Imagine: you are rotaiting your model on your screen, and checking relationships between objects. when you are very close to front view, (you want to check some parallel lines) press ctrl and voila your eyecamera catch exact front view! Release ctrl, rotate more right, when you are close to right view (1-2°) use ctrl again to jump into exact right view. It is quick efficient way, which saves many widow switching and eye-searching. imho.

Latest revision as of 12:01, 18 July 2010

Here you can find a list of features we would like to see in Blender to improve Architectural workflow:

To do

Interactive rendering enhancements

OpenGl preview of materials and lighting in 3D view

  • non UV Texture display (the flat, cube, sphere, tube buttons in the "map" material panel)
  • procedural textures (for bricks in example)
  • bump, displacement
  • matte shadows
  • glossy
  • feel of GI/ambiant ligthing/occlusion
  • translucidity, transparency
  • mirror

All of that, tight close to Blender rendering settings. This means, non-coders users could use it easily. Material settings used for rendering are translated to draw the 3d viewport material so you don"t need to define material twice, one for rendering and another time for GL previewing.

Example in Truespace:

Dimensions

  • Proper units and measurement system, unlimited dimensions of the model.
    • A way to make things the right shape, size and location, rather than make something and then perform a series of commands to put it in the right place, then make it the right shape and size. (ie modelling in context)
    • Sufficient significant digits to convert between units with imperceptible error.
    • Input methods to handle various system conventions (Imperial feet and inches, Metric metres and millimetres, English decimal feet, light years, etc.)
    • Direct preference association with each model so that imports of various units are properly scaled.

Snap

  • More clever snapping : snap to midpoint, intersection, normal, extent.
  • selecting and moving of the 3dCursor
  • snapping to 3d cursor in the same way like snapping to vertex works.
  • snapping for loopCut, knife and slideVertices tool
  • create lines (edges) by numerical input (radius, angle, catesian co-ordinates) - this can be combined with face making and extrusion with numerical input to quickly make accurate shapes.

Tools

  • "measure" tool, or even "Dimensions" tool that can add dimensions in plan, elevations, etc.
  • a move tool that works relative to the Cartesian grid, rather than relative to the paper plane / camera orientation... ...so you can model in perspective, rather than a nineties four pane view
  • a rotate tool that works relative to the Cartesian grid, rather than relative to the paper plane
  • a scale tool that works relative to the Cartesian, rather than relative to the paper plan
  • a proper line tool that allows modelling in place (drawing the line where it is going to end up, rather than playing around plonking a random generic line object somewhere, then moving it where it should be
  • a tool to find the lost face of a degenerate solid (usually resulting from someone performing boolean operations on a complex series of shapes modelled without snapping) and stitch the 'lost' face back in.
  • a fenestration tool (doors, windows, etc...) for doing all the frames & such (cause it's SOOOOOO tedious to model and has to be right, as their design and construction is controlled by legal constraints in most developed countries)
  • a stair tool (cause it's SOOOOOO tedious to model and has to be right, as their design and construction is controlled by legal constraints in most developed countries and they are typically REALLY expensive to get wrong)
  • a terrain modelling tool suitable for production of a representation of a real world terrain that you might use to make decisions about how best to spend hundreds of millions of someone else's dollars, not an arbitrary approximation.

Parametrics

Some basic Parametric functions would be extremely useful. Some of these could be added as mesh modifiers. The basic premise is that one simple editable part defines a much more complex 3d model (non-visually editable).

  • Column defined by:
    • a single vertex (which provides the base point)
    • height
    • width
    • an x + y offset (so that the column can be either centred on a point, or have a corner on the point),
    • cross section type (square, round, other?)
    • (later) capitals and bases
    • (later) angle of axis
  • Beam defined by:
    • a single edge (which provide the base point, angle (on all planes) and length)
    • height
    • depth
    • a vertical and lateral offset (to define whether the beam is centred or offset)
    • Cross section type (square, round, I-beam, C-beam, Z-beam, etc.)
  • Slab defined by:
    • base plane(s) (preferably an Fgon or something), which provides the shape and size.
    • thickness (positive or negative)
    • thickness type (vertical, perpendicular, vertical to absolute value (flat base plane))

(slabs could also be used for rooves where the base plane(s) can be at an angle

  • Wall defined by:
    • an edge, or polyline (which provides the shape of the bottom of the wall)
    • height
    • thickness
    • lateral offset
    • height-type (relative height from base line, down to absolute value, up to absolute value)

(Down to absolute value is useful for walls topped by angled roofs, where the defining line is drawn at the height of the roof, angled, and the wall drops to the floor level)

  • It would greatly simplify a lot of applications if the above parametric objects could possess:
    • a composite surface type (i.e. multiple layers to the surface finish with configurable thicknesses)
    • profiles (i.e. a sculpted cross-section)
    • a distinct line weight when cut in a section to when seen from a distance
    • a vector 'fill' pattern inside the cut face, in section

Without them the parametric tools would be of little practical application in Architecture beyond initial conceptual work.

more complex, less important

  • hole (through walls, slabs, etc.
  • doors, with height, width, type, opening, reveal, etc
  • windows, similar
  • type modifications for walls, slabs, etc: brick walls, etc.

NURBS

Others

  • Possibility to set background image to anyhow angeled camera, not only for front, top, and right view..
  • "LayerManager" advanced layer managment. naming, grouping, and unlimited nuber of them (for import issue especially)
  • "LandscapeBuilder" a tool to build and plant real landscape based on contour lines.
  • Possibility to link to a database so to be possible to get "Bills of materials", to know "quantities" of a material is in the model (ie: to know how many cubic meters/feet of brick, concrete, marble,ceramic tiles, etc. or square meters/feet for paints, etc.) Maybe trying to link to OpenOffice database would be a possibility.
  • Better import/export of commonly used file formats like .DXF, .DWG, .3DS, etc.
  • A "PrintingEditor" that can work with the layouts and plot them "at scale". Printing capabilities for lines (continuous, dash, center line, etc. , thickness of a line, colors, etc. - all features that are needed to plot a complete set of construction drawings). If we could combine somehow Blender with a vector based tool - such as Inkscape, OpenOffice or similar - that might produce the result acceptable for "professional printing".
  • Easy use of Gameblender to visit our building like in a FPS game.
  • Texture baking for non UV textured objects
  • When you start rotate 3dview by MMB by accident of for checking puposes, so possibility to break this rotating (probably by RMB) and return view into angle should be very timesaving.
