Is it possible to match the ends of two splines (whose end points are coincident) such that there is tangency between them. This would require the end control vertex (CV) and preceding CV for each spline to become aligned? I have explored the SPLINEDIT options and see there is a FIT DATA option that leads to TANGENTS option but I'm not sure how this works and whether it will give the desired effect.
View 3 RepliesIf 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?
View 3 Replies View RelatedI 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 have topo contours that are splines. I want to flatten them so they become polylines that I can give elevation values. When I flatten some, portions of the topo lines become circles.
How do I fix it?
I am using Autocad Map 3D 2011. I am looking for a way to edit multiple splines at once similar to the multiple pedit command. I need to convert them to plines. I have been selecting them one at a time, typing p, enter enter enter, selecting the next one and so on but it would be a time saver to be able to select multiple splines and have the "convert to pline" command work on all of them. As it is, if you select more than one it only acts on the first selected.

View 9 Replies View RelatedGot a strange problem when copying geometry that contains splines between drawings.
The image below shows the results, the white dashed line shows the copy result, the blue dots are the control points, and the red line shows the copy input.
It seems that the control points are correct, but the tangencies of those points, or control vertices are WAAAAAY out.
I also get the same result when inserting the geometry as a block..
I'm writing a script file that will make a few splines and loft them. I wrote out the lines of code and saved the file as a .scr. When I load the script, it will do the first spline but it will not graph the second. It takes the spline command as if it were another point. The text window for the end of the first spline and beginning of the second reads like this:
Specify next point or [Close/Fit tolerance] <start tangent>:
0.000000,0.000000,0.010000
Specify next point or [Close/Fit tolerance] <start tangent>:
Specify start tangent:
Specify end tangent:

How can I convert arcs to splines.
View 5 Replies View RelatedI have a bugging problem.
I usually use Inventor to create a model from customer supplied blueprints, and then use the model to get the 2D geometry into
AutoCAD for further processing.
Now, unfortunately Inventor has a pitiful 2D drawing method, where circles and arcs that do not lie exactly on the plane end up as a spline.
They are true arcs and circles and should be true arcs and circles on the 2D view, but aren't.
What I would like to do is turn them into one.
Is there any command or method to do that?
I was hoping that Overkill would work ..... it doesn't.
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.
View 5 Replies View RelatedI searched and saw lots of posts on converting a spline object into a pline, but not the other way around. I like the way that splines can use control vertices or fit points.
I know that you can apply a spline smoothing to a pline, but what I'd like to do is to convert a pline object into a spline object and splining a pline does not do that.
Any fairly easy way to do this? Are there LISP routines that do this?
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!!!

Sometimes, not in every drawing, but in certain drawings when we draw a spline it creates a jog or tail.
So when we do the command spline and click the start point then move to do the next point it will have this jog or tail at the beginning of the spline. sometimes we get it at the beginning and sometimes at the end.
How do I make it stop? is there a setting that I need to change? We typically work on drawings from Architect / Engineers.
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?
View 9 Replies View RelatedI 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.

I am trying to hatch a long curved path that is composed of polylines and splines that I manually joined together by pedit. When I try to hatch it, I get an error message that says the area is not closed and thus cannot be hatched, but I have no clue where the problem area is. Is there a way to figure out what parts aren't lining up/closed correctly? When I select the object, it shows that all the lines are connected, so I don't really know how to fix this.
View 9 Replies View Relatedi used to do a lot of spline extracting from geometry, mostly to use sweep modifier to modeling. But i usualy got a problem when i do that, some of the splines are "flipped" (or reversed), causing a problem in sweep geometry. In attached image, i extracted the splines from the faces below, and when i apllied the sweep, some of the splines get a different result. I tried to collapse the spline, reverse, flip the geometry normals, reset xform, create another spline and attach the extracted one, and nothing solved the problem. What i usualy do is to detach part of the spline and apply the modifier twice.
View 6 Replies View RelatedI have recently decided to restart on an older project, made in some older software long ago, a somewhat simple racetrack.
I decided to load this model into 3DS, and modify it to add several alterations and some heavy modifications. In order to retain it's original shape. I had decided to convert it to a Spline. According to my plans, this was the best solution, apparently.
And that's where the issue settles in. Due to the fact that the model was triangulated, when I selected the "Select Edges" and "Convert to editable Spline", the model became a skeleton of it's former self, and when you delete the un needed vertices the remaining spline consists of many un connected points, thus making Path deform and Sweeping impossible.
I cannot weld the vertices together, every attempt made thus far had been un productive, the vertices remain un connected and un usable.The spline in question can be viewed in the attachment.
I am looking for a way to deform an object using splines, i know you could do it with a path constraint but i dont want it to travel along a path i just want to be able to deform it with a spline,
