I want to loft two rectangles using arc as a path , but i cant , 1st i cant draw the arc in 3d so i draw it in "Front" view , then i cant loft the rectangles using that arc as an path -"The selected entities are not valid" , maybe because i draw the arc in "Front"(bottom left), but i cant draw it in 3d?!! Here it is some screen shot:
View 0 RepliesI have 2 rectangles and i want to loft them by path.I want the path to be arc , but i cant draw the arc in isometric view. The objects are positioned something like thes 2 smiles. One is exactly above the other and i want to draw arc to connect them and then use loft but cant make the arc. I tried to draw the arc in Front view, but i then i couldnt use it as loft path.So how to make the arc in 3d?
View 9 Replies View Relatedwe used AutoCad LT 98 & hasn't changed when opening the same files in LT 2014. All curved lines (arcs) that occur in a recently-opened file look like two straight lines with an angle at the mid-point, so that from a distance they still resemble an arc but not at all when zoomed in. When clicking on the control points, it goes to looking like a proper arc, but the change doesn't hold after the file is saved and reopened. Is there a program-wide setting to change, or do the properties of each arc need to be changed individually?

This morning I came in and I cannot pan with my scroll wheel or double click the scroll wheel to zoom to extents. I have tried checking the settings for the wheel for pan and zoom and they are both at "1"
Whats even more frustrating is now all of a sudden I cannot enter dimensions for rectangles and other items with the small boxes that usually show up next to my item on the workspace (20" - "tab" - 12" - enter to get a 20x12 rectangle for example).
I have gone through every option section; I have tried rebooting my computer; I have looked at the settings for the mouse and nothing seems to do anything.
1st let me preface this with the fact that I know zilch, nada, nil about solid modeling. But I think the easiest way to accomplish what I'm trying to do is thru solid modeling and export the end result as (3D) polyline
What I have is 2 intersecting arcs with varying radii and ucs values. I'm guessing these could turned into regions and then subtract 1 from the other in order to find a list of intersecting points or maybe a splined pline. Or maybe they could be joined. Either way, if I DXFOUT the solids in R12 format, they become plines
I have access to R14 thru 2012

When I start drawing a line from a specific point in the drawing and type in the dimensions via DYN - relative coordinates work like a charm, but when I start a rectangle from the same point and type in the dimensions (via DYN) it wont work.
It does not change when I set dynpicoords to 0 or 1. Nothing else happens when I type @ or # or nothing as prefix.
Using AutoCAD Map 3D 2012 Im exporting a few subdivisions to MapInfo after doing my steps on a MAPEXPORT command to create a .TAB or .MIF / .MID which are the steps do below.
MAPEXPORT --> select format_ .TAB or .MIF ---> select my drawing manually ----> do my coordinate conversion -----> DONE..
When in MAPINFO and ready to open / import the exported .TAB it opens and places the drawings (subdivisions) in its correct coordinate I gave it, but the TEXT and ARC / CIRCLES do not come in to scale at all they are extremely large to a point where they can't be seen till I do a zoom all.
Whenever I try to trim two intersection arcs who have the same bending direction and similar radius, casue it is extremely hard to click on the parts that need to be trimmed off. See attached pic for reference.
View 2 Replies View RelatedI've got ObjectIds of a bunch of arcs that I need to convert to polylines for further processing.
I was thinking of using the COM interface and sending the PEDIT command and converting the arcs.
The only problem is I don't know of a way to put the objectids into a selection set, then call the pedit command and use the previous selection.

View 9 Replies View Related3 lines. 2 arcs. All coplanar, all meet end-to-end.
I set "Units/precision" to 0.00000000 and inspected them. They are all x=0 for each endpoint, therefore coplanar. I also did a point "ID" command and checked each endpoint approaching from both sides and confirmed that each pair of results was identical, so all the ends meet exactly.
I was under the impression that Join or at least PEDIT should be able to combine coplanar lines/arcs that all meet end to end into a polyline. Also, using the Express Tool's "FLATTEN" command doesn't work.
The reason I'm doing this is because I've drawn lines/arcs that trace along the midpoint of a sheet metal's material thickness, and this sheet metal has two bends in it and isn't flat anymore, so converting the lines/arcs to a single polyline will tell me how long the flat plate needs to be that will be ordered to create it.
Recently I created an elevation which included a door with leaded glass. When I originally drew the arcs and circles they were symmetrical and smooth, but now they are rough and ugly.

When I go to draw a box (rectangle or square) and I enter in exact dimensions or coordinates it is 1/16" off. I have checked my ortho (which is drawing straight) and my UCS. What else could it be? I am using Autocad 2014 and only drawing in 2D.
View 9 Replies View RelatedII have been creating rectangles using rec and because it is a polyline I get the "midpoint" nodes which I need to keep. I often have to modify these by increasing their length or shortening them, large numbers of them at times. Currently I have to select each "midpoint", of the rectangle, one at a time in order to change all of their lengths at one time.

I am trying to find a faster way to select the "midpoint" of several rectangles or some other way instead of the individual method that I have been using. I've tried trim, extend, and stretch. Maybe there is another that I am not considering.
Trim removes the bottom line completely and retains only 3 sides so this doesn't work.

Extend does the same thing and stretch works very different than what I am trying to do.
This is my exercise:

As advanced as my AutoCAD skills are I don't know how to specify the dimensions of a rectangle or square yet. How to know the prompts I need to follow after typing the 'rec' command in?
View 6 Replies View RelatedI create a surface. Then add a point file. The Surface boundary shows up but I see no contours or triangles. If I 3drotate and esc from that command I can then see triangles.

This is probably a simple one, but when I dimension from an edge to the tangent of a radius or circle. It always snaps to the center. How do I get the dimension to snap to the tangent point?

I basically want to convert the polylines into arcs or something. i can do this by redrawing, thats no problem, but this is a very simple drawing compared to what i normally have to deal with, this is just an example.
I am exporting to Adobe and AplhaCam, when ever I send DXF or DWG files, the Circles or arcs are segmented.
How do I make not so segmented?
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 have some polylines that mark the edge of roadway and around the curves there are arcs in the linework. How do I turn the polyline with arcs in it into a polyline with vertices, say, every .5' or so along the curve and turn the curve into a polyline? I tried the pedit and using decurve but it doesn't work well.

The arcs in the object i have drawn gets converted to lines when i mirror the object.
View 3 Replies View RelatedThe building I am working on is the shape of a jelly bean. The exterior glazing will be segmented and we are trying to make the building as dimensionally uniform as possible. IE 5'-0" Curtain Wall units. So each arc length needs to be perfectly divisible by 5'-0" and the transitions from one arc to the next must occur at a tangent point.
Eventually we will be developing the building in Revit 2013 but for now we are in ACAD 2013.
I am trying to extrude some joined polylines, arcs etc. The problem is some of them are extruding as a solid, which is what I want and some are extruding as a surface of the profile.
