I'm testing out a simple Block Table in the Dynamic Block editor and when I go to save the Block, the following alert pops up. Is there a way to "test" the Block to check all the necessary constraints? Or am I just suppose to go about this with good 'ol fashioned trial and error? Seems the block is working just fine so is the alert just a moot point?

I am in the process of fixing one of our dynamic blocks. It's a fairly simple fix where there was a typo in one of the names of our items in the lookup that needed to be fixed.
I changed the name of the item in the lookup table. I went and did the test block and it seemed to work fine, but when I bring the block into a drawing, it reverts back to the old lookup as if I did nothing at all.
I made sure that the path was correct and I even just dragged and dropped straight from Windows Explorer to no avail.Does AutoCAD keep referring to the old block? Did I forget to change something else?
My boss gave me a copy of Autocad 2012. I've messed around with architecture 2010 before so the ribbons are no surprise. One thing I have noticed that's really different is the dynamic block constraints & block table actionblock properties table? I looks very similar to the lookup property table
View 0 Replies View RelatedSo I'm creating a block with a block table and constraints. The constraints such as Geometric Constraints work just as assumed. When adding in dimensional constraints we start to have more fun. So I have dimensional constraints that use other dimensional constraints to manipulate itself.
EX. dimconC = (dimconB-dimconA)
dimconA is 12
dimconB is 14
dimconC would be 2
Now when ever dimconA or dimconB change dimconC would populate accordingly.
With this I wanted to make an attribute that could be placed in instead of a dimensional constant.
EX dimconC = ((Att1*dimconB)-dimconA)
Att1 is 02
dimconA is 12
dimconB is 14
dimconC would be 16
However when trying to place in formula that references a attribute I keep getting an error "A DEPENDENT EXPRESSION CANNOT BE EVALUATED" So I assumed it was missing an expression from the attribute, however once entering an expression in for it I still get the same error.

Is this something that is not allowed at all or have I over looked something?
Is it any option to keep text righ-reading even if block is rotated (by AutoCAD command ROTATE, not dynamic action)?
View 9 Replies View RelatedI have created a dynamic block which has hatchings in it.
In the block editor when I do a test of the block everyhting runs smoothly.
Howevfer when it is in model space it fails to keep the hatch boundary associativity. Even when the same dimensions are used as the block has as default.
Why would this be?
The attached image shows a block of a speed ramp. I have a linear parameter in the middle of the block to stretch the block. When I stretch the block I want the triangles to be evenly spaced. I have setup constraints as shown. They are all linked back to d6 but d6 is locked. How do I unlock it so that it changes and the dims update?

Is there a Geometric Constraint that can keep the two lines (red and green) keep touching the blue one and look like the drawing right below the block that is Exploded?
is there a way to make a dynamic block that adapt when using with constrait...i want the block, wich will be a panel with different visibility, to adapt between 2 geometry using coincidence or colinar constraints
so when i change the parameter of the distance between the 2 geometry , the block length will ajust accordingly i'm not new to the dynamic block but to using parameters with it, never done that.
select all blocks on certain layers in a drawing, check attribute CIRCUIT in each block if it starts with MS then attribute CONTROL = switched. I hope thats clear enough the way

Is there a way to add a hatch to a block definition without losing the constraint points ? Once I redefine a block with a hatch I lose the ability to use any parametric constraints with the block. interestingly, the block reference already in use don't lose their parametric constraints.

I am trying to create a dynamic block that represents a cable with an attribute attached. The block is essentially a line that runs along the Y axis. I have created a distance parameter with a stretch action attached. The line is to remain anchored at the top and the bottom end is permitted to stretch.
Problem: I have an attribute inserted to the left side of the line (offset at -2mm TC insertion) at a rotation angle of 270. When I select the stretch grip (in the drawing environment) I would like the attribute to remain centered with the line maintain the offset and maintaining the rotation angle. I have exhausted all of my options (limited experience).
I am using Civil3D 2012 SP 2.
I am creating a block for my details. I want to be able to title my block and the the line under my txt will change it's length based on the lenght of the text. I keep playing with the constraints, but I haven't found one that is doing what I want.

I have two dynamic blocks. One is the plan view of a cylinder and one is the elevation view of a cylinder. When I change the parameter of the OD on the elevation, I want the plan view to change. I'd like to keep them as blocks (they're a little more complicated than just cylinders), but when I try to use parametrics to tie these two dimensions together I get: "Constraints cannot be applied between nested objects in the same block or Xref."

Is it possible for AutoCAD to check the spelling of an attribute within a block and confirm if it matches a word in a list of names in an excel file or table in another AutoCAD file?
This is required because the attribute then gets exported to be inserted into another database program and the spelling has to be exact otherwise it will error. The list of names to check are colours and there are approx. 100 of them.
What would be perfect is if the attribute is a drop down list which is a live list of the colours in the excel file, but I dont think this is possible?
I have a VBA code for check and choose unit but how i can in .NET ?
Unite = ThisDrawing.GetVariable("INSUNITS") Select Case Unite Case 4: Unite = 10 'mm Case 5: Unite = 1 'cm Case 6: Unite = 0.01 'm Case Else: Unite = 1 End Select
db.UnitMode is always = 0
i have try this :
Dim BlocT As BlockTable Dim tr As Transaction = db.TransactionManager.StartTransaction BlocT = tr.GetObject(db.BlockTableId, OpenMode.ForRead) Dim Bloc As BlockTableRecord Bloc = tr.GetObject(BlocT(BlockTableRecord.ModelSpace), OpenMode.ForRead) Dim lay As Layout = tr.GetObject(Bloc.LayoutId, OpenMode.ForRead) tr.Commit() tr.Dispose()
but bloc.units dont egal the unit command in autocad.
I can use :
Dim obj As Object = Application.GetSystemVariable("INSUNITS")
but i want a proper solution with .net.
I need to drive more than one constraint at a time. The assembly consist of a hydraulic ram that pulls a cable which is routed around a few pullys and then pulls another linear moving member. I don't really care about modeling the cable right now, I just want the cylinder piston and the final member to move in unison. I can only drive one constraint at a time, so I figured I could relate the two constraints together by setting them equal to a parameter (variable), but that isn't working. Is it me or is driving multiple constraints at a time something that would be very useful for a lot of applications?
View 3 Replies View RelatedI'm modeling cables running through a series of cable clamps. I'm working in an assembly with my structure as one part, clamps as seperate parts, and cables as separate parts. I modeled the clamps first and am using them to create my 3d spline to run the sweep. The clamps have moved several times and each time, the sweeps (cables) do not update to follow the new clamping path. I have tried multiple ways of solving this.
I've tried to redo the splines using "Include Geometry" and running the spline through the centers of the clamps. I've also deleted the constraints (which for some reason turn into fixed) and reapplied them as coincident constraints. However, once I setup these coincidences, they always change back to fixed.
In a last ditch method, I've created 2d sketches at EVERY clamping location (yes that's alot of sketches, time and effort) and projected the circular geometry to get a center point. This has seemed to work, but is so much work, there's no way we could use it regularly.

I normally get the UCS directions as part of a test to see if current coord system is same as world:
I am seeing a nonnormal UCSxdir and Ydir for several drawings with UCS I know is on world. See the above value.
It took me a while to realize it was because the drawing had ps viewports, and the viewport UCS was user.
How would I get what I would call "the modelspace current coord system info" to do this test.
I am doing this with a drawing not open in the editor, it is DBX style. If it was not, I could do all kinds of things to figure out if modelspace was on world ucs.

Is there a way to simulate a simple tensile test in autodesk inventor. Let's say I draft up a 1" x 1" x 10" bar. If I input all of the material properties such as yield strength, tensile strength, % elongation etc., is there a way that I can simulate a simple uniaxial tension test on this bar? If so, how do I set it up with the autodesk simulation engine?

How would I test for duplicate handles in a file. If I select a cirlce from an xref and it has a handle of "E6" Then I select another circle from a different xref that has the same handle. When I use GetObjectId how do I specify which handle? Is there a way to give a handle and a file path and have it point to the correct entity or would I need to cycle through all entities and check for matching handle and file name?
In the end I would like to select an object, then store that data in a file and then recall that exact same object later.

Im trying to write a routine in VB.net based on Fenton's examples from 'Zero to 3D in 60 Minutes'. the routine uses a filter set to select all 2D polylines in a document then a test is needed for each polyline to establish whether it is a loop, which can then be extruded into a solid or it is a non loop, where the operation will need to be an extruded surface, or if the polyline is a non-loop.
So far my code will pick up every 2D polyline and try and extrude it, but i need to catch the non-looped entities to handle them with an extrude surface method or if self-intersecting polylines, to either drop them and not cause an exception or process them in another way.
What entity attributes or methods should I use to perform testing to establish this loop and non-loop existance of the polylines to achieve this. I work with both C# and VB.net.
