ENVT1093 - Hasan Sahin - Group 3 - ArcGIS [11_1014] - 12.10.2017

GIS stands for Geographical Information System It is a system not a software. ArcGIS is the software. Opened ArcCatalog 10.5.1 Copied GIS_DemoPack ArcMap = 2D document ArcScene = 3D document Opened ArcScene file and orbit around. Opened ArcMap file and pan around. Opened attribute table (right click mastermap in layers panel - attribute table) Then followed a tutorial on how to use Digimap. This is available in the copied GIS_DemoPack as the .pdf named "GET DATA_2017_Fut Rep". And download of historic maps. Historic maps might have different scales of grid or measurement (imperial instead of metric) therefore it might be required the you "mozaic" (stitch) the historic maps to current grids. Gathering geological information from within the UK can be done using Digimap. Other regions outside the UK can be found by looking for DTM or other GIS information on Google for the specific region required or in ArcMap -> File ArcGIS Online. In...

ENVT1093 - Hasan Sahin - Group 3 - Rhino Session 2 [11_1014] - 05.10.2017

The second Rhinoceros 3D session was oriented towards a more advanced look into the software's surface editing capabilities, rendering with the V-ray renderer and parametric programming using the Grasshopper plug-in. We start by creating a simple profile of a train track that we extrude to 100m. Mirror the new rail to a set lenght. Underneath our new train tracks we create a simple extrusion to represent the supporting timber beams. We use the "Array Linear" tool to copy this extrusion 100m. Grouping this selection of beams and rails we make a mirror copy of it using the "Mirror" tool. This can be done by simply typing "Mirror" into the command log. We then proceed to create the train platform using a closed curve that represents the profile of the platform to be extruded. After having extruded the train platform we use the "Fillet" tool to join curves in rounded arcs and extrude the platform supporting V pillars. Similarly ...

ENVT1093 - Hasan Sahin - Group 3 - Rhino Session 1 [11_1014] - 28.09.2017

The first Rhinoceros 3D session of our group was split into 2 exercises meant to teach a basic understanding of the software interface and simple commands.  Exercise 1 : We began by having a look at the distribution of the interface and tools in Rhino. The first thing we observe is that the viewports are split between 4 quadrants of Plan, 2 Elevations and Perspective which makes manipulating your object easy as you can switch viewports by simply hovering your mouse over them.  Afterwards we had a look at the command panels and other function panels of the software a - File & Edit tabs b - Rhino command log c - Advanced commands toolbars and tabs d - Layers panel f - Properties panel g - Line snapping options h - Drafting Views i - Common commands toolbar Next we had a look at the polyline tool. This is the most common tool used in Rhino as the basis of any modelling in this software relies on crating surfaces from "curves" (a...
