AutoCAD .NET :: Polyline In 3D Space
Aug 26, 2013
I have the following points that when connected create a polyline (Px = X,Y,Z)
P1 = 149.941738,99.586521,6999.370079
P2 = 146.5869,91.262907,6999.250781
P3 = 143.883334,82.716622,6999.701863
P4 = 142.39435,83.120478,6998.429138
P5 = 141.276439,98.451501,6993.00069
P6 = 130.73509,105.487377,6982.747181
P7 = 131.486628,107.340559,6982.777312
The points are not lined up with any standard axes, but do have a common plane. I would like to create a polyline using the points above. I have tryed playing with 'polyline3d' and 'transformBy' but could not get it to work.

Opened a 3rd party drawing and created a new layer for space allocation boundaries. this new layer has the default lineweight. when i draw a line, all is ok. when I draw a polyline. its really thick and not the default lineweight.

Is there a way, when you are drawing a polyline, to have the tooltip box show the cumulative length of the polyline, rather than the length of the current segment being drawn?

I would like to take all the vertices out of a multiple-vertices polyline so that it reduces to just its start and end points, can this be done?

Due to modeling purposes, I need to convert a 3D polyline to a spline. What I have been doing is:
- change polyline fit/smooth to cubic from properties
- convert polyline to spline by typing spline -> object
- method -> fit from properties
You can see the original 3D polyline (green) and the resulting spline (magenta) in the attached drawing.When I zoom in and measure the distance between the two entities at different points along them, at some points the perpendicular distance exceeds 5 millimeters, and I want to ensure the deviation remains under 1 millimeter or even less.
I know I can change the knot parameterization of the spline, and this does work at some locations, but the difference increases at others.Why is there a 5.6 mm difference between the spline fit point and 3D polyline vertex, as measure in the attached drawing?
Now, I can go and manually stretch the fit point to coincide with the vertex. Also, I can add fit points between existing ones to drag the spline closer to the original 3D poly.
However, some of my polys are really long, and it is very time-consuming to do this manually while measuring points along the entities to make sure the distance stays small enough.
how to automate this process? For example a lisp that would maybe take the original vertex points, add say maybe 3 (not too many) new ones between them, and then generate a spline while making sure the deviation is less than the set value of 1mm? I am using AutoCAD 2013.

I've been working on a custom polyline object, and I've got it functioning!!Having said that, I plan to run its creation around picking a point for bounary selection.
(Other than trying to step through every vertecies) is there a technique I can thow the polyline data from a traceboundary result into my custom object? I've been trying to add the polyline from traceboundary to my object BEFORE it's added to the transaction by the way...I assume that's right, since I want to put it's data in my custom object then add my custom object to the transaction instead.

Is there any way at all to draw a new polyline - from the endpoint of another polyline, and have it automatically join as one polyline from the existing section??
I know this can be done via PEDIT, but its so laborious and soo many clicks, and I have alot of segmented Polylines that I need to consolidate when I draft.

Any way I can align a new polyline to a reference polyline (orig polyline).
The 2 polys will be generally the same length, however, the number of vertices will differ.
Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.

In 2012 Autocad, cannot change from model space to paper space, or paper space to model space without locking up in several drawings.
In 2012 Autocad, cannot change from model space to paper space, or paper space to model space without locking up in several drawings.
I can log into another user's computer and open the file fine. But when i use my computer or a brand new computer fitting all Auto CAD specs, it locks up. When I plot I have to reset my settings to the PTE standards every time.
I now get CAD errors when CAD is not even open. Also VTPSUHM barely works. I generally have to restart my computer several times to get it to work.

Lisp that would permit Toggling from Paper Space into the same zoomed area within Model Space and vice versa.

after discovering zones and the space evaluation tool I wonder whether it is possible to customise the XLS output further by also reading out information from a property set attached to the space?
The office standard is to have a property set attached to each space that defines a room number (which is the level ID plus a number, say G-01), the area and the space name.
We used to simply schedule the areas with a schedule table. That only gives us net rooms, no subtotals per department (or say per flat) and no grandtotal.So we got as far as using zones grouping the spaces in each flat.
Now I need an area schedule XLT template that also displays the room number from the space's property set and the schedule grouped in a fashion that I get subtotals per flat (=my zones) in another column and a grandtotal.Playing with the Space evaluation tool I seem to only ever get Room/ zone names and their areas.

I am a landscape architect trying to xref in civil backgrounds. I have noticed twice now from two different civil firms that some of the civil symbols (dynamic blocks) are having visibility issues in paper space. No the viewport layers are not turned off or frozen. No the views weren't placed using the sheet set manager. Yes the blocks are created on layer zero and yes the associated layer is not off or frozen. I don't believe these blocks are annotative blocks. They appear, as expected, perfectly clear in model space. I just toggel over to paper space and "poof" they've disappeared.

I'm trying to create a block that reads the x and y coordinates of a point from the end of a leader. Which is fine and easy enough if I use the block in the same space.. ie model space or paper space (layout tab).
However I wan't to be able to capture the coordinate from the model space, through the viewport, and pass it onto the block in Paper Space. Is this possible?
Or is it a case of having to use a more LISP based approach?

I'm running ACAD LT 2013.
I have a solid hatch that is in model space (actually in an xref in model space). When I use multileaders (in paper space) and point into the hatched area, that part of the multileader becomes hidden. As if it was a layering or object arrangement issue.

I feel like I have a vague memory of once learning how to click on an object in a viewport and being able to click a button or use a command to switch that object to paper space (so that it appears the same size). I'm trying to avoid having to go through the steps to scale down the object once I get it in paper space).

Im working on a student version of Architectural CAD 2012 i drew a floor plan and used AEC Dimensions on my model space but when i switch over to work space they don't show up. I tried matching properties and switching between paper and model but so far no luck.

I have several viewports rotated in paper space. When i set them to let say 1:100 scale go to paper space and then click into viewport it comes back to zoom extends of model space and i have to set it all up again and rotate it.
Second problem is that I've created wipeout in model space when i go to layout (paper space) ti looks just how i want it.
When I go to preview or plot it doesn't recognise any wipeouts?

I need to have users plot to DWF from paper space so they can retain their customized layers colors etc, on that specific paper space tab, as well as the view via viewport that they like most.
I then am mixing this with FDO data generated out of Model space. Unfortunately, when using the EXPORTLAYOUT command, the data is coped into Model space but seems to retain it's paper space coordinates. I had hoped this function would behave like CHSPACE and copy everything from paper to model space in the same scale.
Is there a way for me to achieve this?

ACAD 2010 text doesn't view the same in MSpace and PSpace! Model space is the acad default text: txt Paper Space it appears as it should as Romans. The drawings print as txt and not as it should Romans! When I change the text in model space to Romans, save the drawing, enter PSpace and the return to MSpace, it seems to 'reset' back to text!
This is specific to my workstation BTW, when I open the dwg file on a colleagues PC it opens Romans in both Model and Paper space.

I just started a new job and am struggling to set everything up the way my old company had AutoCad configured. My old company actually had people that were involved in writing the code for AutoCad on the payroll, so hopefully what I'm looking for isn't some intense computer programming issue.
In short, I am trying to be able to create a generic title block in model space, and reference that title block into paper space of a new drawing without having to create a new tab or anything first. A new paper space tab is automatically created upon attaching the new title block. My old company had its own custom menu bar with lots of custom commands, so the work flow would go something like this: "Old company name" in menu bar -> "Insert" -> "Title Blocks" -> "24x36 title block" (or whatever size we wanted to use obv). Once the desired title block size was selected, a new tab would be created in paper space with the title block as an xref, and a copy of the generic title block was saved to the main folder containing drawings of the project, and could be edited with the specific project info from there.
Is there a semi-easy way to do this, or is this a coding issue that a non-programmer such as myself might have some difficulty doing?

I use x-ref's inserted in model space and label in paper space - always.
I would like to see a way of locking out model space while editing text in paper space. Unless you double click right on the text, you often end up in Model Space...I know - big deal right? It can become annoying or a big deal when a deadline is looming - when is one never? Also big fan of locking viewports.
