AutoCAD Inventor :: Work Axis Normal To Surface Patch
Apr 24, 2013
I have a complex surface that consists of many patches. I need to place a work axis perpendicular to one of the patches on the surface of the cheek. It could be on the interior of the patch or it could be at one of the vertices of the patch.
I keep running into a situation where I would like to be able to create an edge or a work axis at the intersection of a work plane and the surface of the part. I figured out a work around if the surface is flat, but I haven't figured out a work around for a curved surface.
How do I create work axis where work plane intersects curved surface?
Or put another way: How do I project intersection of work plane and curved surface onto the work plane in a 2D sketch?
I need to be able to draw a 2D sketch on the work plane, but get a perfectly matching projected line onto the work plane, from the curved surface, at the intersection of the curved surface and the work plane.
The attached jpg shows the intersection in question. I circled it.
I very often find that I would like to create a work plane defined by an axis and a point such that the plane is spanned by the point and the axis. But the only possible way seems to be to create a plane through the point and perpendicular to the axis.
I'm trying to get a lisp routine to flatten out ellipses, I have changing the z-coordinate to equal world ucs z ok , but can't seem to get it to re-align the normal axis zo it matches the world ucs axis.The code works fine for a circle and sould not be any different for an ellipse, yet it falls over at the (vla-put-normal) statement for the ellipse.Any clues, or is it a failure in implementation for ActiveX?
How to delete a work surface. These work surfaces were imported from an iges file which contains thousands of work surfaces. They are not associated with a part feature which can be deleted. I've developed a routine to sort through these and identify unwanted work surfaces based on their positions. The best I've been able to come up with is to make them invisible, but I'd really like to delete them completely to clean up the file. I did try to loop through and delete any surface body objects associated with the work surface but that failed.
How to make a new work plane rotated at an angle to another plane and passing through the axis of a cylinder, or one of the main axes.On the plane commands, in V2013, i don't find an option for plane at an angle
i try to make an animation. I create a cylinder and i want to rotate it by longitudinal axis. i click 'components', select the cylinder and after i click 'position' to select the axis that axis system appears in the right side of the cylinder not in the middle. If i continue whit this settings the cylinder will rotate by a circle not by his longitudinal axis. How can i move that axis sistem in the middle of the cylinder? I can drag it but can't place it exactly in the middle.
How to create a work plane that is perpendicular to a surface? I'm trying to do this so that I can "split" the object into two separate entities where the plane is.
Is there a method to add a work plane to a curved surface ? I need a construction plane adding to a curved surface to allow a sketch to to added to this plane, not sure if this is possible but the problem I have is adding a series of sketches to a curved surface to then extrude-cut for window openings.

I'm having problems creating a boundary patch on the attached model, Its a Y-Pipe joint in 3 planes that I'm attempting to split in half. I've used a silhouette curve to create a centre line in a 3d sketch then joined the ends together, however when I try to select the lines to create the boundary patch it only allows me to select some not all of the lines.
I created sheet metal parts from boundary patch. In the included files, the boundary patch is not flat, so it didnt unfold. Is there a better way doing that or a better method to create flat boundary patches ?
Is there any way I can extract the rotation of a block relative to the yz axis and xy axis. I can extract the insertion point and xy rotation but not the yz and xz.
how I can add more volume to curved object surface? Say for example I have a plastic cup.You can think of this as cylinder object ,which was the shelled out using the shell tool and then had its base sealed.
Now at certain parts, I would like to increase the thickness and then blend it the rest of the surface(may be chamfer its edges) .
At certain parts on curved surface I would like to add an extra mm, I think if the surface was flat I would just sketch the shape, then extrude it by few mm and smooth the edges by doing a chamfer
But how can this be done on surface that is curved? Or multi curved for edges?
I'm designing a press for a skateboard similar to: Rib Press
I have the board modeled: (see attached)
Now what i want to do is generate those ribs as seen in the picture.
I tried creating a block that intersected with the board and tried to split the rib at the surface, but to no avail. I think the issue has something to do with the curve of the board in two directions, but i can't seem to get it right.
if you are having trouble visualizing what i'm asking about, look at this. I want to be able to figure out the exact shape of those center ribs to print and eventually cut out of wood.
It is not possible forme to add the fil because it is to large 1.8MB how can I poste then I like to know if it is possible to extend the button flat surface diameter ø12.5 up to the shaped surface. The result should be a total solid block whit a surface shaped hole.

I am a beginner when a extrude a feature and select a part surface for new sketch now i want is to offset that surface but i can,t there is + sign with mouse icon and something like fully constrained is written in down the window.
I use RocTek for cut/fil calculations, but the program is old and basic, I'm trying to transition to Civil 3D 2012 right now. Typically I create "no work zones" around my building footprints, so that I can do a more detailed take-off in those areas for over-excavations and that sort of thing. Right now I'm using Civil 3D to create an existing surface, a proposed surface, and then a volume from between the two. I thought if I just traced my proposed contours over the existing within the building footprint that I would get what I was looking for. However, analysis of the cut/fill volume shows that there are still some changes being made around the edges of the building.
Is there a specific way to make a proposed surface, but leave parts of the existing surface untouched?
See attached photo. The upper middle portion of the screen is where the building is (forgot to turn on layer).
this thread confirms that Autodesk broke the surface transparency functionality in 2013. I imagine by the lack of response to the original thread that this is either a little used or not well published feature....

I recently upgraded to Civil 3D 2013 and now all of my "Create Surface" commands do not work. I get the message " _AeccCreateSurfaceGridFromDEM Unknown command "AECCCREATESURFACEGRIDFROMDEM".
Why, when I create a plane, I cannot 'flip normal'? There is nothing in the RMB click for it...and I am not sure why. Still there in part...just not assembly. Was it ever?
Alternatively, when I create a plane, is there a way to create with the normal in a direction of my choosing? Never tried to figure this one out cause I always had flip normal...
I have a cylinder on top of a curved surface; I want to make the cylinder land adaptively to the surface, so I projected the circular face of the cylinder in the surface, which ended up being a 3D sketch. I tried to loft a solid between both curves, but it always gives me errors. Some examples are:The attempted operation did not produce a meaningful result. Try with different inputs.Multiple disjoint loops found in a profile section.
I have had success when trying to do the same thing with curved surfaces in two dimensions only (e.g. extruding a 2D curve), but I think the error is produced since the curved face I am trying to use belongs to an elipsiod.
how incredible it is that Inventor still does not have a functional normal cut option for sheet metal like Solidworks and Solidedge have long had and I agree. I realize that there are the standard workflows like using derive and thicken to get around this problem. However, for those interested, there is a way to make a normal cut (for laser/cnc) directly in the sheet metal part in many cases. It involves using a sketch to split a face and then using the resulting profile for a thicker/cut feature. I'm always interested in any other methods out there for obtaining normal cuts in complex sheet metal (for a clean dxf export). By the way, Autodesk, do you actually not have any plans of ever adding functionality in this area?
