I 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.
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 Replies View RelatedWe 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?
why my existing walls show up fine in my sheet but don't plot to .pdf. I have the view range settings set correctly and all other sheets plot fine.
I thought maybe the roof transparency was the issue but Revit is usually pretty much a WYSIWYG plotting operation and the walls are displaying in the sheet file. Haven't tried plotting to a plotter but it doesn't matter. I need to plot .pdf's.
I use a raster image (JPG) on my title block for the Company Logo. This all worked fine in Revit 2009. Since I installed 2010 the logo no longer prints. I have tried other images and even converted it to a TIF.
It does not seem to be linked to any one printer. I have tried plotting on a HP Plotter, HP Laser Jet, Sharp Printer/ Copier, and even to a PDF. All have the same result. No Logo.
I have one drawing per file at model tab. When I need to plot a multiple page file, I use:
Print > Batch Plot.
The problem is that I have to set plot configurations ( plot style table, plot area, paper size, etc) in each file before use Batch Plot.
Now I received 722 files with a wrong Plot Style Table. For this time I change the associated *.ctb file at Plot Style folder, but I will need to associate the right *.ctb to each drawing. It's also common to have to change other properties.
Im trying to print my drawing A3 but when i shrink the page outline to suit, the print area is still A1. My original page size was A1.

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.

It says it is calculated using negative integral, however i dont find this very informative.

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.
I am a Mac user and new to AutoCAD. I am enrolled in a CAD class this semester and the instructor for my session is requiring Windows. Supposedly this is because AutoCAD for Mac does not allow for proper printing on their plot style setting.
I understand that I can install Bootcamp and Windows on my computer, but I'd really like to avoid that if I can. If I were to do my work on my Mac and then digitally transfer my files to a PC for printing purposes, would my files become corrupted or compromised in any way?
Where else do they keep this setting? I only have found it in Active Layout in extended dada
(entget (vlax-vla-object->ename(vla-get-activelayout (vla-get-activedocument(vlax-get-acad-object)))) '("*"))
The last pice of extended data is:
("PLOTTRANSPARENCY" (1071 . 0))
When i change it to 1
(setq layout(vla-get-activelayout (vla-get-activedocument(vlax-get-acad-object))))
(vla-getXdata layout "PLOTTRANSPARENCY" 'type 'data)
(vlax-safearray-fill data '("PLOTTRANSPARENCY" 1))
(vla-setXdata layout type data)
it stays there (extended data), but the setting in Plot dialog box doesn't change!!! And it still prints no transparency.
It takes to save the drawing and reopen it again to see the change.
The command -PLOT does not have this setting as well, so my options back to VBA or Lisp, but HOW?
I have a problem to plot thin lines and dots when Plot Transparency option is On in the Plot dialog box.
The lineweight is a half of the original. I think i have tried everything.
It shows correctly in the Plot Preview but when printed there are no dotted hatches and lines are much thinner.
