to use; the problem is using the right convention for the right annotation/dimension!!! And from the image you posted; you are using the wrong convention for the used annotation.

The reading convention is derived from the  mathematical illustrations of the two-dimensional Cartesian systems (X & Y) normally used for Reading National Grid Coordinates, where the coordinates are measured along the horizontal X axis (to the Left or Right of the grid). And the second coordinate is then measured along the Y axis, usually oriented from bottom to top ie UP towards the North (ABOVE OR BELOW the Grid). That is where the Above and Below text fields come into play...When you allocate a point on the grid one should USE LINEAR DIMENSIONS and not ALIGNED DIMENSIONS...Aligned dimensions are not defined by Above and Below but they are defined by Distance + DEGREES.

If one served in the army and every been in a tank or in the artillery should know how coordinates for a target along the direct vision is measured using either distance + degree/hours OR X and Ys...If one served in the infantry one should know a similar convention using the Hours instead of Degrees (the latter almost never use the X & Y

Convention for NG Readings (Linear Dimensions)

- Left then Up (Measure N units along X axis to the Left then M units along Y Axis) North UP

- Right then Up (Measure N units along X axis to the Right then M units along the Y Axis) North UP

- Up then Left (Measure N units along Y axis then M units along the X axis to the Left) North UP

- Up then Right (Measure N units along Y axis then M units along the X axis to the Right) North UP

Remarks:

1. If one sails (as a profession or hobby) know why there is only UP in this convention and no DOWN
2. Consider an example of a 5000mm aligned diagonal dimension which reads Left then UP...no surveyor in the world would be able to locate it. He will need the either the X and Y (ie: linear dimension => u can use the Above and Below) OR 5000mm + N Degrees (ie: Aligned Dimension)
3. When you use Aligned Dimension and you want to indicate that the end coordinate is below the Grid you would use (360-N degrees) as shown below. That will indicate it is in the negative direction below the grid.
