AutoCad :: Copying Splines Between Drawings?

May 9, 2012

Got 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..

AutoCad :: Copying Between Multiple Drawings?

Jul 6, 2011

I'm having some trouble while copying between drawings. I am attempting to merge a number of floor plans which are all saved as seperate drawings into 1 drawing. However whenever I copy the floor plan over to another drawing, some of the lines/objects seem to be displaced.

AutoCAD 2010 :: Copying Layouts Between Drawings?

Jun 7, 2012

I have been trying to figure out how to copy a Layout from one DWG to another. I know there are several threads about this, and I have tried the methods they reccomend, but I am having an unusual problem.

I have been trying to open a Layout by using the "from Template" option for creating a new Layout, then opening the DWG containing the desired Layout. It works, but everything drawn in model space ends up compressed into the lower left corner and there is nothing in model space. So, the paper space information from the Layout is being imported, but the drawing info is getting mixed up somehow.

I have tried using the Design Center with identical results.

AutoCAD .NET :: Copying And Pasting XData Between Drawings

Sep 8, 2011

How can know if entities are being manually copied and pasted between drawings.A thought is to add a GUID to each entities Xdata and check if the value is in the named object dictionary.

AutoCAD 2010 :: Copying Blocks Between Drawings?

Jul 7, 2012

I am doing electrical drawings with the architect giving me an exported DWG from Vectorworks.  I have XREF the background drawing that when opened is about 6 blocks of the building background and 2 blocks of the electrical devices.

Here is the problem: The architect sent me an updated DWG that only has the electrical updates without any backgrounds.  My thought was to purge all and then select all the items and then copy with basepoint.  Then open the original architects XREF drawing.  Select those two electrical block, erase them (or move them to the size a fixed distance).  Then paste as block from the other file.  Then move the block to the correct location, explode, done.

Big problem: I just tons of this error in the command line referencing different block group numbers being ignored:

Duplicate definition of block Group-1265-1  ignored.

Then the block that was pasted added a background that wasn't in the old drawing and many of the items in that block was either missing or still had the old symbols.  Can't figure out how to update the background with confidence that it is really updated with new information and not keeping old.

If I open a new drawing and paste that block in, everything comes in perfectly

AutoCAD 2013 :: Copying Drawings To A Sub Folder

May 28, 2013

We are copying our original files to a sub folder to make revisions that have only happened after bidding. We want to keep our original bid documents intact. I have created a sub folder called 'Confirmed Documents' and added Constructs, Sheets, Elements, etc. 

I copied the files over and used the Reference Manager to repath the files. However, all of my schedules and room tags now use the 'NA' prefix because it is not reading the project information. How can i reconnect this folder to the project folder?

I'm a new user of AutoCAD. I am creating a template, but when I try to drag or copy and paste the layers. blocks, dimstyles, multileaderstyles, etc. from design center, a message pops up that the parameter is incorrect, or it would just not drag and drop. I have the original drawing open as instructed, but nothing seems to work.

AutoCAD Inventor :: Convert Splines

Dec 26, 2012

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.

AutoCAD Map 3D :: Edit Multiple Splines At Once

May 27, 2011

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.

AutoCad 3D :: Matching Splines Together With Tangency

Feb 11, 2012

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.

AutoCAD 2010 :: Splines In A Script?

Mar 7, 2012

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:

[code]....

AutoCAD 2010 :: Converting Splines Into Arcs

Sep 23, 2011

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.

AutoCAD Inventor :: DWG Or DXF If Creates Splines In 2d Drawing

Jul 12, 2011

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.

AutoCAD 2010 :: Convert Plines To Splines?

Mar 15, 2012

I 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?

AutoCAD Inventor :: How To Stop Creating Splines Of In IDW

Sep 23, 2011

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!!!

AutoCAD LT :: Can't Copy / Paste Between Drawings/ Incomprehensible Heavy Drawings

Dec 28, 2012

I'm using ACAD LT 2008.

When i try to copy paste some drawing entities from a heavy drawing file to any other file, the program blocks and says 'not responding', endlessly. So i always have to shutdown the program. I experience the same problem using the designcenter: when I try to copy a layout into another drawing, my computer gets stuck.

Another annoying problem with these files is that they are so heavy, while in fact they shouldn't be. I tried the aectoacad file command. In result the file id half as big, but after I open it and save it, again is the original size.

AutoCAD LT :: Publish Drawings To Overwrite Existing PDF Drawings

Apr 2, 2013

Every now and then I go back and try to use publish to speed up printing but I always go back to plotting one by one.

I work in a housing construction office and I have 10 separate drawings side by side in model space for house plans that I need plot separate to give to certain people. My problem isn't that I can't publish them separately its that I can't save them over existing pdf's individually predetermined. 

Q1. do i just have to go through and change every layout name before or after i publish?

Q2. how do i change the output publish location?

Q3. can each layout be saved to a different existing pdf and remember it?

Q3. can i save these setting across to a new drawing?

AutoCAD VB :: How To Manipulate Existing Splines On A Drawing By Joining Them Together Via VBA

I'm new to VBA in AutoCAD I've played with Inventor VBA a bit, but the API appears to be drastically different.

I need to manipulate existing splines on a drawing by joining them together via VBA. To achieve this manually, the user would use the command SPLINEDIT and go from there. What is the equivalent, or how do I access the command in VBA?

AutoCad :: Draw Splines Creates A Jog Or Tail In Drawing

Sep 13, 2012

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.

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?

AutoCAD 2010 :: Splines Are Drawn By Connecting Ends Of Two Lines

Oct 18, 2012

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.
