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 am really in need of knowing how to convert splines to lines?

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?
is there any way to convert a bunch of splines into a poly? Its going to be a city, the shape is given. I need it as a poly, now its just a bunch of splines.

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.

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!!!
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 Relatedis 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.

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 2 Replies View RelatedIs 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 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:

I 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 am working on a drawing with a lot of splines. I need to dimension the curves to some rational dimensions which means I need to convert the splines to arcs. Is there away to do that?

how to flatten or z values to be done zero for rotated dims & splines?
when if u r viewing dwg in isometric views for keeping all the z values zero. commands for acad2011 format?
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.
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.

View 4 Replies View RelatedI 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.

Using Inventor 2014.
I was going to send autocad drawing to our client.
I found that converting IDW to DXF/DWG doesn't always get 1:1 scale on the DXF/DWG drawing.
In other words, some drawings are fine and the others are not.
It was set correctly in "Options..." by selecting "Base View Scale - Model Space".
There is nothing wrong with IDW files and all these files are using same template.
