How R is calculated in the C3D?
I’m wondering regarding the equation used to calculate the radius of the circular curve. Is it the one attached? How the horizontal curve is updated as the design speed is changed?Ja

Any hydraflow calculates depth of flow and spread at sump inlets? Does it assume that the entire flow is coming from one direction (similar to an on-grade inlet)? Or does it make an assumption about how much flow is coming into both ends of the inlet?

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.
Is there any command that the calculated area may appear on the drawing?

How are arrowhead attachment locations calculated when using the Automatic Balloon command? Arrowheads seem to attached to objects at rather strange places!

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>.
I'd like it if I could give them drawings with the real number, and in parenthesis next to it, 5-2x<Dim>.
I've attached a jpg of what I normally give them and how I'd like it to look. Is this something do-able via a macro or something?

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)

View 2 Replies View RelatedHow 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").

I imported Google earth surface (at eye alt 600m) to civil 3d 2012 and created an alignment of length 181m.

I want to create a Layer Filter that excludes both Civil Layers and Xrefs.
I have created one that excludes Civil objects (Excel Civil.jpg) but when I add a filter for excluding xrefs as well the Civil objects appear in the filter again indeed all the layers are included again (Excel Xref.jpg) if I invert the filter nothing is displayed.
Is it possible to export created surface from civil to revit architecture? If yes , How? And if its not possible - maybe i can somehow import cogo points to revit?
View 6 Replies View RelatedI am trying to work on a previous file in my office, and when it opens on mycomputer, it does not display as it should.
In general, the purpose of the project is to reinstate the side slopes of a road abutting a river. Cut & fill sections have been generated on 20m station increments along the road corridor/surfaces in order to calulate cut and fill as well as to reference the design to flood levels.
When I open the file, all of these sections (and there are alot) have relocated themselves to various locations in model space, none of which are aligned with the viewports that are being used for printing.
Could it be software and/or hardware incompatibility with the computer they were originally created on? (I believe it was created with C3D 2010, or C3D 2011 - I am currently running 2012)
Just curious as to whether people use much colour in their production drawings, particularly for hatches...?
Working for Local Government, we tend to utilise colour hatches to show all kinds of information.
Generally, we have found that colour hatches are a good way to clearly show different areas and materials such as pavements, paths, landscape areas etc. Hatches can then be used to quickly ascertain areas for estimation and our construction team like them too as the plans tend to be easier to read.
The usual arguments about reproduction of plans and slowing down of computers doesn't seem to be an issue for us. Most photocopiers are in colour now anyway and we just make sure that even in black & white the plans are readable.
The way that Civil 3D deals with hatching doesn't seem to slow things down for us either.
Currently using Civil 3D 2013 & 2014 SP1
Right now, the only way I know of being able to see Civil grading objects (surface contours, spot elevations, slopes, etc) while using plain vanilla AutoCAD is to explode everything and export to a lower version.
I'm trying out a trial of AutoCAD 2013 to test things, and my Civil drawing shows up as boxes/text when xrefed into another drawing without doing the task above.
I'm looking for a more efficient way to see grading using AutoCAD (not Civil). Civil is expensive, and I'd like to downgrade the drafters who don't know how to use the Civil functions (and never will), but still need grading to show as a dynamic xref in the background of the drawings they're working on. Problem is, if I have to explode and export my drawing every time I want to update the grading xref in their drawing, it wastes more time than I'd like.
Is this the only way and I have to live with it, or am is there an easier way that I haven't dug up yet? I know I'm not an expert at Civil, so I may be going about this all wrong.
Is there a way to search for a text style in a civil style? I have a text style that our company is trying to get rid of and I would very much like to not have to go through our 72 company styles.

I've begun creating my drawing template with all my layers and each layer has a plot style attached to it. The line weight is set to default. I am doing a test plot with a drawing that I have to see what it looks like. The pen table is set to my .stb table but when I go to preview, my linework doesn't show up.
I have checked my setting for my layers to make sure that they are set to plot.
In my plot dialog box, if I uncheck "Plot with plot styles" I can see the linework but it doesn't plot right (plots in color). Unchecking "plot object lineweights" doesn't do anything either. What am I missing?
