AutoCAD Inventor :: Lines In 3D Sketches Change Direction?
Aug 2, 2012
I've created associative 3D sketches to use as trajectories for sweeps. I will often have to use one line extending from the end of another line. I make the two lines colinear. But when the model changes, sometimes one line will change direction and cause an overlapping condition which makes the sweep fail.
Any way to keep it from happening? Ideally, I'd create one line that extended, but you can't constrain a line to a point, only an endpoint to a point. I'm attaching the model.

I'm having issues when I create sketches using the line tool. I should be seeing constraints as I create them and a green dot when the object is closed. This is not the case however, and when i attempt to extrude or offset the sketch I can only select individual lines.

When we derive sketch from another piece, this is inserted in a fixed location and orientation in our piece. There any way to make changes to this sketch derivative. For example change its location and orientation to fit the geometry created by the sketches of our piece.

I am trying to miter the joints in an assembly being used for iCopy. Currently there is a driver sketch which has lines bisecting each corner at 45 degrees. However, what happens is that when the top line of the sketch is dragged across the bottom line of the sketch or the left line is dragged across the right so that the rectangle inverts itself, the line no longer bisects the angle. See the attached pictures for details.
This sketch shown is a master sketch used to drive part length and end details in an assembly. The blue lines are extruded into surfaces which define the parts using a "Between two planes" extrusion.
The sketch is unconstrained in four ways: overall width, overall height, vertical and horizontal movement. This is done to accomodate its use in as a flexible assembly in an iCopy command. What happens is that when the user applies the iCopy points from the wrong side of a sketch plane in the parent assembly, the sketch flips itself and resizes the assembly but the miters are inverted.

I have a drawing of a stone railing section and I have to change direction in the run direction of the baluster panel. Is there a way that I can move the details without changing th Y direction of the details. Please refer to the attached CAD file for details. I am trying to avoid having to redesign the panels if possible. railing detail.dwg

i am doing a simple project making a survey plot for a piece of land that will be broken into subdivision. all measurements are of my starting point. after plotting the starting point i try to draw line that is 113 feet long and at a bearing of N 5d W i have no problem entering this data but when i hit enter it draws a straight line. now i know 5 degrees is much of an angle so i thought maybe it just looked straight and tried to plot the next point which was 542 feet from the last point at a bearing of N 39d E but once again after i put the info in and hit enter or space it would plot a line of the proper length but vertical, not the proper angle i need it at. here is how i would put in the info:
first i choose the lne command and choose my "beginning point" as that starting point for my line then i type 113<N 5d W for the length and direction and hit enter. when i do this it plots a vertical line of the proper length but wrong angle. what am i doing wrong? i have ortho set to off and idk what else to mess with

I can't seem to remove col-erase lines from my sketches in Photoshop.I have Photoshop CS5 and my OS is Windows 7
1) Scan drawing and open in Photoshop
2) Go to channels and remove the other colours than the colour of the pencil (ex. remove green and blue if the colour is red)
3) Change the mode to Grayscale (and back to RGB/CMYK if you want to colour it)
My problem is.. that it only goes halfway. It looks fine until step three. When I change it to Grayscale, the col-erase lines come back, just in B/W and I need to erase them anyway.

If you have a collection of balloons you can make them go horizontal or vertical. Is there any way you can make the balloons to go in a 45° angle?

What instances is it necessary to combine 3d sketches with 2d sketches, I have used this combination a few times where I have to build rectangular frames then apply frame generator to the sketches to construct the frame members. I was told when I originally had training on Inventor 2013 that 3d sketches should be avoided where possible.

I have the following (somewhat philosophical) question: what is the concept of assembly sketches? As far as I can see (and what I use it for) is the following: an element of my design can be constructed from several parts, which are first machined with some margins, interfaces for welding, etc. Then they are mounted/welded/brazed together, and the final piece is constructed by post-machining the mounted (welded/brased/etc) assembly. Assembly sketches drive these features.
When I first got in contact with assembly sketches, I believed they can be used to positioning parts in the assembly: create a sketch, very easily and quickly draw lines/points/etc which serve as anchor points for the parts, and then constrain the parts to these lines/points/etc. But this does not work - whereas I would find it sometimes useful.

I've been making a model plane model in inventor 2012 from imported IGES geometry, and Realised that my sketches were not assigned to any part (and thus can't be lofted). Is there any way of moving the sketches to the newly created part without redrawing everything? I've tried dragging and dropping because it seemed to make sense, but alas, that had no success.

Quite often we cretae schematic line drawings for clients approval before creating full 3D models for production. Is it possible to achieve this in Inventor and maybe go on to use the sketches as a master filoe to drive the design? Or should I continue to get approval based in AutoCAD and then switch over to Inventor?

I have been trying to create an ipart. Once the ipart is created i am un-able to edit the sketches of features with issues.
I need to modify a sketch and to create an alternate sketch (suppress/unsuppress) but get an error message when i try to edit the sketch.

I have created a frame using the frame generator that I need to document. It is created using about 5 sketches. The sketches are part of their own .ipt file. Now I would like to document the frame but cannot figure out how to do it. I have tried creating sections of the frame but I cannot snap to points of interest on the frame, such as where two pipes meet, when dimensioning. How do I document the sketches?

I'm trying to employ a technique that I've used with SolidWorks. I'm working on a project with several engineers doing design work on a large assembly. The way I've seen this handled in a SolidWorks shop is to create a master assembly with sketches on the principal planes that define envelopes for sub assemblies, interface dimensions, and so on. Each engineer can have the master assembly in their sub assembly, as a guide. Where I've used this before, it has worked with integrating the sub assemblies later on.
Here's the complication: There are several different "families" of the product that require different dimensions on the master sketches. What I had hoped to do in Inventor was use view representations or level of detail representation to control the visibility of these "families" of master sketches. When an engineer includes the master assembly in his sub assembly he could then easily turn on the "family" he wants to see. But it turns out that neither view representations nor level of detail representations influence the visibility of sketches. (Position representations don't, either.) Sketches are either visible or not visible, regardless of which representation you're in.
Is there some way I can control the visibility of sketches, in groups?

we very often create parts/assemblies using skeletal sketches, problem we encounter is that when we use the copy command in the components area on the ribbon.
The problem we have is that when we open the new assembly and components they are still looking at the original skeletal sketch. is there anyway to copy the orginal skeletal sketch to a new one and the new parts look at this upon using the copy.
At present what we do is make a copy and rename the original file. Then open the assembly and it looks for the original skeletal sketch, so we point it at the new skeletal sketch.
This is not an issue when we have a couple of parts in an assembly but if you have a lot of parts in the assembly it si very time consuming.

In the course of working up a tooling proposal, I attempted to replicate a 3D part from a customer print. While doing so, I noticed that 3D Sketch will not, under any circumstances that I can find, allow an angular dimension between a line and a plane. The customer print has two pipes projecting at odd angles from a base flange, one of which has an elbow. The print lists datum dimensions for the open pipe ends and the elbow, and gives vertical and horizontal angular dimensions to define the directions in which the pipes emerge from the flange. I have defined these three datum points in 3D space without any trouble, but Inventor 2013 will not allow me to define an angle between these sketchlines and the XZ and YZ origin planes, or between these sketchlines and the faces of the flange base I've constructed.
I am currently waiting on a proper 3D CAD model from the customer, and I'm considering longhand trigonometric calculations to place these lines properly, but I find it very hard to believe that Inventor is incapable of constraining a line to lie along what is effectively the surface of a cone.

i am working on an ipart. I have a spreadsheet with all the data and used the first line to creat the first part.
no problem.
i can add the remaining information to the table from the spreadsheet.
When returning to the drawing environment i can select a few parts that work and there are many more with "issues". So i move the first offending part select it and try to edit it. ( i know what i have to do to the sketch if i could just get into it) Also i have suppressed a sketch and inserted a new slightly different version (the issue) but, after getting out, i am un-able to edit this new sketch either.
the message comes back and says i cannot edit this part, and then....
unable to prepare the part for edit, updating your part is required to all the edit, update now?

I am trying to render some images and video of a design I've been working on.
This isn't an absolute necessity, but I would like to have my companys product and logo displayed on the monitor in the design. If you look at the screenshot what I'm trying to describe should come clear.
These images were just dropped into a sketch on the face of these two monitors.
When I go to render, the sketch image does not appear. It just renders the default face color of the part.
Is there something I'm missing?

As I learn more about Inventor I have been doing more and more skeletal modeling. It work well for what we build here. But the biggest problem is the visibility of all the workplans and sketches. I know of the buttons to turn them on and off, but everytime I make a sketch and edit a sketch, inventor default turns all of them on. Making it impossible to see what you are working in the assembly enviroment. Not only that, it bogs down my machine untill I turn them off. Same goes for workplanes, if I create one the rest appear.

In my section view, Get Model Sketches is inactive (greyed out; see attached).
It was OK up until recently, but now it would not show any sketches no matter what I try to do.
I would hate to recreate the view again.

I'm working with a series of 3D sketches. Some sketches must remain visible as reference. While creating the sketches, the dimension call-outs grow too distracting from the linear sketches. Is it possible to hide, or toggle off/on the dimensions while leaving the sketch geometry visible?
