AutoCad 3D :: Spiral Stairs Hand Rail Heavy Model
May 13, 2012
NO, I don't have any problem with making a helical hand rail along the circumference of a spiral stairway (or helical stair stringer)!
My only problem is that the method which gives the best visual results (viz. extrude or sweep circle or region along spline) will give a "HEAVY" solid model that HINDERS the performance of AUTOCAD.
Therefore I mostly use the extrusion along a 3D-polyline that gives a a lighter model but less nice visual results (especially when using flatshot for 2D model "representation").
Can I set some system parameters that increase the performance when extrude or sweep along a spline ?
Standard I use a lot of blocks to increase the 3D perfomance of AUTOCAD, this however is not possible when a visual continuous hand rail is preferred.

We have a project that has been upgraded to Revit 2013. When creating railings using the new railing types, top rails and hand rails disappear/are not visible seemingly at random. For instance, when a railing is created that contains railing profiles in the non-continous rails dialog box in addition to a top rail, the top rail and extensions are not visible in plan, but the rails created in the old non-continous dialog are visible.
This seems to occur only in our upgraded file. New projects seem to display the top rails and hand rails consistently.
Also, with railings that contain a "Wall" type extension, the extension return occurs at a 90 degree angle even if it is set to have a fillet. Further, in some instances, regardless of whether the rail is flat or sloped, the end wall extension return will display as two separate rectangles overlapping (i.e. it looks "broken"), instead of a clean, continuous railing. This seems related to the "direction" that the rail sketch line is drawn (a line drawn from the bottom of the screen to the top will have a broken railing, one drawn from the top of the screen to the bottom will not).
I know that scolding the Autodesk software developers isn't going to change anything, but I feel the need to blow off a little steam. The railing and stair "improvements" for this release are really not worth much. It's still much more time consuming (and frustrating) to model these elements, and with poorer results graphically, than it is to simply draw them. It's still not possible to dimension them properly, place balusters where you want them, make multi-level stair towers join properly, get the up/down arrows to display correctly, and a host of other issues. It's incredibly frustrating and baffling that there are so many issues with such a core component of the software's functionality.

I have tried to rotate this railing in 3D so that it looks like this photo but I can't. I've tried several different things with the UCS but clearly I don't know what I'm doing. So I'm turning to the CAD community that does. I can draw the hand rail no problem. But the drawing always leaves the finished hand rail in the X,Y plane. I need to rotate it in the Z axis (I think). Here is the orientation I want the railing to look once it's drawn. I need a step by step procedure so I can learn how to do this the correct way for future reference.

All lines in model space appear thicker when I zoom in.
how to change this behaviour so they show the same weight thin in the computer window?

Is it possible to define custom Rail Types in Rail Track Layout Utility for AutoCAD® Civil 3D® 2013?
There is only combobox with predefined Rail types 49, 54, 60.
I found: "The rail type defines the standard turnout types (e.g. 49, 54, 60 etc.)or other user defined types "
, also there is mentioned, that "...pre-prepared turnout types that are written in the XML file ara_switch.xml"
I can't find that ara_switch.xml file.

I am trying to modify a figure that was made in Inventor; I want to be able to move the limbs around and not end up with any un-natural looking poses. I'm starting with the hand/fingers, and not having much luck. It should be as simple as picking the axes of the different digits of the finger, and telling Inventor to use angular constraints, but I still keep getting painful-looking bends. Sometimes it appears to work, but by dragging the digits too far on the screen, then blow past the defined constraints.
Is what I'm looking to do not really going to work here? I can't do this with Bones in MAX; I need to be able to re-size this figure parametrically, and that can't be done in MAX where everything is a mesh.

I have a modeled right hand part and a detail drawing of that right hand part with a pin that defines r.h from l.h. and I would like to save them as a left hand part then change the model by reversing the pin. How would I proceed with this task?

I am running two networked computers and a networked Designjet 510 plotter. One computer runs LT2013 and the other LT2014.
I am having an issue with the LT2013 machine in that it plots much darker than it should (uses a heavier lineweight). I have checked the plotter set up and plot style and both appear the same.

How can you balance a heavy auger?
It can vary from 8ft to 12ft long 24inch diameter 3/8 to 3/4 inch flighting.
No problem doing a static balance but when it is rotating its off balance end to end and shakes the equipment its on.
Not only is it hard to figue out how much weight to add but at what l degrees.
I do know the weight has to go on the ends .It there a way of getting it close with the simulator and if it is how do I go about it?

I am finding that my DWF files sent to the plotter are plotting with the linework being heavier than the same file sent directly to our plotter. These are just lines that should plot with a narrow width (ie walls on a floor plan) but they seem to be about twice the width and hence look "darker". Is there a setting that I am missing or some other way to get the lines to plot out thinner? Also, TTF fonts plot thicker in DWF. I've tried the various options in the DWF viewer when sending to the plotter, but none seem to work.

I have a drawing with several views from the VIEWBASE command that turned out great. I ended up having to use a viewport for one of my views because certain features wouldn't show in a base view. The problem is, the lineweight of the viewport looks quite a bit heavier and more pixelated than the base views. I tried it with my own plotstyle and several of the generic autocad ones.
How can I make the viewport look as crisp and clean as everything else?
I've attached a screenshot for reference.

Sometimes I get xrefs that just seem to drag the system down - also on high end systems. This especially happens if I start throwing the view-cube around. Have you got any tricks on how to make such xrefs more "easy" on the system?

We have all of our job files stored on our network. If you open a sheetset from one of those network folders, it will open normally, you can view and scroll thru it normally, but the second you select / right click anything, it locks up cad (grey screen) and shows us the hourglass for 3-6 minutes, and then allows you to work with it, but with a 10-20 second delay on anything you try to do. If you copy the same job folder to the C Drive, and re-open the sheetset, it operates perfectly. Running a constant ping to our server returns a <0ms return with no lost packets.

am using Inventor 2012. Is there any way to select two rails when sweeping? One for the x and one for the y. I can only select one rail. If I choose Profile Scaling X & Y, it does not sweep the way I want to.

We are developing an equation driven 3d spline using VBA.
It generates a 3D spline, guide rail, and tool profile, but we're having trouble figuring out how to do the actual "sweep with guide rail" using the API.
Attached is an .ipt of the shapes our program is generating automatically. The problem is we are having to manually create the sweep after the geometry is created.
How can we automate the sweep with guide rail process?

I am using civil 3d 2012 and i want to use rail assembly for my single track rail project. i want to know how can i customize my assembly. As in given defaulf assembly i can keep the width of sub base same on both side of track centerline. But my requirement is to use different widths on left and right side of centerline of track.

I'm trying to produce this loft but the rail I really need it to follow won't produce any results. The other ones on the 3d sketch will work just fine but not the regular sketched one. It seemed to work when I made the rail a straight line but I need it to follow the edge of the surface which is a line, tangent to small r3 arc, tangent to line and connected through projective geometry from the original surface sketch.

I work in Rail Development and I am trying to create an assembly that will automatically generate a rail/tie shape and label Top of Rail Elevations, Track name and number, and offset distance. I have been copying/pasting a block onto each track in every cross section. This takes way too long! I have attached an image of what I want the assembly to look like in the cross section.
Before now, I have been typing in all of that information, when there are 9 tracks and 77 cross sections.

So, In this drawing, I have 2 blocks. Stair, and stair section. The one I'm working on is stair section.
What I have is the base of a block that will automatically add steps to the desired height, at a 7" rise and 8" run. I have the array function working correctly. It is inserting correctly, etc.
What I'd like to do is to be able to stretch the frame by typing in the final height of the stairs, and have the length and treads adjust as needed. I'm sure that there is something in the xy parameter actions that I can use for this, I just don't know what it is.

Any good example of ILogic in creating stairs? We generate many different widths, lengths and heights? Been trying to utilize iLogic to make all the different types more easy to create from the start. Have set angle of stringers and certain widths of treads but cannot figure out my rules on the number of treads needed per the length of my always changing stringer lengths. Stumped on how to take a certain length (parameter) and divide it up equally. Top tread flush with top of horizontal stringer and with bottom tread having a minimum and or maximum height the from floor.

I edit Sweep1, select path with guide rail, try to select the curve in 3D sketch 2, but don't succeed.
First, it selects both, the path and the guide rail, and when it offers me to select the path alone, i don't know how to call it in english, again it gives a warning.

I'm trying to apply the right constraint in stress analysis environment.
How would I apply the right constraint? And to which face of the wheel or axle should I apply the constraint to get right results.
If I'm applying the sliding connection to the face of the wheel in z direction, the model will stop stress analysis with an error of "not enough constraints"
if I apply the sliding constraint to the inside of the wheel on the surface of the circle, I get the result as attached. I get 0 reaction in the Z direction which is wrong and should be zero reaction in x direction. How do I get it right?
The correct way to me would be a constraint that would only take forces in the -Y direction, same direction as gravity.
The wheel should not have any other reaction than in the Y direction. Hoe do I define that constraint? In my model the wheel are free to rotate on the axle.
I'm attaching both the general arrangement and the reaction report.

I have created an elevation of a railing with stretch and array actions, however I have not been able to figure out how to center the array'd picket on the top rail. I've added a move action to the main picket in order to manually center after the railing has been stretched between the two posts...however I'd love to have this automatically centered.
(I originally thought I could have the main picket stretch at 0.5 (so it would be centered), then array in two directions, however there is no angle option on an array paramater).

I am trying to model a forged steel table base so I can create some tooling to reproduce it. See the attached photo of the base. I am able to sweep along my 3D projected sketch path but there is a twist at the center that I believe I need a guide rail to control. I have tried to draw a rail but it fails.
I suspect I am not drawing my guide rail correctly as to create the slight twist. I was considering drawing a shallow helix along the 3d sweep path but not sure that this is the best direction to head next. I have attached the .ipt with the sweep (without guide path being used).

The wheels on the side need to roll inside the guide rail. I can let them roll in each part separately but not in the entire rail.
I already tried with transitional constrains but then inventor says that there are some problems.My project needs to become a sectional gate so there's going te be lots more than just 2 wheels in it..

I wonder how do you create a concrete construction under the stairs?
The way ACA creates stairs looks like just a top layer (tiles or wood panels), but I want to put those tiles on a concrete construction.
