i want to create a sketch line for a sweep where the radius of the curve varies.. i don't want to use a spline or piece together arcs.. something about distance and radius along the line.. is there a formula and can this be done in revit?

Trying to apply a variable radius to a part. The direction of the radius is wrong (pointed back in toward the part) and I cant get it to go the other way. As long as all the fillets along the curve are the same radius, the fillet will compute, but if I make them vary, then it fails.

so my first question to you good peeps: i've been trying to "bend" text to follow a radius using 'fit to curve' ... this has been problematic as the text wants to align itself at the end of the curve rather than the middle.
is there another way to bend text to a specified radius?

We have a family that errors when certain values are hit. Its realated to Automatic Sketch Dimension reassociating with work planes when two workplans over lap... Anyway, the QA team knows about this.
The problem I have is that I have an IF statement to trigger an generic error message when these two rare conditions are met. I would rather a pop up window explaining what thy can not do. "Position of legs from ends can not equal half total length" and an OK button.
Is there a "say" style command for revit formulas?
I'm facing a problem dealing with visibility formulas... My situation that im dealing with is, I have 2 yes/no visibility parameters, one that is called Right side clearance and another one named Left side clearance. I want to create another yes/no visibility parameter that's called Clearance. I want to link the Right and Left clearance parameter to the Clearance parameter where if it is off, then there will be nothing that shows.. But if I want it on then I would have to select either right or left without them both showing up?

The association between design speed (V) and radius of circular curve (R),
As the R is positively related to V according to the equation (attached), then I expect that the C3D changes R value as the value of V is changed.
For example, on the attached screenshots, the R value of horizontal alignment is built based on a design speed of 100km/hr. Now if the speed is changed to 50km/hr, then why the value of R is not automatically changed to be compatible with the new speed?
I'm trying to use a formula in a family that requires the host wall thickness.
I've setup an instance reporting parameter (dimensioned to the host wall faces) - which works fine in reporting the correct value.
But when I try to use that variable in a formula, I keep getting the error:
"Instance Parameters can't be used in Type Parameter formulas."
Is there a way of getting the reported dimension as a Type rather than an Instance - or is there another work around ?
it is possible to create text and then attach a formula to it to change it.
For example:I want to be able to draw or pick a line and if the line is less than X ft than "Say this" if the line is greater than X ft than "Say that"
I wish to create a formula for a family parameter which itself references a 'Type' of an imported family. Specifically I wish to create a quoin stack which can be used for a 'reveal' situation either side of a door or window rather than just on a corner. A 'quoin stack,' as that which comes with the revit content files, typically is made up of two vertical arrays which intersect giving alternative long and short sides. Each of the arrays is made up of a different quoin type, a 'Short' and a 'Long' type which swap dimensions from from perpendicular face to the other. This of course is no good for a reveal situation where on the window or door reveal of both interleived courses needs to be the same, whilst maintaining the 'long/short' appearance on the wall face containing the window or door.
I have got so far as to create a 'reveal depth' parameter within the quoin stack family but need to find a way of addressing the 'Long' quoin type to change its 'short' dimension to suit the reveal depth whilst changing the 'long' dimension of the 'Short' quoin type to be the same.
is it possible (Revit 2014) to set up alternate dimensions that report the value represented in a different way via a simple formula?
I am trying to show my dims as brick units (based on standard metric bricks 215x102.5x65mm with 10mm mortar joint), and was hoping to create new 3 dim types, based on CO+, CO- and CO, so the alternate dims i want would be:
CO+ =[value-10]/225CO- =[value+10]/225CO simply =[value/225]
with the appropriate suffixes (CO+, CO- and CO). If this is possible..... or on the cards?
You can create a variable pitch helix by using the Equation Curve feature introduced in Inventor 2013.
Create a new 3D Sketch. Start the Equation Curve command.
Here are equations that I use to create helical curves. Many other variations exist.
Cartesian coordinates:
x(t) = radius * sin(360 * num_turns * t)
y(t) = radius * cos(360 * num_turns * t)
z(t) = height * t
[Code]....
When you sweep a profile along a helical path, use the plane normal sweep (instead of perpendicular sweep) to orient profiles suitable for coil or spring. In the example below, the sweep path is a constant radius, variable pitch helix.
is there a way to make a if and conditional statement formula in a family with 3 tests?
For example,
Behind Furniture, Biscuit, Masonry Wall, Hard Ceiling are all yes/no parameters
if(and(Behind Furniture, Biscuit, Hard Ceiling), 0' 0 5/16", if(Behind Furniture, 0' 0 11/64", if(Biscuit, 0' 0 11/64", 0' 0 27/256", if(Masonry Wall, 0' 0 11/64", 0' 0 27/256"))))
what is wrond with my formula?
I am trying to change a dimension based on what yes/no parameters are checked. It keeps telling me that its "a bad if statement format". It works fine for the first teo dimension tests but when I add this last one I get the error. I need the 3rd dimension to check against 3 yes/no parameters all being = yes before moving on to the next check.
I'm modeling un hold house and one of the exterior walls have variable thickness.
I don´t need two walls with different thicknesses but just one that is changing is own thickness along his development.
how to create a floor or structural slab that is both sloped AND has a variable thickness?
I can do either, but not both. Thinking that I may need to create a generic mass.
I have a highrise that steps inward in various areas. Since I model structural concrete, there are no window walls stopping my depth of view.
Is there an option where I can vary my depth in areas? I don't want to create more views. An option is to halftone the areas that are set and hide walls that are way in the interior, but this is very time consuming. In addition, if I halftone a slab, the slab portions that are not inset turn halftone too, then I have to fix the linework.

Is there a better way of achieving this (screen snip attached). To get the roof segments off lower plate heights I have added in temporary walls corresponding the higher plate height, picked by footprint then extended the overhang on these segments to hit the lower plate height. Then erase the temporary walls. But this detaches the edit footprint-edit overhang function.
Is there a better way? If only a line element would host a roof to enable slope and overhang association.
I developed a handrail extension that turns down and terminates on top of the stringer and I'm having some trouble controlling the "bend" to get a smooth arc for all angles. Is there away of aligning or constrining the arc in the sweep path to achieve this?

I created a curtain panel family and loaded it into my project where I had created a mass and divided the surface, and changed the panels to be my curtain panel family i created. The mass has a curve that I want the panel to be on the inside of, but the panel is always placed on the outside. File is attached. So on the smaller curve on the north side of my building, the panels are placed on the inside of the building instead of the outside. How can I place the panels on the outside of the building along the curve?

I'm attempting to write a batch script to add some layers to a pre-existing image and save a copy. I've gone through the tutorial, and have run the demo code from Basic_Batch with no errors, but my (what I think of as simple) script throws an "Error: eval: unbound variable: ?" It also seems to cascade the error to other scripts, as I then get "unmatched parentheses: 2" errors from what I assume to be the script immediately following my own during Script-Fu load. This occurs whether running from batch or clicking "Refresh Scripts" from the Script-Fu menu.
What I could find on this forum and Google suggests that I may be required to 'define' one or more of my variables before using it, but for the life of me, I can't figure out which one that would be, and the error (reporting that '?' is undefined!?) I've quintuply (probably more ~_^) checked my parenthesis matching, but they look fine to me.
In case this was an encoding issue, I've tried saving my .scm file as both UTF-8 and ANSI. I should also note that I'm running Windows 7 x64 in English-US.
Script:
(define (script-fu-build-imagebasefilemytext)(let*((image (car (gimp-file-load RUN-NONINTERACTIVE basefile basefile)))(drawable (car (gimp-image-get-active-layer image)))(title (car (gimp-text-layer-new image mytext "Courier" 18 UNIT-POINT))))(gimp-image-add-layer image title -1)(gimp-image-clean-all image)(gimp-file-save RUN-NONINTERACTIVE image drawable "K:\\Images\\Temp.gif" "Temp.gif")));
Since I intend for this script to only be run from batch, I haven't bothered including the typical register stuff.
I want to draw hyperbola curve whose equation is x^2/a^2 - y^2/b^2=1. May I use equation curve tool to make the above hyperbola.
I have also made a hyperbola curve of aforesaid equation through conventional method on mathematical ground in the past.
I have ran an analysis and SSA gave me Error 607 on the report. It says "Inlet A9 gutter capture curve is not a valid curve."
A couple things I did different from the video lectures...
I selected user define for the Tc to figure out Q. i computed those manually.
For the Inlets I have selected Maximum Capture Cutoff.
There are some inlets in this model I created that do not capture 100% of the flow so i created conveyance links to account for the bypass flow.Not sure why is not recognizing the Curve?
