AutoCAD Inventor :: Fairing Splines And Making Tangent Lines?
Jun 9, 2013
In other softwares when you creat a spline you are able to adjust the curvature between points by dragging the slope handles at a node. In my file, I have thus far been unable to fair my splines with any kind of consistancy. Also, it should be possible to place a tangent constaint to a straight line at a point, yet I haven't been able to do that either. According to the help files this should be an easy thing to adjust, Why am I not able to?

I used Solid Edge for my entire professional career. One thing that is driving me batty is how, when necessary in a view for clarity, tangent lines are displayed and how to change them, or at the very least, come up with a work around to display them how is needed. In general, tangent lines are first, supposed to be of thinner lineweight, but also, are not supposed to extend all the way across the surface of a part, they are to leave a small gap.
I have found and tried the option of displaying tangent lines, and also have checked the for shorten option. The issue is, in many of the parts the gap produced in HUGE. So I've spent a few hours tinkering, and I finally decided to try and define a new linetype using autocad express tools. So I tried this, but to my dismay I haven't been able to set up a linetype that only has a gap at the end. See attached jpeg for illustration.

I use splines a lot to provide a contiuous smooth curve between two lines which are co-planar. The splines are drawn by connecting the ends of the two lines and then the tangent direction set by hovering over the end grips. I then use the FLATEN command to convert these splines to polylines that can have their lineweights set to a value other than 0. My problem is that sometimes when i use the FLATTEN command, the spline is erased.

So I have a student who wants to put these lines in the object. Since it would be very difficult to make these lines enclosed and looking right is there anyway to put these lines in the object. I don't understand why Emboss works on letters but not lines. That is all letters are.

I am working with a drawing provided to me by someone else, and where there should be arcs they have multiple line segments. I need a radius for what I'm doing, so I drew a circle with TTR and then tried to trim against the tangent lines to get my arc. However, sometimes this works and sometimes it doesn't. why this doesn't always work?

Was wondering if there is a way or a plugin for 3dsmax to use splines or nurb curves to create "Jura"-like line patters- the exact thick and thin line formation you would see on a dollar bill. To create curves, and contours, around text and shapes.

If I have imported a large multi-spline object, is there a way to bust it up into separate splines easily -- without having to detach each one individually?

I have a drawing of a map full of polylines and some splines. I want to somehow select or show only the splines for then to convert them into polylines to make them ready for laser printing.
The drawing has thousands of lines so selecting one by one to see if its a spline will take forever.

I need to export faces on a part. When i do this in either DWG or DXF if creates splines in the 2d drawing. Then i have to go back and redraw all the radii. Is thier a way to convert or export without getting splines? Our machine won't recognize the face drawing unless i redraw all the circular segments.

how to stop Inventor from creating splines of in IDW where the geometry is in fact a true arc or circle?
This is absolutely ridiculous and maddening!
If it is a freaking arc or a radius, then make it a freaking arc or a radius instead of a spline!!!
If not, then give AutoCAD a tool to convert a spline into a true arc!!!
Come on Autodesk! Not everyone is using your product for design, some of us are doing so to actually make the damm parts that are drawn in Inventor! A spline that supposed to be an arc is wicked difficult - if not impossible - to send to a waterjet, laser or EDM to cut properly!!!

is it possible to produce something like in the attached image using the design accelerator? Instead of making a cylinder and sketching the spline patterns and extruding? To me there must be a way besides sketching and use the library's of standard splines patterns and sizes.

This is probably a simple one, but when I dimension from an edge to the tangent of a radius or circle. It always snaps to the center. How do I get the dimension to snap to the tangent point?

I am still making some adjustments to our standard drawing template and I ran into another issue..
I want the tangent edges to be displayed automatically when I insert a drawing view rather than clicking the Display Options tab and checking the Tangent Edges box every time I make a new drawing. Is this possible? If so, how?
I tried inserting a view, checking the Tangent Edges box, then deleting my view and re-saving the template but it still went back to the default.

I have a roller pin which follows a certain path using transitional constrain in an assembly. A box is attached to the roller pin which move along with it. My problem is that I want one face of the box to be tangent to the path which the roller pin is following so that the box moves according when it is on the curve. I have attached the file with the message.

Since switching over to Inventor 2012 I have been having trouble snapping to tangent points on a curve or circle to pull dimensions. I would do it manually but if the dimension is not referencing a specific point in the model it turns pink to identify an error.
Is there a setting that may be not allowing me to snap to tangent points?

I am having trouble with a part that I am working on. Trying to trim to the tangent edge. I cant post the part that I am actually using, but here is an example of a similar problem. In the attached file, open the "Negative Part.ipt". The sketch 2 contains a line (unconstrained). I need this line to be tangent with the curve below it.
I can project the edge of the curve to my sketch plane, but not the tangent of the radius.

Looking at a side profile of a channel in a drawing, you will usually see a top and bottom edge, as well as some nominal flange thickness.
In Inventor, all you see is the top and bottom edge...because the channel's shape is really radiused on the flange.
So I turn on "Tangent Edges" in the Display Options of my view...now I see three lines representing the flange. I can manually hide the other lines, but this option creates a TON of lines in my views that I would have to manually hide.
What is the quickest and cleanest way to represent a channel without seeing a ton of extra tangent lines?

Is it possible to have a tangent constrain on multiple curves?
see enclosed rough sketch, i would like the curved free end or the arm to be in constant contaced with the wavey top line on the other part, the wavey line is constructed as 3 curves but i can only get the tangent constrain to apply to one of the curves.
i would like the tangent constraignt to move between the curves so the part stays in constant contact with the wavey line. this is just a mess about sketch i suppose a real world instance will be a wheel following a shaped cam plate.

How can I create a workplane with the API that is tangent to a surface and passes thru a workpoint. It is easy to create a work plane of type kPointAndTangentWorkPlaneDefObject by point and click in Inventor 11, but I can't figure out how to do it in the API.

I'm designing a part, and am having trouble creating a plane tangent to a curved surface. One option for creating a plane says "Tangent to Surface through Point", which in theory I should be able to use, but I can't figure out how to actually place a point there before in order to create a surface at the point.
Basically I am trying to cut a circle into the curved right side of the part
I've attached the part file for reference.

Is there any way to have Tangent Edges to show within all view's created on my idw automatically within the my template file or do I have to remember to double click on each of my created views per page, select display options and make sure Tangent Edges are checked on.

I am trying to create a dimension in an .idw that goes from a line to the tangent of the outer diameter. I have tried several approaches but I cannot get it to work. Essentially I am trying to replicate a drawing which was created in Solidworks but I am having trouble with this dimension.

I have created a bin/vat/tub using sheet metal. I started with a contour flange. I then copied the sketch and pasted into a new sketch off the flange for a contour roll feature. Then a flange, roll, flange, roll, flange and roll. My trouble starts at the last flange. I'm trying to construct the flange exactly as I have created the features before. I set the distance, select the profile (it shows the flange on the screen), hit apply and that's when my message shows up. "Non-tangent curves found in path: flat pattern cannot be correctly created. Edit sketch and add constraints to the curves. The sketch is fully constrained according to the lower right hand corner and the auto constrain button.
