AutoCad :: Conical Roof - Helical Radius Along Face Of Cone
Nov 11, 2011
I have started a project and have a somewhat unusual condition. I have a structure with a Conical Roof. We are putting a parapet around this roof. With the parapet, we are also going to create 4 individual structures that direct water/rain flow to scuppers that will be fabricated into the parapet. Below is a sketch of our condition. How to get the shape of a line that follows the face of a cone. Obviously, this line is not projected to the center of the cone, so it is not just a straight line. I am imagining either a radial cut piece, or a complex/multiple radial cut piece. I don't really know how to put it into words exactly.... Take a look at the sketch.
I want to engrave the text 'TEST' all the way around this clonal object. When I use the emboss tool, selecting the option 'wrap to face,' it gives me an error message that the "face selected is not tangent to the profile plane."
I am using a work plane that is offset from the XY plane. I included a screen shot and the file that I am using (Inv. 2014)
I would like to know whether it is possible (and how) to trim a wall that was generated from mass face to a roof (also generated from face mass) or/and make a horizontal hole in it. The wall itself is not straight or curved, it shifts outwards from the building from base to top (still in an elevation it looks like rectangle).
1.How can I edit the roof in attached dwg to be like in attached jpg?
One option I think it would be to convert it to roof slab.
What is the disadvantage (if any) to convert ia roof to roof slab?
Can I create it in other way ?
2. In section 2, the first floor walls ends in 90 degrees angle at the roof. Can the walls be edited so that the joint line with the roof follow the roof slope?
I am currently working on a home where i need to have a single slanted roof go across the perimeter of the home to form a roof. But, i have run into the issue of not being able to connect the circled area(see attached) Is it possible to connect those separate roofs and if so how?
I am creating a fan wheel (see attached). The fan blade needs to be extruded to the inside surface of a 2 piece cone assembly. To make it even more difficult, the inner portion of the blade needs to be cut at an angle so that the extrusion ends at the cones. See attached pdf reference sketch. The result for the flat pattern blade edge should be two parabolic curves.
I've attached the file (Inventor 2013). The sketch shown is a raised lip I'd like to have around a future opening. I actually want that sketch to wrap all the way around the body, but taper down to 0 in the rear as there are to be hinge plates. This is going to be a grill/smoker and there needs to be a 3/8" raised lip at the future seam of the top and bottom. Shown in the model is just the top portion.
how to edit a solid with opening a hole only one face and deleting an another face..
I added a drawing file which has a coloured face solid,I put a circle on blue face and making a hole on this face,and I want to delete red face without exploding solid,after all this I want to mesh this solid with maximum 25 units.
All I need to do is merge a circular face to a flat face, so both faces become one continuous face. Is this possible at all?
I have a attached a screenshot to show what I mean. Face 1 needs to be merged with face 2. This is so if I constrain anything to that face it will constrain to the entire face and not either the circular face OR the flat face.
Is there any way / trick to wrap a 2D sketch to a non-flat/cylindrical/conical face? See attached part. I'd like wrap the lines in Sketch2 to the ring's outer face in order to get a proper path for "engraving". I see no other way to get a proper path for sweep, because project along vector won't work.
I need a conical spring that can change in pitch as it tapers. Basically the spring starts in a compression style and tapers down to an expasion style. The CNC spring machines are capable to produce it, but am I able to, through Inventor? If not when will we have this feature capability?
I have created a 3D model of a helical gear. The process followed was to use the profile of one tooth, which by the way is a true involute shape, then displace that profile and rotate it the amount needed to equal the face width of the gear and to match the helix angle. There is also a profile located at the midpoint of the gear. The profiles are all closed polylines.
I then used the LOFT command to create a solid tooth. It looks exactly like it should. I tried to use the SWEEP command but that rotates the profile 90 deg. from the path. Extrude won't work because the path is a 3D line in space.
I then invoked the POLAR array and put 28 teeth around the center of the gear. That too looks exactly as I would expect it to.
BUT - when I try to UNION the 28 teeth into one solid, AuotoCAD 2013 stops working. And that occurs the moment the cursor touchs any part of any individual tooth. If I try to UNION the array by dragging a window over it, it stops when the window gets about halfway over the model.

I have a sheetmetal assembly with helical shaped parts. I need to place about 50 little brackets and some corresponding rollers along the length of these helical pieces. The spacing is even so a pattern would be perfect, except I don't know how to get it to follow the shape of the part. The brackets are located to slots in the helical parts which were made with a rectangular pattern in the unfolded state. I tried to do a "feature pattern select" but it only saw the rectangular pattern as it is in the unfolded state (a straight line). I then gave up on patterns and started working on manually mating them into place but realized that the geometry of the slot was distorted (theory) and didn't leave me with any useable surfaces.
Having problems creating a helical truss/ shape. Ive managed to get a simple spline spiral. Which I'm still not 100 percent happy with. But it will suffice for right now.Now one of my problems is extruding, and offsetting. I'm pretty ok at 3d modelling, but when it comes to complex shapes i fall flat on my face. Ive including a dwg that shows a plan view of the structure, as well as my 3d spine. the small circles are the truss cords. Its a 16" flat truss, ran parallel with another to create a spiral ribbon.
The plan view is from the designer, I've noticed but maybe its not true... their helix doesn't seem consistent. I know im leaving a lot of info out.
I'm trying to create a rather oddly shaped stair stringer. It will have several radii, and direction of curves. The screenshot below isn't exactly what its going to look like - I just drew a quick spline and extruded it into a surface to show what I'm trying to accomplish. I need to "cut" the sufrace to reflect the height of the stringer (will be 16") and to follow its pitch.
I have the German version of Inventor 2014, so some translations may be different.
I want to project a text on a sketch onto a conical surface. The error message is that the chosen surface wasn't tangential to the profile plane. I found no way to rotate the plane.
How do I project my profile onto the conical surface or How do I make the profile plane tangential to the conical surface?
I am drawing a fan wheel. The fan blade is curved intersects the shroud, consisting of two cones. I do not know how to trim the blade to the cones. I tried to "split" the blade at the cones and then "delete face" but then the "Go to flat pattern" section on the ribbon is missing. If I suppress the "delete face" feature the "Go to flat pattern" re-appears.
I am trying to recreate and 3D model the impeller of a heartmate II LVAD (URL....) but I am having problems with the sweep along the helical path. The profile is the vertical line and the path is the helix. I want to use a surface output for now. I had to use Solidworks to generate a variable pitch helix and import into Inventor.
When showing a gear in an inventor drawing they look good, but showing a helical gear SUCKS! The display, I realize, is very realistic to what you would see if you held the gear in front of you at this view point or that.
Problem is, I put a helical gear drawing on the shop floor and they machinist wonder why I have two rows of teeth on the gear (since it shows the front face and the helix'd gear teeth).
I created a 2D planar sketch, now I need to create a 3D sketch and Helical curves, but as I enter into the 3D sketch mode, I cannot perform any functions, all my tool bar options are grayed out?
I'm trying to build an assembly with conical rollers rolling on a cylindrical support. Refer to the attached sketch. I'd like to be able to constrain the conical faces of the roller to the cylindrical surface of the support. It doesn't seem to be possible to do that in Inventor; or, more accurately, it's not possible to put a tangential constraint on both conical faces at the same time. The first tangential constraint causes the part to place a generatrix line parallel to the axis of the cylinder. (I had to look up what generatrix means, too.) So it's not possible to make the second tangential constraint.
How I can do this? Just in case that's not difficult enough, the reason I'm doing this is because, ultimately, the support will not be a plain cylinder but actually a tube that also curves. It's the behaviour of the roller through various curves on the support tube that I ultimately want to model, but I have no hope of doing that if I can't even get the roller constrained onto a plain cylinder.
