I made a bunch of lines, then used the bend command to make curves where they intersected. I'm trying to put lines connecting A to C and B to D. How do I constrain the ends of the lines to the center of the curves?
View 9 RepliesI've managed to hack together some code to draw a rectangle and dimension it. Now I want to constrain it to the origin. I figure either using two dimensions from a top/side to the origin and setting the dimension as half of the other respective dimension would work. Or constraining the center point of a top/side line to be vertical/horizontal to the origin.
The problem I'm having is I do not know how to reference the origin. So until I figure out how to reference the origin point I can't use either method.

How to become able to fully constrain a sketch with an image in it? Always stalls at 1 dimension required. Try a sketch with only an imported image.
View 2 Replies View RelatedHow is this accomplished in Inventor? The 3D sketch environment seems intentionally crippled. Many of the constrains are not available, and the "include geometery" command refuses to include the origin (or any other planes and axis for that matter).

View 2 Replies View RelatedI have a sketch that Inventor changes its status between under constrained, over constrained, and fully constrained depending on dimensions (makes sense), and wether I rebuild the model (WTF?).
Steps to reproduce:
1) Open the attached .ipt file.
2) Examine Sketch11 (under Face3) It should be fully constrained.
3) Exit the sketch. Open the parameters dialog and change the value of "angle" from 45 to 60. (If you get an error message change it to 50 first, then 60. It's a work in progress.)
4) Re-examine Sketch11. It is now under constrained.
5) Exit the skecth and go to the manage tab. Click "Rebuild All".
6) Re-examine Sketch11. It is now fully constrained.
7) Scratch your head and post back with your theory.
For some reason it will not let me constrain a part to the center of gravity plains. I would like to constrain lifting lugs to the center of gravity so the model will automatically update itself. Is there anyway to make this work (using ilogic or anything)?
Why would Inventor tease me with showing me the center of gravity plains in an assembly but making them completely useless?
When I add a text to a sketch, I can constrain the rectangle to set its size, orientation and position.And I can set the text width to fit into the rectangle. But I wasn't able to set the text height to fit into the rectangle.
Am I missing something or is the fit text option doing only half the job?
Do you know how to constrain 2d cad sketch to match existing 3D model. see screenshot. Is it doable?
View 6 Replies View RelatedWhen you're working on a sketch in the part environment the status bar shows the number of constraints needed to fully constrain the sketch. For example "2 Dimensions Needed".
How do you retrieve this value using Visual Basic Net?
I have an assembly with a curved line made in a sketch, and a part with a point in the bottom.
I want to constrain the point to the curved line, but the regular Constrain options wont let me do so.
I am making an animation with Inventor Studio, so I need this constrain, so I later on in studio can manipulate it and insert the first part into the other.

I cannot select origin to constrain sketch with dimension to origin?
I selected Sketch,
expanded origin,
selected mywork plan (xy)
drew rectangle,
input dims,
right click for marking menu,
selected dimensions,
Origin is yellow,
cannot select it and then edge of rect to set dim that will center sketch on origin? Just like the videos show, but cannot select origin>
Much of our work is structures fabricated from steel plate. One of our practices is to add a note " (SK) " to the description of plates that have a detailed sketch somewhere in the fab drawing set (simple rectangular or circular plates with no additional features do not get these detailed sketches). The actual "detailed sketch" is just a dimensioned drawing view of that plate.
I've been working on automating this process so that Inventor can actually determine for the user whether or not the sketch is required. I have it in certain part templates by default. Other templates add the note automatically through iLogic when certain plate features are selected, or when the model consists of multiple part features.
This leaves one remaining case that the current set of rules can't catch - when the user creates cutouts, notches, etc. by modifying the sketch for the original extrusion. I have determined a method for catching that case, but haven't yet figured out how to program it.
What I want to do is count all of the lines, arcs, and circles in the first model sketch. If that count returns a number other than 4 lines, the note will be added. If any arcs are detected, the note will be added. If any circles are detected with lines also present, the note will be added. There may be other cases that will come up in testing that need to be covered, but I ran into an issue before I got that far. Construction geometry messes up the count - I need a way to exclude it.
Below is the test code I have so far for the counter. what techniques I can use to get construction geometry out of the count. This code doesn't include the provisions for actually adding the note yet - I'm just trying to get the counter working right first. Instead it's just displaying the total count in a message box for test purposes.
oDoc=ThisDoc.Document
oSketch=oDoc.ComponentDefinition.Sketches.Item(1)
LineCount=oSketch.Sketchlines.count
CircleCount=oSketch.SketchCircles.count
ArcCount=oSketch.SketchArcs.count
TotalCount=LineCount+CircleCount+ArcCount
MessageBox.Show("Total Count "&TotalCount, "Title")
I am trying to create a coil which from above, retains equal and thus parallel pitches whilst at the same time adheres to a semi-circular form in the cross section. You can see from the images attached that the first two revolutions are larger than the semi-circle outline.
These are the values I have used:
Cylindrical
r (t): 134.56924424045517662353735770102mm * t * 0.5
q(t): 1 deg * 360 ul * 3.0 ul * t
z(t): 10 mm * 6 ul * 0.5 ul * t * (1.5 * t) * t
tmin: 0 ul
tmax: 0.916 ul
I'm building a product configuration which includes some helical curves. I want to find out how I can change the direction of a Helical curve feature in a 3D sketch.
Variables like pitch and diameter are parameters, but the direction isn't.
I would like to use a sketch as the basis for a rectangular pattern which is set up to use the curve length for both directions of the rectangular pattern so that when I update my rectangle in a sketch, the pattern automatically adjusts to the new sketch. I have sketched a rectangle, and used one leg of the rectangle to establish the direction and length of one dimension of the array.
However, when I try and choose the Direction 2, my only options are the entire rectangle or faces- I can no longer select other and choose a single side of the rectangle.
I was able to accomplish what I wanted by using two sketches, with the second sketch simply projecting one leg from the first sketch. Using one sketch just seems inherently safer than trusting projected geometry.Is there a way to accomplish this with one sketch instead?

View 2 Replies View RelatedThe screen shot below shows three coincident constraints and a projection icon on the origin.
looks like a projection icon - what does it mean?
I want to delete the three coincident constraints. But when I delete the coincident constraints there is no Sketch origin center point (the sketch origin center point is a square-yellow dot at the x-y intersection). How to delete or move the three coincident constraints with out deleting the sketch origin center point?
After I create a sketch, how do I center it about the origin? The origin is projected, I just can't figure out how to set the sketch about it.

I have a drawing view of a part with a sketch that contains some lines. I need to pick one of the sketch lines.
I can pick a line with sketch active using the kSketchCurveLinearFilter
I have not been able to pick it from outside of sketch. Have tried using kDrawingCurveSegmentFilter to get a DrawingCurveSegment but I can not get the sketch line from the DrawingCurveSegment
I assume there is a way to get the sketch line from DrawingCurveSegment or DrawingCurveObject but have not figured it out.
Just by selecting a bend line on the flat pattern, I'd like to draw only 2 lines on a sketch (without any border projection, only points) at both ends of the bend line.
I'm sure it can be done via VBA, but don't know how to start for it.
When I use a tool such as 'move'/'select base point' in the sketch environment, I used to be able to select line midpoints.
Is this no longer possible? My constraint options seem to be fine.

I need a creative way to do something I know can be done in SW and Pro-E but as far as I know can not be done in Inventor to date
I am using the origin center line and semitry to control a box and its associated geometry and want to control the position or offset of a second box relitive to the first using a center line associated to the second box with a dimension. Problem is that the dim will only control its off set position relitive to the initial side from which the dim was placed. I.E. if the dim is placed when the CL of the second box is to the right it can not be moved to the left (what would in essence be a -dim condition) understandably Inventor does not like that but SW and Pro-E can use there little wheel and roll it down to 0 and then back up to a + dim in the opposit or in this case Left direction.
I know that I could place a dim off the interior wall of my first box geometry and associate it to the CL of the second box but the math to that may or may not be appropreatly effective in other words in condition A it may need to be 1/3 of d1 and in condition B it may need to be 2/3's of d1 or some other dimension.
I would love to be able to do this via iLogic or perhaps something to do with the placement relitive to a construction geometry utilizing a circle but so far I have not found a viable solution.
I have a basic problem but I can't seem to be able to get around it. I added an image to a sketch successfully but it cam with a yellow line around it (see attached) and I can't remove it. In the sketch properties I was able to change it's color to black to make less visible but it's still there.
Any clue as to how I can make it disappear ?
When I draw a sketch while making a dwg drawing, the lines are light green that is nearly invisible on the background color. How can I change the line color?

how to put a center line on an open ended slot. Say in the front view you can see the radius of the slot with horizontal tangents running to the end of the object; this isn't the problem. When creating the top view, you only see one hidden line indicating the arch, but the other side is just open to the end. You have no means of finding bisectors.
I've added a jpg file, looking for the center line in the top view.
