Construction & Working Drawings - Discussion

I know how to cut in a real roof, I just feel it bit too much like work to have to individually push pull each rafter, and the sheathing.
It would seem there is a need for a "slice or cut tool" or ruby, i.e. "anything touching this plane is separated from it's geometry".....
how do you cut a hole in a wall as a simplified example... maybe I should try that...but sep. groups here...
thanks
like to see how your roof comes out, too.
aloha
redcouple of ways to get there:
if your rafters are all components - then simply drawing a construction line down from the face of the wall tracing it onto a rafter and clipping off the excess will alter all similar rafters. you'll need to go and adjust any thing that is 'unique'.
if they are all different (or not components) - copy the components you want to cut off to the side, leaving the originals in place. create a 'dummy' mass of the second floor - just a big block the same size. copy it over to the same location as the components above. open the various components that you need sliced. triple click once opened to select all geometry. right click. intersect with model. this will draw lines on your component(s) where they intersect that dummy block. delete what is unnecessary. again - any component that is identical will automatically alter... and you'll have to repeat for all components that are unique.
i'm a fan of building my model as i would with hammer and saw out in the field - so i'd go through the trouble of building my roof with repeatable rafter components to minimize work down the road, then cutting them to a ledger or ridge as needed to rest against the mass of the second floor. if you go through the trouble of modeling it correctly - you'll be able to use those details later on for construction documents.

Here's a use of LO& SU construction drawings that I hadn't expected.
I'm actually building the house (see above http://forums.sketchucation.com/posting.php?mode=reply&f=12&t=15911#pr234269) right now and during the foundation excavation I had some trouble explaining to the operator where he needed to dig and how deep. I didn't have any serious surveying equipment available so I couldn't do a typical transit layout, taking reference points and marking out angles etc. So I did some quick SU work to fit a set of triangles around the footing perimeters; anyone with a couple of tapes can lay out triangles.
My finished set didn't fit very precisely around the house but did always include every part. I drew up 6 triangles and then used LO to produce a sheet with 6 views, each one adding a new triangle to the one fixed line we had available.
It took a couple of hours working with the digger to convince him that by digging to my lines he would produce a useful hole in the ground but eventually it worked and the resulting hole will soon get its footings.

A new project... getting a bit faster. Still wishing for some more intuitive tools, and still wishing LayOut wasn't so damned slow...

bmike,
I am really liking these drawings. The 3D bolted connection details are great

Another example of this is Atelier Bow Wow.
hoooooly cinnamon buns!!!! this looks awesome, i'm already trying to forget about autocad and this is how i want my drawings to look like

Wow that's nice, I like that the bolts are textured and colored so the details are idiot proof. These days you need to make everything as clear as possible because assuming people know what they are doing can be a big and costly mistake. A person experienced in layout can really make a job go much more smoothly and save money too. Those drawings with the bolt details is a perfect example. Thanks for posting it.

Hello for all. I,m architect using SU 6 with LO. I'm using SU for the last 11 months, first to develop 3D model to customers. All CD was done in CAD. By now, after seeing LO gallery and earlier posts I decided to include LO to CD. I did prepare many scenes with floor plan, elevations and sections, but when I put scenes in the LO viewports the sections planes are still highlighted. Anyone could help how to fix it?
Thanks in advance.

Hello. After posting my question I returned to the SU and fix the problem. It is enough use "hide" in each section plane, save the file and update LO file. Very easy.
When my drawings are finished I will post here.

Hello to all in this thread
I have just uploaded to Google Warehouse my set of Electrical symbols and structural symbols including the Elusive DASHED LINE! To use the electrical symbols just open each component and hide the version you do not want. For the dashed line and arc just scale them to the drawing, edit component and get rid of the very stretched circle. For those who want to fine tune the process of creating dashed lines and get them to the right look for their projects here is the info: painful as it is, for a straight line you must draw a set of equal lines with equal spaces between (or any regular variation, I think mine were 1/4" each) and - here is the key - add a small circle to one end. Then make a component of it and it is scalable.
For the arc I just drew an arc, exploded it, made a component of it, and hid every other segment in edit mode. It too is scalable.After digesting every word in this forum topic it is time to give back to you all. At least I hope this is an original idea or I will feel real stupid

Hi Klog,
Thanks for those! I am not in this trade but I understand it will be extremely useful for some people!

I am very much impressed with the capabilities of SU... but I find CAD applications more easy and the results are more perfect the 3D view is also more accurate without containing any mistakes and it is trustworthy. I have been using CAD applications for about more than 2 years and I'm loving it
but there can be some more things that can be done by integrating both CAD applications and SU, like the use of DataCAD 12, import the SU features and then have DataCAD generate 2D elevation drawings. It can take a few minutes, but still quicker than recreating them from scratch, and cleaner than importing a dwg file from SU. So it can be more useful that just using a single software -

The simpliest and fastest way to do elevation (or any drawing) is SU+Layout.
So, in a way, you are right in saying not to use just a single soft. -

I don't agree with your assertion that SketchUp is inaccurate or creates mistakes. SketchUp is definitely capable of very high accuracy and precision. Mistakes or lack of accuracy are induced by the user.

agreed. sketchup is as accurate as the user makes it.

Hello,
I'm trying out the combination of SU and LO as an alternative to CAD. I added a picture from a test.
The picture at the top is a perspective view from SU, rendered in LO as vector. I added the dimensions in SU because there I'm sure which points I'm measuring. In LO the dimensions are sometimes off.
Question: can the leaders of the dimensions in SU somehow be hidden? I prefer just the slash.The second picture is a section cutface with the hatches from SU, rendered in LO as raster.
Question: Is there a way to improve the quality / crispness of the hatches? I use high res images as textures and my output quality is set to high.The third image is the section cutface without textures rendered in LO as vector.
The last image is a combination of all of the above in LO.
I'm not unhappy with the final image in LO but I would like to improve some elements. I hope someone has an answer to the questions.
Greetings,
Max

As far as I know the leaders for dimension lines cannot be altered - LO or SKUP. Second, I created some clear hatches from AutoCad by hatching a box in AC and making a jpg of it. Choose the lineweight in AC. Save the jpg where you would put .skm files, crop for tiling, and create a new material in SKUP using that jpg.
The "hatches" (read materials) in SKUP are subject to inherent styles apparently (someone correct me if wrong)and often include some screening effects.
I prefer the dimensioning to be done in SKUP for the same reasons you do. I will attempt to attach the concrete hatch made in this fashion.
Hope this helps some.

In LO they can be altered. Just double click on a dimension and you get some extra grips to alter the leaders.

It's a nice material you created but I think the base resolution of the texture in SU isn't the problem (I use 256x128 or 512x256 for a simple hatch like the attachment). I still would like to improve the sharpness in LO for those SU-hatches.
Greetings, Max

If you are using the stock hatches that come with Skup then you probably cannot change the sharpness. When you make your own you bypass that problem unless the style you are using for the scene incorporates some fade-out (fog). Thanks for the info on dimension leaders ...
