AutoCAD Inventor :: Inserted Model Changes Form During Constraint
May 25, 2012
I have a model with 12 circular connectors placed (constrained) in the housing surface. well 11 of them are. The last one WILL NOT behave. when i use the insert constraint (or any constraint) the model of the connector modifies itself and becomes a new model with errors.
i have deleted it from the assembly, saved, closed, opened and when re - inserted have the same problem.
I have re-saved the connector model from its original location to the library folder, re-inserted and got the same problem. The connector model is fine in the assembly up until i try to constrain it.
all the connectors were drawn the same way, using parameters, and saved into the same library folder.
I don't understand how adding a constraint can cause a model in a diffferent folder to be modified.

I'm trying to put a little iLogic rule in my drawing template which triggers as soon as the drawing is opened. The rule asks the user whether the component he's making a drawing of needs to be painted or not. If it gets painted, the paint area (one side only or both sides) needs to be calculated. The result of this is then referenced by a text note in the title block.
I can do the radio boxes with the questions, as well as their If loops, but only when I'm in the model. Due to our, admittedly inefficient workflow, we never have time to specify "minor details" like paint area or spec during modelling, only when we get to drawing level. I'd like to put the iLogic rule inside the drawing template. I'm having trouble referencing the iProperties of the model from within the drawing's iLogic interface.
What I have so far is this rule, which I can run inside the model:
'set dummy variable equal to total areatotal_area = iProperties.Area'start radio box with questionsText1 = InputRadioBox("Will this component be painted?", "Yes", "No", Text1, Title := iProperties.Value("Project", "Description"))If Text1 = True ThenText2 = InputRadioBox("How many sides will be painted?", "Both sides", "One side only", Text2, Title := iProperties.Value("Project", "Description"))If Text2 = True TheniProperties.Value("Custom", "Paint Area") = total_areaElseIf Text2 = False TheniProperties.Value("Custom", "Paint Area") = total_area/2End IfElseIf Text1 = False TheniProperties.Value("Custom", "Paint Area") = 0End If
adding a line or two so that I can run the same rule, but from the drawing.
I am designing a vertical axis wind turbine just for some practice (just started using Inventor) and everything was going smoothly until I tried to "animate" it spinning. First, I set up a work plane that goes through the center of the structure, and then I clicked angle constraint "explicit reference vector." After watching several youtube videos, I figured that I should click on the work plane, click on another reference point, and then click another point that would be orthogonal to those two (right?). Well after I choose the first point, Inventor will only allow me to choose the center axis as the second option (which I think should be the third option).
I am working on a form (global) and have added a picture with a parameter and a picture folder underneath. So that the picture displayed on my form will change depending on the parameter value.Here comes the trick. Only text parameters can be used!On the form editor only 'Text parameter' can be selected to drive the picture selection. I actually need an integer, so that i can use my User/Excel parameters from Inventor.
I can work this around with an iLogic rule to equal the value of my string Picture Parameter with the relevant integer Inventor parameter, but the rules need to be run before the pic and the form updates (by pressing the 'Apply' button at the bottom of the form and then the assy updates too. So this takes a couple of minutes)... whereas if it was an option on the form editor then the update would be instant without waiting for everything to update...
Is there a particular reason why the Picture Parameter only can be a text parameter?
I have a drawing on which I am going to need to show some photos of the assembly in its installed condition. When I attempt to insert an image, I get very low image quality that is giving me flashbacks to mid-90's video games. I do not get any sort of errors, missing images, file names displayed instead, etc. The image appears, but simply looks terrible, both on the screen and if printed or converted to PDF.
I have tried inserting the image as JPEG, PNG, and BMP, all with identical results. It is not unique to these images, and in fact occurs even if I try inserting images that Inventor created in the first place. Searching on these forums indicates that changing file associations for BMP files to Paint may be the answer, but most of these posts are rather old.
Since my IT department has me locked out of changing these associations for myself, I'd like some confirmation that this is still the likely cause before I go through the red tape of an IT service request.
I'm trying to make this assembly flexible in that the bar will flex so the "s-clip" can hold the 2 handles together. I read some of the forums about the scissors assembly in the autodesk folders and I can see it working in that assembly btu can't figure out how to make it apply to mine. It is basically one of those camping grills that makes hot sandwiches or pies.
If I insert a part with my own work planes in an assembly, I can programatically get the first 3 standard workplanes and also the non standard workplanes.
BUT if I make the part a table based iPart, I cannot find the extra non standard workplanes in the WorkPlanes of the part component definition, just the first standard three (XY YZ XZ).
I insert parts in an assembly, new parts from content center or from a library, without projected edjes, they are free to move until i impose the first constraint, the axis to axis alignment of round parts, then i cannot move them anymore in order to continue constraining them
I have an assembly which has components mated to a radial surface, I need to locate the center of a round slot against an axis, I have X Y coordinates, how can I constrain that part to those X Y coordinates?
Maybe I've just been doing it wrong for the last 5 years, but the Angle constraint is obnoxiously unpredictable. When I constrain a part in an assembly with an angle constraint from the assembly origin plane (or anything else), Inventor always has two solutions; a positive and negative.
Is there something I'm missing here, or is just a design flaw we have to live with?
I am running into some trouble with user parameters that have been inserted into a dimension's "text box". I sometimes hide the dimension itself and insert these parameters so that iLogic can manipulate the upper & lower tolerance limits for a dimension.
The problem seems to arrise anytime one of the dimension's arrows becomes detached from the drawing (and perhaps for other reasons, too, although this is the only clear cause so far). I can reattach the arrow and the dimension seems healthy again, but if I go into the text editor, I notice that the link to any parameters that I've inserted has been lost. They appear as they were last set, but will not update if the parameters themselves change.
Is there a better workaround for this, or can we expect a solution in IV2013? I've invested close to a year's worth of work expecting this method to perform properly, and it will be a letdown if there's no solution.
When I add an image to my sketch the main body then appears "of the ground" as you van see from the attached screen shot. The shadow and reflection is distant. The minute I remove the instead image the object and the shadow touch again as it should be.
I have a drawing with several tables that are inserted Excel objects. In some cases, the tables are truncated after the tenth row (although some tables longer than ten rows are not truncated). I can't find any difference between the tables that would explain it.
I am currently having trouble creating a decal, i have inserted the jpeg image on an ipt file, as i also need to use the .ipt when designing current projects, but when i project the ipt onto a dwg the ipt is just shown as being completley greyed out? i know how to insert the image straight into the DWG file but for what i need it just isnt enough?
Is it possible at all to bring the jpeg image into an ipt. and have it show on the DWG file also.
I am trying to place a tubes cylindrical surface to another tubes cylindrical surface using add constraint. How do I specify which side of the target surface to apply the constraint ?
I have a question regarding a transitional constraint between a pin and a surface within an adaptive assembly.
I would like the pin and the surface to be transitional only when the two parts "interfere" with each other.
At the moment with the example attached part A is remaining tangent to part B, restricting the necessary movement of part B to function properly in the mechanism.
In simplified terms I need part B to be able to break free of the "transitional constraint" of part A under certain movement conditions within the mechanism.
I have noticed what I consider a bug in AI2009. When trying to delete a coincident constraint using the show constraint command, it is impossible to do so. All other constraints I can delete while I am in the "show constraints" dialog box, but not coincident constraints. As soon as I get out of the "Show constraints" command, the yellow dots are still showing and I can then hover over them and they highlight so I can delete them. Is this how it was intended or should I be able to delete them like the others while still in the "show constraints" command?
Is there a way to expand the constraint window so that I can see my entire parameter formula? In the image below, my equation is cut off in the "offset" window. Or am I supposed to be inputting the parameters in some other manner?
I'm having a really difficult time maintaining my parameters when making changes to the part I've made in the attachment. The control parameters for this part are:
-100 mm distance between 15mm circles -1 of the 15 mm holes -30 mm hole
I am new to inventor but I would also like to be able to set up my constraints correctly. I'm also not sure if my sketches are ideal for this part either. I usually get an error concerning my fillets from the base to the center support beam when I try to change the 100 to 75.
I've assembled a bolt and a slide block that is constrained to a base plate and am able to put everything in motion. I have the slide block constrained to slide the distance of the base plate and when I reach the end the bolt continues to rotate when, if this was a real part, should stop. How can I get this bolt to stop once the slide block reaches its ending constraint?
