Working on Acad2012 3d Civil. I draw a circle of 4000' radius and another one of 2000' radius. I put a tangent line between the two circles and I do see the tangent symbol but when I zoom in real close, it's not. So now I can't trim the excess radius of the two circle. I do have a trim line pasted the two supposedly tangent points. Is this a CAD issue or is their a variable to change that actually makes the lines tangent.
View 8 RepliesI need to lable the delta of a PI in an alignment where one segment is an arc and the following is a non-tangent line.
Geometry points don't offer delta and Tangent Intersections won't label at PCs and PTs.
Is there an expression that can be used?

I noticed the tangent snap stops at the end of the arc but one can still place a line beyond the end of the arc, thus no longer tangent.

i want to snap this line to where it would be at a tangent to the arc (as right), but as you see (left) when i hover with TAN snap it picks a tangent from the pick point, not from object's orientation.
at the moment i construct a tangent by rotating a copy of my line by 90°, and snapping it to centre of the arc. then extend out past arc, where the intersection is now the point i originally wanted to pick. make sense? gotta be a better way!

View 4 Replies View RelatedI’ve an already drawn inclined line from a fixed point (saypoint (0,2) on Y-axis). The inclination is also fixed (say 150 tothe horizontal). My objective is to draw a circle with one quadrant at a fixedpoint (say point (1,0) on X-axis), so that, the line becomes a perfect tangentto the circle. The diameter of the circle may vary to make the line perfecttangent to the circle.

View 2 Replies View RelatedWhen inserting a DIMRADIUS in older versions of AutoCAD, the extent of the radius dim used to automatically stop at the tangent point along an arc. However, now in ACAD 2013 (and possibly other recent versions), a red 'extension' line is carried on beyond the tangent point, which I don't want. Is there a toggle that switches this off so that the radius dim stops wholly at the tangent point as before?
I've tried using endpoint snap to stop the dim at the tangent point, but the radius dimesion text is then placed on the outside of the curve rather than the inside where I want it.
I am trying to create a dimension in an .idw that goes from a line to the tangent of the outer diameter. I have tried several approaches but I cannot get it to work. Essentially I am trying to replicate a drawing which was created in Solidworks but I am having trouble with this dimension.

View 1 Replies View RelatedWe have a need to select a tangent line/polyline etc and then select two other points we would then like to have the program draw an arc through the two points and yet still be tangent to the initial line/polyline that we picked. We don't care what the radius is as we believe there is only one solution anyway. It would be wonderful if we could just use the Arc command and select start>Second Point> then just use the Tangent Osnap but I guess that is out of the question :-)
The only code that I have come across that even resembles this only allows for one point not two (STILL VERY HANDY AND VERY SLICK)

i have problem with the Application option settings for sketch enviroment: When i draw a line in the sketch, i am not able to do the "click hold for a tangent arc to the representing line" it just starts a new straight line.
I know it has something to do with the settings, but can figure out what the correct settings are...
Why can't Inventor constrain an ellipsoidal contour with a line? We have pressure cylinders which uses a 2:1 ellipse. These cylinder get welded to a base stand fixture. The surface of the ellipse nestles in between contact points of the base stand, in this case lines of geometry. Yet Inventor can't constrain them as such. Any good workflow (at the assembly level) so that we don't have to ground components and use the Analyze Interference tool to make sure we are right on the surfaces? I don't understand why it will work for a cylindrical surface but not an elliptical surface.

View 1 Replies View RelatedI believe that I need to define a custom Expression and then add it to the Label Style of a Tangent Intersection.
1) I'd like to add the max superelevation (e max) value of a curve to the label. This might be impossible.
2) I'd also like to add the design speed value to the label as well. This could be pulled from that value set in the design criteria of the alignment creation.
I created a horizontal alignment from objects and upon importing it c3d seems to have taken liberty to arrange the lines in order it sees fit. Is there a way to rearrange the alignment tangent and curves and change their direction?

I received a drawing where I have to add Bearings to an alignment and Right-of-Way lines. I have a Line Label Style that it works for that purpose. These new bearings are "Alignment Tangent Labels" and we need them to be "MTexts"
Select & explode once, and you get "Block Reference"
Select & explode again, and you get "MText"
Once that is done, unfortunatly, I get "3D Faces" objects in the background. Invisible on the drawing, but visible on paper once we plot them. The only way to remove them is by selecting around the new MText until I click on one, then, right-click, Select simnilar, Delete!
Is there any way to prevent that to speed up the process???
How to get a tangent bearing or radial bearing to show up in the legal description writer? All I can get are their opposites. Is there some code that I can add that will swap their direction (say NE for a SW)?
The convention out here (OR/WA) is to show a radial bearing (from the PC to the radius point) or a tangent bearing (into the beginning of a curve) for any non-tangent curves. So far, I haven't been able to figure out how to do this automatically.
Also, any good guide or list of variables for using the Parcel Reporting for legal descriptions in c3d? I really want to know what ALL the different pieces of data are that I can use in the legal writer, and how to manipulate them.
Heres the issue;
I created my main corridor which is a 4 lane arterial with ditching on both sides targeted to my prelim surface. On my main corridor i have several intersections and approaches which i created intersections for and set the targets so they are correct, i also created secondary roads for all intersections. Now that it is visually correct there is a few things i would like to do.
1) Combine all intersections to my main corridor and create surface for adjusted volumes.
2) Raise combined corridor and intersections to adjust cuts / fills so that all attached intersection and adjacent corridors adjust with the main corridor.
Do i have to go to my main corridor profile and move each curve and tangent separately, then check all other profiles and intersection to insure everything has been adjusted?

I am looking to draw my pipe with a thicker appearance than the typical line of width "0". Our storm pipes are usually drawn with this so as to stand out from other utilities. If the pipe is represented by a polyline, I have usually adjusted the "Width" or "Global Width" value to my liking. With pipe objects, it seems more complicated. I have searched the settings, and the closest thing that I could find was the Lineweight property, but that appears to have no effect on the line thickness in the CAD drawing.

I needed to remove a feature line that I used as a break line when creating a surface. When I removed the feature line from the definition of the surface, the grading did not change. It appears the points created by the feature line remain which is why grading didn't change. The only work around was to delete these points.
I noticed the same thing happens when I removed the surface boundary and inserted a new boundary. why these points remain and how to remove when I delete boundary and feature line from surface?
I have a line or a pline segment and i want to start a line from a point laying there and go perpendicular outwards. Is there a way to do it with tracking?
Yes, i saw the command draw line at an angle but i find it a little bit complicated for a simple task like that. I am sure autodesk have a simplest solution about that.
If i am already at the draw line mode and i can easy catch the tracking perpendicular to previous segment but if i want to start from another line and go perpendicular i cannot make the tracking work.
