Autocad Contour Lisp
Creating Contour Within Cad Hello everybody, Wecome to Video Tutorial on Creating Contour Map within your CAD Package. Contours can be generated either from point data available in Excel or CSV file or from the drawing file directly.

AutoLISP: External Contours of Objects Posted on March 29, 2012 by AutoCAD Tips This routine is helpful if you have overlapping objects that form a closed area and you would like to combine them into one overall closed object.
In this video you will learn how to generate the contour in CAD drawing file. In one of the next videos, it is explained how to generate contours with point data available in Excel or CSV. We will open the sample drawing file which has elevations and a boundary.
Before generating the contours we need to set contour generation preferences. This can be done by selecting “Contour Setting” option of Contour Sub Item in ESurvey CADD Menu. In “Contours settings” window we can specify parameters like contour interval, grid spacing, boundary generation factor. For this example – let us set 0.5 as contour interval, we will specify major lines for every 2 M, Select Smooth Contours from Contour Lines group. We will specify 5 M as grid interval and grid line spacing in Grid and Elevation lines group.
Since we will be selecting the boundary for contour generation, we will not make any changes to scanning radius in “Contour Calculation” group. We will select “Contour”, “Grid”, “Grid Elevations” in the output layer group. We will save these settings by Clicking on “Apply” button. In the next step we will select “Generate Contours” menu item. Now the software will ask for selecting elevation text. We will select all the levels in the drawing and then we will select the boundary when application prompts for the same. Poyasniteljnaya zapiska k balansu kazennogo uchrezhdeniya obrazec.
Now we can see that application has generated Contour, Contour annotations, Grid, Grid Elevation, Grid annotation all in a single command. Generating contours using ESurvey CADD is that simple [Here 2 Paragraph content – Take Content from Demo Video marked in Blue] It is good practice to define the boundary and select the same when creating the contours. In this sample we have a boundary along with elevations. Software c an automatically create the boundary in case boundary is not available. If you specify the approximate maximum distance between the points you have captured, which is termed as scanning radius in the software, the software will automatically create a boundary. After triangulating the data software will remove all the triangles having side lengths more than the specified values and create boundary by considering the remaining triangles.
Now in same sample, we will delete the boundary and generate contours without boundary. In this case software is creating imaginary boundary using data depending on Scanning radius specified in Settings. We can also generate contours with multiple boundaries, Islands, Break lines Etc. You can create a couple of boundaries in this sample data. When contour generation command asks for boundary, select all the boundaries you have created. The software will automatically leave out Islands and create the contours.
Note that Contour module can generate contours based on break lines, which is explained in one of the following videos. Thank you for watching this video. In the next video you will learn how to draw a profile on the contour surface using ESurvey CADD.
Contour Elevation Label Contour Elevation Label This command can be used to simultaneously create elevation labels on a group of contour polylines at elevation. Atlas pasportov stran mira vista. First the command starts with a dialog with the label options. Then to place the labels, pick two points crossing the contour polylines at the desired label location.
