Hi,

That's ok, it's great that you find CadTools useful.

The "Circle at Point" option creates a Point Object id you set the radius to 0 (Zero). If you look closely ta the radius input box there is a "zero=> point" information.

God!!! How could not I see this?
And, now that I see this, I feel truly embarrassed for assuming that you omitted such an important feature for some reason. :-[

I am extremely sorry Sir, but let me once again say that you really are a life saver.

I've looked in the helpfile and noticed that this information is missing, this will be fixed.

Thank you Sir, that's going be extremely helpful.

While developing CadTools my main goal is to design commands in such way that it useful to a majority of users. This may result in a workflow with several steps to get the final result.

I totally agree. Figuring out an efficient workflow to achieve a certain goal maybe tricky at times, BUT once you figure it out, it pays-off for the initial effort pretty soon, as it saves a lot of time and energy, especially when the task is repetitive.

I have developed my own workflows and benefitted from this approach almost every day since last 11 months. I found CadTools in Oct-2021 (and I am glad I did), when I joined my new job, and it has literally changed my working style.

CadTools General / Import Points using Draw from Coordinates Command
« Last post by Yasir Aman on September 16, 2022, 09:45:13 AM »
Good Day Sir,

The Draw from Coordinates command is "almost" perfect. The only option missing is to draw Plain AutoCAD Point Objects at desired coordinates.

I am sure you must have some valid reason for this decision, but I wonder what that reason might be, because in my personal experience the Point Object is the most common object used to process survey data.

Of course we can use a block object that consists of only one point to draw from coordinates and then explode it to get the desired result. HOWEVER, creating a block every time one needs to import data for a new project/drawing soon becomes annoying and time consuming.

Two Humble Suggestions:

First of all, I completely understand that this software is NOT your full-time job or commercial activity, therefore, I do not expect you to completely agree with me and/or follow my suggestions.

That being said, it will be extremely beneficial for users like me to have any one of the following;
  • A separate Import Points Command inside the "Points/Circles" section, which can import Points and include options to draw Point ID, XY Coordinates, Z elevation, Description, etc. (whichever the user needs) on the same layer or separate layers. It will also be helpful if the user can control the Size (text height), Rotation, and position of the text items - e.g. Horizontal and Vertical offset from insertion coordinate.
[OR]
  • Just an option to draw Points in the existing Draw from Coordinates command. The user can import points using this command and can then annotate Elevation using the Annotate Point Elevation command that is already available in the "Points/Circles" section.
I apologize for my lengthy sentences (and probably bad grammar) as English is not my primary language and I am extremely poor at expressing myself using fewer words.  :-[

Lastly, I wish I could emphasize enough that you are doing an amazing service to the CAD & Engineering community by sharing your skills in the shape of this amazing utility. Your time and effort is highly appreciated, and makes countless lives easier - EVERY SINGLE DAY.

Thank you and stay blessed!

Hi!
Yes that os possible.
  • First you create a new surface (or import triangles from graphics, using the import surface in Edit/View form).
  • Then convert your 2DPolyline to 3Dpolyline using CadTools Convert command.
  • Finally you use "Edit/View" command, load your surface and then use the drape command.
This procedure will drop the polyline onto the triangles and insert a vertex at every crossing with a triangle leg. As an option you can drape only original line vertices (useful if you creating a drainage pipe)

If your 2DPolyline contain arcs they will be converted to 3Dline elements due to the fact that a 3Dpolyline only can contain straight line elements. You can use the Setting "Chord height" in the General tab to manipulate the accuracy (default value is 0,01, a lower value will increase the accuracy)

CadTools General / Project 2D polylines to surface
« Last post by JensM on August 19, 2022, 12:26:43 PM »
Hi,

I'm trying to find a way to convert multiple 2D polylines to 3D polylines.
The height of 3D polylines should be determined on the basis of a previously made surface.
Is this possible with CadTools?

Thanks!

Civil Corner / Re: How to create a line 1m down from crest of slope
« Last post by Lars on June 13, 2022, 02:12:57 PM »
Try this.


  • Move (or copy) your embankment edge (3D polyline down 1 m, using AutoCAD's move command. From(0,0,0) to (0,0,-1)). This edge will be used as a reference line
  • Use CadTools "Surface, Create Longitudinal Features"
  • Load your surface, set Foreslope to -50, set Distance to zero, set backslope to zero, set Ditch Width to zero. Since your reference line should be lower than the surface you don't need to change the Fill slope value.

You should disable "Tick Marks" (Slope direction markings)

This will make CadTools follow your 3D polyline and create a perpendicular line on the embankment surface. Like using a horisontal laser beam.
Beware of "Side of reference line" setting. The accuracy of the resulting line depends on the reference line and the intervall setting (And your surface)

Civil Corner / How to create a line 1m down from crest of slope
« Last post by Kimiko on June 13, 2022, 12:29:46 PM »
My project is on one side of a railway embankment, I have created a triangle surface using available data.
There is a line which marks the crest of slope.
I need to mark 1m vertically down from that line, but I'm not sure about the process to do so.

I have never draped a line before, but it sounds like the tool I need. However, the direction I want to drape is not on the Z plane.

Is this even possible?

I imagined a work flow would be...
Move crest line away in front of slope.
Lower crest line down Z axis by 1m
Drape (push) line back against slope to indicate a "contour" representing 1m vertical difference from crest.

Is this even possible?
Am I thinking of the correct process?

Any help would be appreciated.
Many thanks

Civil Corner / Re: Vehicle turning sim few questions

Hi,

A three wheel tractor doesn't use a Ackerman steering principle. However you can do the calculation with any type of truck since all calculations is based on a point placed in the middle of the two front wheels will follow the steering path. That point would be same if you use a three wheel tractor.

Copy a vehicle and save it as your tractor, set vehicle width and change wheel turning to 70 degrees. Be sure to use same units (Vehicle Path Units and Direction) as in your drawing when you edit the values.

Wheel size can't be changed by the user, it follows standard truck sizes and are for illustration only. However there are swept lines generated from the outer wheel shoulder, this is only relevant if the wheel width is wider than the body.
You can delete wheel by exploding the final block or change layer settings for Wheel outline and Tyre Tread and turn off that layer.
