I'm trying to input the price for the number of fixtures in my schedule. I added "count" in the fields. However, when I try to create a calculated value, I dont see "count" to be inputted into the formula. Why wouldnt "count" be listed for the formula??
View 5 RepliesI created calculated value Plot Ratio (Gross Floor Area/Site Area = Plot Ratio) but it come out result is "0". Any reason why it didnt calculted properly or what is the correct formula to achieve the coreect answers?
Please see Attached.
We usually run our own calculations for U Values using the BRE Calculator (UK Building Research Establishment).
I just carried out an experiment to check the value that appears in the Revit properties of a wall type (Heat Transfer Coefficient - U) for a given wall build up.
The result in Revit does not seem to correlate with the value that our calculator generates.
I have checked through the conductivity values for the materials (under thermal properties) - and using the exact same values the Revit generated figure is far more optimistic.
For a typical cavity wall construction:
Brick (102mm) @ 0.54 W/mK
Cavity/air gap (40mm)
Insulation (60mm) @ 0.020 W/mK
Block CME (100mm) @ 0.51 W/mK
Plaster (12..5mm) @ 0.51 W/mK
The value that appears in the Wall Properties Dialogue box (greyed out - so I assume it is a calculated value) is 0.1935 W/m2K
Our BRE calculation generates a figure of 0.268 W/m2K.
The insulation manufacturer claims around 0.25 W/m2K for the given wall build up.
how we could have such a discrepency ? All the conductivity values are correct for the materials used in the wall build up.
I am beginning to wonder whethe the value in the Wall Type isn't a U-Value, although the units are consistent with it (W/m2K)
Material takeoff: As paint and other related calculations
I’m wondering why no values where calculated for the field “Material: as paint”! As for the “area” and “volume” calculation, they sound to be false, for example, the area of plaster board should be 0.02*1.84 but not 0.32*1.84! What might be false there?

Rebuild doesn't force recalculation.
There is an iLogic rule in the part, but this also fails to force recalculation:
iLogicVb.UpdateWhenDone=True
InventorVb.DocumentUpdate()
ThisDoc.Document.Rebuild2
ThisDoc.Document.Update2
Manual work around is to change the formula, then the value is recalculated.
iLogic work around is to change a parameter-value - and run the rule TWICE.
Question: How do I force a real rebuild, that actually wil recalculate parameter-values the first time I run the iLogic rule?
Background: The attached file is a little subset of the skeleton in a large assembly that is controlled by iLogic. The rules are placed in the topassembly, and writes vaules to the skeleton-file.
After writing values to skeleton-parameters I try to force them through with this iLogic
RuleParametersOutput()
InventorVb.DocumentUpdate()
iLogicVb.RunRule("Skeleton", "Update")
Later in the process I use calculated values to decide which components should be active. But my logic fails because my decisions are made on faulty values.
I did manage to get the updating work in 2011. But after migrating to 2012, it seems impossible to have it update correct. The user has to run rules several times, and doing manually updates to get a correct model.
When i use Get Data node in ICE for get Object Velocity, it not calculated. In help specified that velocity calculation is automatic for ICE. With velocity calculation turned on in object properties on tab Global Transform - only acceleration is computed, velocity is zero.

How is width and height calculated in the transform panel for an object? Does it use an average? An example can be seen in the first image. The lines are not a uniformed width.
Also, how are strokes converted from pts to pxls? For instance, if I make a stroke that is 2.3 pt, when I expand the object the width in the transform panel will say 2.3px ; however, I thought the point to pixel conversion (even for a 72 dpi screen resolution) was different. An example can be seen in the last two images, where a line was made with a specified stroke width and then expanded.
Any way to, have a source color chart, a target color chart, calculate what are the variations between them, and then use that to apply it to another image? I'm not talking about "match color", I know how that works, but is not what I'm looking for. It can be compared to switching to a custom color profile (calculated by the variation of source and target). Or something like "color lookup" (but with a custom icc/icm/lut). Creating a custom icc has been really complicated for me, and I still can't get it to work. (I have the icc profile, but can't open it nor from "convert profile" nor from "color lookup").

Currently, when I do drawings, I give my machinists drawings with each point, and they program their machines. To do that, they calculate the round part diameters, which is basically 5" - 2x<Dim>.

Is there a way with JavaScript to place an image with a calculated path and file name? I have 30+ artboards per document, each artboard named by product number. The actual file name of the master AI file is also already established (meaning every document I use this new script on will have already been saved).
Here's the scenario I'm hoping to create in the context of the documents mentioned above:
Run a script to "Place" a linked image based on the following calculated path:
["S:SAPCurrent Images in SAPStock Schools"] + [current ai filename minus the .ai extension]+[a hyphen like this "-"]+[currently selected artboard name]+[".jpg"]
This image link can be placed on a new top layer called "Images" or if necessary on the currently selected layer. Dimensions of the placed image should be a pre-determined size 8"x8".
Error if the ai document has not been saved yet.
