AutoCAD Inventor :: Converting Equation To Numeric?
Mar 23, 2012
I was trying to use ipart to create some parts and place the relevant dimensions in the table format in the idw file. However, the equation for the dimensions appeared and I like to have it as numeric. Also, the feature present or absent is preferred to be called "Yes" and "No" instead of "Computed" and "Suppress" respectively.
When a revision is created we bump up the revision using a letter. If there are multiple changes done to the drawing during that revision we will use a number to indicate that. For instance; if I have 3 changes to the drawing for Rev C they will be tagged as C1, C2, C3. However the drawing Rev in the title block should only display C.
Is there a way to make the revision block do this? Right now we place in the DESCRIPTION a note like 1. Added Dim in zone E10. 2.Text was "Flat" in zone H3. But this for goes the ZONE column that comes with the revision block and makes it difficult to edit because you cannot see the entire description while editing.
In an Inventor Drawing (.idw), dimensions are formatted (i.e., as decimal or fractional) based on the style selected for the dimension annotation. You can also force stacked-fraction formatting of specific numeric text within a text box.
However, text boxes don't seem to offer much control over retreived parameters. When you insert a value from the parameter table into your text box or leader text, the retrieved parameter always gets pulled in as a decimal number regardless of how it was formatted in the part's parameters table.
Are there any formatting functions that can be used within a text box or leader text to force fractional formatting for a retrieved parameter embedded within that text?
I have a text parameter "ARM_TYPE" that kicks out a numaric parameter "ARM_ANGLE" through an ilogic rule. My problem is i need to have the rule kickout an error when (ARM_TYPE= "none"). I can do this by changing the "ARM_ANGLE" parameter from a Numaric to Text format (see below). The problem here is that "ARM_ANGLE" is used in several more ilogic rule calculations generating other parameter values which also need to kick out an "error"
I need to make a model of saddle surface. The surface is given by equation z = y^2 - x^2, and I must have some thickness - It will be printed on 3D printer.
I have Inventor 2014 and I dont see possibility of making the surface directly in Inventor. Is there any trick for that?
I'm afraid I cannot use solution as stated here Equation-driven surface , because saddle surface looks like this hyperbolic paraboloid .
I tried this solution: I made 3D surface in Matlab, exported it in .stl and opened in Inventor - but this only makes the surface with no thickness. Functions extrude, loft require 2D sketch.
Can an equation be used to calculate equal distances when using the rectangular pattern.Regarding the attached .ipt file i would like to place 25 holes in the X direction with equal gap size between each hole.Also how to calculate the number of holes in the Y direction again with equal distance between each hole.I have not done this before with equations but was thinking that i would need to use the Length x Width in the equation.Do i need to add figures into the Parameters box also?
The attached file with the Hole feature the sketch is not constrained for the purpose of using an equation so i know how far from the start of the part to get equal distances between each hole to the end of the part .
We have some equations in our templates which i have modified with iLogic. Once the rule is run it only shows the value and not the equation. ie i want it to show Thickness*2 instead of just '12'. The ilogic will say something like InnerRad = Thickness * 2 Is there a way to make it show the equation rather than the value? While i know whats going and can see the driven link in the parameters the planned change to 2012 could take some getting used to for users.
I have an asssembly stack and I have a known bending moment at a given place (ie the datum). I want then to create a drawing of this stack up and show the bending moments at known locations beside the relative dimension.
Now I can do this manually no problem...but I would like this drawing to update automatically. ie the stack up height(s) change and i want the bending moment figure to update accordingly.l
Is there a way to do this with drawing dimensions? ie dimensions created in drawing mode?
I'm trying to use the equation curve to draw a super ellipse.The formula I'm trying to translate for inventor is the following.I'm guessing this should be possible using the abs() for the first section and an IF() statement for the second. The problem is Iäm not even getting the abs() to work at all. How to translate this formula?
I have a small assembly with the parts. I'm doing an array (pattern) of one of the parts and I tried to do two things without success:
1. Tried to link one of the parts to the assembly itself with the equation tool ,but the software doesn't let me do it and says "...was rejected since it causes a cyclic dependency" - so what?:-) I know and need to do it!
2. After rejected the first choice, I tried to "project geometry" some stuff of the pattern I created in order to try and and make my connection in this way, but then I got a similar rejection: : problem encountered when doing cross part projection"...probably it's because it's from a pattern I'm creating from the part I'm doing this sketch inside?
What Can I do in order to bypass these remarks and make it somehow? Most important, Why can't one "tie" something from a part to its own assembly in which it's located???
Is there any way in which the text of a text parameter, which is in the equation column, can be replicated into the nominal value column in the parameters table? I want to reference the value of the parameter in Custom iProperties but it always comes up as blank because it has no value.
I need it to update automatically, e.g not entering the value manually.
what the 2D or 3D equation curve for a parabolic spiral, otherwise known as a Fermat's spiral would be? I have found this info but do not know how to apply it:
Fermat equation
Therefore in terms of the affine plane its equation is The Fermat curve is non-singular and has genus
I am trying to create a coil which from above, retains equal and thus parallel pitches whilst at the same time adheres to a semi-circular form in the cross section. You can see from the images attached that the first two revolutions are larger than the semi-circle outline.
These are the values I have used:
Cylindrical
r (t): 134.56924424045517662353735770102mm * t * 0.5 q(t): 1 deg * 360 ul * 3.0 ul * t z(t): 10 mm * 6 ul * 0.5 ul * t * (1.5 * t) * t
When you sweep a profile along a helical path, use the plane normal sweep (instead of perpendicular sweep) to orient profiles suitable for coil or spring. In the example below, the sweep path is a constant radius, variable pitch helix.
I 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:
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 a way to graph a curve using an equation over a closed interval in Inventor 2012? I know I can draw a spline through points that are solutions of my equation, but this does not guarantee that the curve is the graph of my equation.
I have an iPart that I have created parameters to perform some basic calcs so the values will show up on every member. The parameters are correct for the different member so it appears to be working correctly on the model side. For example I have a parameter called 'CutLength' that performs simple math functions. But when I make the table on the drawing and I include this parameter, I see the formula in the table instead of the value. Is there a way I can have it display the value instead of the equation?
What my problem is; i want to express an if function like if P1 is out of my EG and Distance to Surface is error value OR P1 is inside the EG and Distance to Surface is a numeric value.There is the attachment to explain it.
I have numeric values [St_NUMB] I'm adding as labels. I see that Map is converting them to strings [TOSTRING"(ST_NUMB)"]. The ST_Numb refers to a street number for a a house, and any outbuildings are labels as '0' (zero) since they are not technically an addressable structure. I have a large amount of data with a value of '0' (zero) that I would like to filter out of the labels. I'm really not sure what expression or command is the simplest to use.
In 2D I need to create some alpha-numeric content that will be uploaded to a CNC machine for production.
For example the numbers '7 1 9' and characters 'U N I T' need to appear on screen exactly as they will be when CNC machined from metal.
I am not sure what the capabilities are of Autocad for this kind of work in terms of WYSIWYG and what kind of styles I can create. In particular my requirement is to have the alpha-numeric characters quite substantial and not 'thin' (so far I can only think of using bold).
