I draw 3D curved handrail, mainly just rectangular because i import the geometry in to Alphacam and run tool paths down them, but i keep getting faced with the problem of the twisting of a solid when sweeping along a spline or a 3D poly!

I'm having a problem sweeping a curved object over a spline. The object will sweep over a straight line...but not on the spline. I keep getting "unable to sweep object(s)" in the command line. I could be doing it all wrong... I've attached the file.
View 9 Replies View RelatedLet's say I have a 3D polyline, which I turn into a spline. I then want to determine how closely the original polyline and spline follow each other. How I can check this programmatically? The concern is to find the maximum deviation and its location.
Howto be able to run the check on other types of objects as well: arc, polylines etc.
what the best way to project a spline onto a edit poly 3d surface. i would like to maintain adjustability of the spline and have it morph an instance projection onto the surface if possible.

I have created a big spline. When I tried to "Convert to poly", it doesn't work. Usually, as result, the spline appears with a filled. In my case, the spline disappears. I thought it might be because the spline is not closed, but it is correct.
Is there a way to extract the WHITE edges of this Editable Poly as Spline Shapes? Then I could use the Surface modifier to convert it to a Patch object.
I know there is a "Create Shape From Selection" button on in the Editable Poly dialog. But this gives me the ORANGE lines from the control cage, not the smooth lines on the subdivided object.
Looking for a lisp to convert a poly face mesh to a solid.
View 1 Replies View RelatedAs you can see, the nature of my model forbids me from making a 3D solid using LOFT.
The top surface is consisted of 3D polyline and arc, which if "joined" will be become a spline.
The bottom surface can easily be joined into polyline.
If I loft the top and bottom, it'll only give me a LOFTED Surface, which is not I want (wanted a 3D solid).
I'm trying to make this street a solid so that I can break it up. I've tried numerous ways but couldn't find a way to do it.
[URL] is what i have, I want to somewhat combine those both to create a solid.
i'm applying an extrude modifier to a simple spline shape, and i am accustomed to the extrude modifier generating a solid 3d object in the shape of the spline, if the spline is a closed shape.
however, in this case, the extrude modifier is generating just a 3d outline based on the spline's shape...
i can't figure out why i'm not getting a solid 3d object since the spline is closed (i checked all the vertices).
file is attached (the spline in question is named "upper side section")

I'm trying to create an external involute spline (ANSI B92.2M) Fillet Root Side Fit 26.9mm x 1 mm x 26 teeth x 38 mm long using the spline generator with Inventor 2012. I created a test shaft"M-182-AMA.ipt" that is Ø26.9 mm x 38 mm long with 1 mm radius on each end of shaft.
I use the following steps:
1. After creating component "M-182-AMA.ipt" I select Design tab>>Power Transmission>>Involute Spline.
2. A window appears that has the caption "Involute Splines Connection Generator".In the Dimensions section I choose "Splines Type: ANSI B92.2M - 37.5 deg, Fillet Root, Side Fit, 26 x 1.00 x 38 x 5H/5h" and change the Length to 38 mm.
3. In the Shaft Groove section I use Create new, and I push the Reference 1 button that turns blue, I then select the od feature from the model and I get an error(see attached pic "error1.jpg).
I changed the 26.9mm od to be 27mm and it still gave me the error.

My issue right now that I can't seem to find an answer to is it seems that when a certain engineer in my office opens a drawing at her computer and saves it, the drawing is slightly "twisted" i guess you could say.
I have a fix to this issue, for example, I use DVIEW and change the points to 0,0,0 and 0,0,1. Which works just fine and fixes it. But for some strange reason it seems like after she opens the file and saves it, the target point usually ends up as something like 1.35454,2.5664721,0.0000076 And I know that the last coordinate is what causes the problem.
I'm just curious if there may be a variable or something set on her computer that would keep causing that to happen when she opens a drawing so that I can set it back to default and eliminate the time spent on running the DVIEW command on every drawing that she opens.
My model is ready for the rigging. But my model is a little heavy in poly-count. I can rig it now but at the time of animation i know it will be a problem while animating it. It will lag while moving its controls. I have seen people animating with low mesh and while rendering they use high mesh. Do, i have to create a low poly version of my model?. If yes, Then i have to paint weight twice. low poly one and the high poly one.

It is the basic shape of the Magnum sticks, but it is tricky because it has a 140 diameter taper, from the top of the jig to the bottom. I am trying to make the circle attached to the shape of the stick, and the Sweep the circle around the shape. But when I try to sweep it around, it says "The sweep results in a self-intersecting circle". I am using AutoCAD 2012.
P.S. I have attached the .dwg file so that it makes more sense.
I am modeling an ASME pressure vessel with a 2:1 semi elliptical head upon which there must be a couple of lines of .375" trace tubing. I created a 3dpolyine that is the center line of this tubing, and joined all the segments into one so as to be able to sweep the whole thing and make one solid of the tubing run, but it simply will not sweep. I get a message this it is "unable to sweep the selected object." If I break the 3dpolyline, I can sweep parts of it, but the more complex the line segment, I again get the error message. I have attached a copy of the tubing centerlines.
The one on the left is the joined 3dpolyline, the one on the right is the 3dpolylines unjoined. (These were achieved using an intersection command of a rotated surface--the head profile--and an extruded surface--the tube tracing plan layout.) I have done this before, but only with the unjoined 3dpolyline, as in the right-hand example, but that is very time consuming as each segment must be swept. But I recently acquired a third-party LISP routine that joins the 3dpolylines into one. I'm thinking there must be a limitation on data of the 3dpolyline preventing the sweep, and wondering if there is a setting or system variable that will allow the more complex 3dpolyline to be swept.
How to use sweep to successfully put threads in a hole. Attached is the drawing with a helical coil and an object in two different orientations (A and B). To the right of that, you can see the path they took for each. The object rotated from the original position before following the path. Tried changing the position of the object to sweep, but either it sweeps it 180 degrees from what it is already doing (still wrong) or the program says it is invalid and won't do anything till I put it back in the original rotational position and try again.

I am trying to create a tube by sweeping a circle along a spline. I read many of the previous discussion threads on the topic but I still have some issues.
I first created my spline and transformed it in a polyline (some people recommended to do it). Then I created the circle. Finally I sweep the circle along the path.
The issues are the following:
1) when I look at the tube using the 2D wireframe mode, I can see that the primitives are not completely regular. In some points there are weird intersections and I don't know how I can fix them.
2) I hoped the tube was solid. However, when I exported (as .IGS) it and see in another program, I realized that it has only two circular caps at the extremities of the tube, but inside it is hollow.
I tried to transform it in solid or mesh or whatever, but it always gives me an error, saying that the object cannot be converted.
I'm trying to make a part of different tubes by sweeping circles along lines. However one side of the part joins correctly, but other not. I'ill add photos of correct smooth join and uncorrencly unsmooth.

How do fix this without really having to reskin the whole model
We have this need to have all of the solids in a drawing to be placed in the "solid" layer.
Sometimes folks are drafting lines to develop these solids, and keeping the lines on the "solid" layer, rather than moving them to another layer, or deleting them altogether.
I could get folks to run this command before leaving the drawing.
I'm thinking something along the lines of:
Select all entities that are on the solids layer that are not solids.
If nil, great, do nothing.
If entities are selected, let me do something with them.
I'm hoping the following can be modified ever so slightly.
(setq non_solid (ssget "X" (list (cons 0 "3DSOLID")(cons 8 "solid"))))
I'm trying to split a single solid body into 2 solid bodies. The problem is that the body I'm trying to split consists of two separate pieces. I can split a body when it is a single piece no problem, but I'm having the problem when the two pieces are not joined at all.
When I try and split it on the origin plane it gives this error:
"Creating parting line failed. Could not build this Split"
When I try and split it on a work plane lying on one of the pieces it gives this error:
"Creating parting line failed. Modeling failure in ASM. Redefine inputs."
Or, another variation on this erorr:
"Creating parting line failed. Split feature could not create two bodies. Change the Split Tool so that split feature can create two bodies."
I have a.3ds file imported into Civil 3d. The object imported as a polymesh in Civil 3d. I need the solid 3d object to do some edit like slice or union and subtract.
The question is "How can I import .3ds into Civil 3d as a solid objects or hoe can i convert polymesh to solid?"
I have finally created the shell of the complex surface that you see. This is only a section of the part because I cannot show the whole thing for proprietary reasons. I formed solid surfaces using the network command. The propblem is that it will not convert to a solid because the surface seams are not "water tight." When the network command created the solid surfaces, the surface seams do not exactly match the lines so there are gaps in all the seams. I have tried blending, patching, etc. and nothing works. how to convert this to a solid without losing the outlines and the shape?
