I have used DXF files in the past for flat non-complicated cnc machining. I have a situation were we manufacture pipe and I would like to create the pipe in 3 dimensionally in AutoCAD and convert the dwg file to a dxf file for the steel cutting table. Will the DXF conversion convert the round cyclinder in CAD to a flat suface for cutting?
View 1 RepliesIs there an automatic way to force a mesurement, to become Referenced? (driven)?
Even if sketch is not yet totally constrained?
If I have a parameter in a sketch were I want to change side of the reference line in a other word I want to put in a negative value in the parameter to change side. I want to do this because I have used this parameter in other equations and want not delete it and replace again.
View 5 Replies View RelatedI want to creat a driven dimension that I can use as a reference dimension in another part. Is there an easy way to do this without creating a new sketch, going into a previous sketch, making a long function based on other dimensions, etc.? For instance, just like the measure tool, but it stores the measurement.
View 4 Replies View RelatedIf my memory serves correctly CATIA used to have a feature pattern type that allowed for the selection of two sketches (or something along these lines, my memory is fuzzy). One sketch contained the feature profile, and the other contained points where you wanted the patterned features to plop out at. Is there any similar function in IV?
In case there's another way to accomplish what I'm trying to do, I'm drawing a piece of roll formed sheetmetal with a crap load of slots with non-uniform spacing. I would really prefer to not have to create a sketch and draw all these slots. Especially when there's not even a legitimate slot command. I could probably draw one and then copy it around a bunch of times,
I would like a part, that if i place it into an assembly, that it asks for a parameter (for example the length).Parts in the content center have this featere (for example tubes). I think this has to do with the driven length in the content center.
How do i create a driven length?

View 3 Replies View RelatedI have an assembly I've put together in Inventor 2011. I tried to make an adaptive spring to use with a shock that goes in a car. I'd like the spring to change size as the shock extends and contracts.
I went through the process of creating an adaptive spring, and it worked, but I could only change the length of the spring by using the "Drive Constraint" feature, which only allows me to adjust the spring when I'm using the "Drive Constraint" menu. It plays like a movie. What I want is a part that just moves like you would expect when you push/pull the ends of the shock. I don't want to have to drive it like a movie.
So then I thought that I could just simulate a spring by making a series of rings (toroids). I could constrain the bottom ring and top ring to the shock geometry and then have the other rings position themselves according to the distance between the top and bottom rings.
SO, I have 5 rings. The bottom ring is grounded the top ring has a Limit Constraint that sets the top ring anywhere between 3 and 7 inches above the bottom ring.
How do I create a driven dimension on an assembly that will automatically update the distance between the top and bottom ring?
I would like to call that dimension "HEIGHT", and then I could use parameters to set the middle ring a distance (HEIGHT/2) above the bottom ring, I could set the ring below the middle to (HEIGHT/4), and I could set the ring above the middle to (HEIGHT*3/4).
I should then be able to move the upper ring up and down and the other rings reposition themselves automatically to keep even spacing between the rings on either side.
I tried making a sketch in the assembly and using the "Project Geometry" function to add the location of the upper and lower rings to the sketch. I then used the "Dimension" function to create a driven dimension between the upper and lower rings. When I finished the sketch the other rings all updated exactly as anticipated, but when I moved the top ring the projected outline did NOT move, so the other rings did not continue to update.
lease do NOT link me to adaptive coil video tutorials or explain how driven dimensions work when making parts. I am not looking for that, I am looking for how to create driven dimensions between two placed components in an ASSEMBLY.
Is there any way to pull text from a spreadsheet into arc-aligned text? Like if I were trying to make round inspection tags but didn't want to type in the inspection code each time, or if I needed to change something? Is it possible to put a field into the text to refer to a cell location in Excel?
I just started using AutoCAD 2011 (I was previously using AutoCAD 2005) and am having a hard time finding my old controls while learning all the new features for which I got the program.
I have been working with dynamic blocks lately and I am fascinated with the tool and its capabilities. However, something that I have not been able to figure out and not sure if its this is doable ---->
Can you make a dynamic block table driven, say from an excel table?
For example, lets say you have a dynamic block with parameters/actions set up that allow you to set the width, length, height, distance from edge, # of object arrays, etc. Rather than grabbing each grip and specifying the desired dimension, can you make it so the dynamic block is table driven? such as, where you might have a list of desired dimensions (say in excel) and you want to quickly input them into a table in autocad, so that the dynamic block will adjust to those dimensions?
I have a parent assembly that contains multiple sub assemblies, two of which need to synchronize with each other.In the parent assembly, I have created a user form that controls the sizes and quantities of all the different sub assemblies.
Sub assembly 1 contains a bracket for supporting 4 rows of pipes.Based on the width selected from the main parent assembly, the length of this bracket can vary.
The spacing of the 4 mounting positions is also determined from the length of the bracket.Sub assembly 2 is an assembly containing all the pipes.The pipes are spaced apart to suit the bracket using a component pattern, and it is this distance that I want to control from the parent assembly.This is just one of the basic scripts I've tried.
Pipe_Spacing=Parameter("SubAssembly1:1", "Pipe_Spacing_A")
Parameter("Piping assembly:1", "Pipe_Spacing_B")=Pipe_Spacing
Pipe_Spacing_A is the spacing of the bracket
Pipe_Spacing_B is the component pattern in the piping assembly
Pipe_Spacing is the parameter in the parent assembly to be driven by the bracket parameters.
I have very little iLogic experience & have being learning as I go along with this project.My best guess is that the code can't loop back on itself. On a slightly different note, I have also noticed that the sub assemblies don't update properly.
If I adjust the width to X and regenerate the model, some of the sub assembly updates. To fully update, I have to go back into the user form, change the size to Y & then change it back again to X and then regenerate.
In 2012 when in a sketch in an assembly all the stuff under "Format" is grayed out.
You cannot make a dimension driven, nor can you make a line construction or a centerline and you can't change a sketch point into a center point. Do I have some setting wrong?
I want to use I logic to adjust an assembly constraint based on T/F value passed from a master sketch.
I have passed the paramater T/F and/or a user paramater as described in this thread using link (neet trick).. but when the code fires it only works on the true application and not the false.. if i open the rule and then close it the update button becomes available and when updated the false condition updates sucessfully. I have tried just re-running the rule to no avail. It seams that the only way I can get it to triger a false condition is to open the rule... close it and update.

I am trying to record a video of a driven constraint. It seems to work fine until I go to view the video file. When I open the file the windows media player opens but no video plays. It acts as if the video is a ~ milli second long.
I have tried to save the file in both formats: .wmv and .avi. Both do the same thing.
I am in the process of compiling a parameter driven sprocket. I just download the model from the CBLISS website these items are spreadsheet driven and they conflict with the MRP system interface we are using here.
All my formulas seem to be going nicely until I have to enter the square factor into the formula. [i.e. (d0)^2 or powr ((d0):2)]
It just will not accept syntax function. I have an idea the problem my lay in the unit types in the equation or the previous equations.
The formula I am trying to achieve is
Hr = sqrt(Fr^2-(1.4ul*DR-0.5ul*PITCH)^2)
Refer to JPG for clearer picture as to where I am coming unstuck.
The setup is: I have a rule which first gets a number of user parameters via input boxes.This rule then runs a number of other rules, using:
iLogicVb.RunRule("Rule 1")iLogicVb.RunRule("Rule 2")iLogicVb.RunRule("Rule 3").Each of these rules control parameters, part/feature/constraint suppression etc. in the top level and subassemblies/parts based on the previously obtained user parameters.
All the rules have the 'Don't run automatically' option selected, so all should only run as intended when I manually run the first rule.When I run the first rule, I enter all the parameters, and the subsequent rules run.The problem is, the suppression states etc. in the subassemblies/parts do not update.
Looking at the parameters dialog box after the rules have run, all user parameters have updated with the new values.If I run the first rule again the subassemblies/parts update correctly.
It appears that the rules that control the suppression states etc. of the subassemblies run using the initial values of the user parameters, i.e. the values as they were before the user input is obtained, rather than the new values.This is confusing me, as the code is structured as follows:
user_parameter_1 = InputBox("User Parameter 1", "Input", "xx")user_parameter_2 = InputBox("User Parameter 2", "Input", "xx")iLogicVb.RunRule("Rule 1")iLogicVb.RunRule("Rule 2")
I have a driven dimension in the attached part. If I change something in the part that affects the dimension it won't update unless I double click it to get the edit dimension dialog and then confirm it.
Changing the contour flange's length will affect the driven dimension which can be found in sketch5 under cut1.
I have 2 parameters in a part (a spring), "diameter" and "Length".
I change these parameters with iLogic to build several springs.
Is it possible to update the "Part Number" Each time I change the parameters "diameter" and "length"?
I want to get the following:
Mola_Ø-65_L-140
Where 65 is the parameter value and 140 is the length value.
I tried with the code below,
iProperties.Value ("Project", "Part Number") = "Spring_Ø-" Diameter "_L-" Length
but that returns: End of statement expected.

How can I change the precision of Driven Dimensions. I have a Driven Dimesion in a sketch that I want to use in another dimension later. Let's say that d59 is a Driven Dimension.I want dimension d80 = d59*2. When I measure it using eight decimal places, I can see that it is rounding d59 to 3 decimal places, but I don't want it to do that because then d80 is off.

View 5 Replies View RelatedI would like to create an equation driven curve with inventor. I have no problems plotting the function in a plotter, however, inventor won't accept my equation. It gives me the error message, saying: "The equation contains unit errors". I'm using the explicit equations.That's the bare equation:
"y=sqr(2)*16.5/2/sqr(pi)*sqr(arccos(1-2*x/50)-(sin(2*arccos(1-2*x/50))/2))"
I modified it, inserting variables which I defined also in inventor, leading to this:
"sqrt(2)*height/2/sqrt(PI)*sqrt(acos(1-2*t/length)-sin(2*acos(1-2*t/length))/2))"
But both equations are not accepted by inventor due to unit errors. In this design, I'm using the metric system, millimeters, so I don't understand why and how I have to redefine this for the equation in order to get it working.
Is there anyway to add a driven dimension or reference dimension as a column chooser? What I am really trying to accomplish is to show the metric and english dimension in my general table for my ipart. I model itself is dimensioned in metric. I now would like to add the english dimension next to the metric one.
View 6 Replies View RelatedHow can I create a flat belt driven system? The drive system and the flat belt are in the attachments of this message.
What I did until now was to create a part for the belt within the assembly (extrude part). The sketch is depending on the position of the rollers and everything else. Although when I create the belt I can no longer move the system. If I suppress the belt, move the system and unsupress the belt, the belts assumes the new positions.
My purpose would be to be able to still get a variable assembly so I could also make a dynamic simulation of the system.

View 9 Replies View RelatedWe are having issues with text height and variations depending on how the text is added.
I am currently adding etching to sheet metal parts by using the user parameters (which are driven by 3rd party source, excel file) and using a cut extrusion -1mm.
We have developed a marco which detects the shape of each letter and adds etching to our sheet metal program manually. We do this to get rid of the double lines when you cut text into a part. Our process is design in Inventor, unfold then convert to DXF 2004, where we import to our SM programming package (Radan).
I have noticed that when using 10mm simplex if the text is driven by parameters and 10 point text is selected the charecter height is 9.9928mm, however if the text is added manually it measures 10mm exactly. Why is this happening? It is probably of no concern to most, but we would need to add extra charecters to our macro to account for the descrepency, and in turn would take the macro longer to run.
When the text is added by user parameters, you can briefly see the 10mm text height flash to 9.99mm when finishing the edit sketch. Changing this to 10mm again has no effect.
what is causing this, or have any alternative ways of adding 10mm simplex single line etching to a dxf from an Inventor 2012 SM part?
I am using a link to an .xls worksheet to populate a General Table in my .idw (Inventor 2012). See attached. The blank space underneath the first lines of information will always be blank, no matter how many rows we get. Is there a way to have the drawing hide the blank/empty cells, make the borders invisible, etc?
I have tried using the Insert Object for an Excel file instead of using the Table feature, but it does not appear to be an updatable link. As in, if I change data in my .xls file, it won't update the inserted object to the same info.
I have a flange that I use iLogic and the parameters list to update the different styles. My problem is that my flange won't update until after I hit save and update.

Is there anyway I can get my round flange to update immediately like my square flange? I attached pictures below.
