View 1 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 RelatedIn 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?
Is there an automatic way to force a mesurement, to become Referenced? (driven)?
Even if sketch is not yet totally constrained?
If 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.
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.
I've created a shared sketch and have used it with various features. Sometime those features are suppressed. The model works fine but the shared sketch generates a sketch doctor error because the feature that created it has been suppressed. Is there anyway to make the sketch suppressed so it doesn't trigger a sketch doctor error? Inventor 2013
View 2 Replies View RelatedHow do I duplicate the 2D line work from a part level sketch into a drawing level (overlay) sketch?
I started a simple 2D piping system diagram sketch by opening a new part file and using a sketch to stick draw the system schematic including some annotations. Then I opened a new drawing file and made a base view of the part file to bring a view of the original sketch into the drawing.
I realize now that it would have been much easier to have created the schematic directly in a 2D sketch at the drawing level, which would have made editing the annotations much easier at the drawing level, and there is really no need for the part file to exist. I have no intention of creating a 3D model or "real" part in the .ipt file, was just using it as a jumping off point to sketch.
I was thinking that I could correct my error in judgment by just copying the sketch and pasting it into a new sketch on the drawing, but it doesn't want to work that way. I have tried copying both the whole sketch at the browser level, and the entire sketch contents (all of the lines and annotations) from the opened part sketch, but when I attempt to paste either of those into the drawing, paste does not seem to be an option. I'd rather not have to draw the whole thing again, as in typical fashion, my once simple sketch has grown in proportion and complexity from its simple beginning.
I was trying to query some sketch points data from a profile Path using code as below. However the program stopped without telling the reason.

View 1 Replies View RelatedI 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 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.

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.
