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 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 3 Replies View RelatedAs the above mentioned, I have a drawing drawn using polylines with width from someone. The width of the line are suppose to represent area,
To put things into prospective, here is an example:
The polyline is 10 unit long and with a width of 2 unit wide. If i explode that polyline, it will become a single polyline without width. The line are suppose to represent 10 unit long and 2 unit wide; representing an area.
My question is is there a way to change the line above directly from polyline with width to a close polyline (4 x polylines) of 10 unit long and 2 unit wide.

Is there a way of converting 3d polylines to polylines with an elevation?
I have a dwg of contour information, the contours are 3d polylines, because they are contours the z value is constant all along the line, so there no question what the elevation of the polyline would need to be.
I need to do this as I then need to import the dwg into a GIS programme called MapInfo whch doesn't read 3d polylines.
I have access to AutoCAD 2004 or 2005LT.
I have AutoCAD LT 2008 and need to be able to flatten 3d objects. I have followed all instructions for the plot to dxb and have successfully saved the files but now can't get them to open. What are the next steps? I have tried to open a new drawing and open the dxb file using the 'DXBIN", and "DBOUT" commands which show as unknown commands.
View 5 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 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 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:

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!!!

View 9 Replies View Relatedmake a drawing to be flattened and set to elevation zero.
I do have the flatten command from express tools, and that works only to make everything to 2d, but i need a simple script routine to set all objects to elevation zero.
This is my current methodology
1. select objects
2. flatten
3. select same objects
4. explode
5. select same objects
6. explode
7. select same objects again
8. In property's, adjust Z axis to 0.
I fear that this is too long and bulky, and sometimes it wont work.
I also fear that any lisps routines are completely out of my league as i never used them before and my company never really had a need for them, but i am willing to give them a shot if it means that they will save me some time.

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 am working on a design project for a class i am in, i need to make a model of the design solution i come up with. since my design has curved walls, how to take my AutoCad model and convert the faces to something where i could print them out on paper and make the model. I need to basically unroll them as if i was flattening them on a sheet of paper. i have tried flatshot and flatten, my difficulty with these is that it does not take the entire object length along the curve, it will only take the distance that can be seen on the screen. I know this is possible with 3ds max as a friend of mine did it that way, but i don't know how to use 3ds max so that doesnt work for me.
